Chapter one: Magic Duel Fail

Trixie blinked. Everything from the day before was a blur: She’d challenged Twilight to a magic duel to prove she was more powerful. She’d tried to perform an age spell. But after that she couldn’t remember a thing… what had happened? Did it go wrong somehow? She kicked about and felt something soft around her rump. What was it? She blinked, looking up to see a mobile over her head. There was something wrong, was that a mobile for foals? Why would she be sleeping under one?

Trixie slowly rose up and could see bars surrounding her. Was she in prison? No, the bars were made of wood and painted pink. She looked down to see a mattress and found that she held a plush teddy bear in her hooves. Then she looked around at the soft pink blankets, it was all coming together! She looked down to see a thick, white diaper around her rump, rising to her stubby little legs as she placed her hooves on her cheeks. Now she realized what had happened, her age spell had backfired on her!

The regressed magician groaned, rubbing her hoof down her face. "How couwd tis happen?! Did Twiwight do tis?!" Just then, something “poofed” into her crib.

Trixie turned to see that a small, grayish-purple coated little filly was there and she had a smug grin on her face as she replied. "Hewwo Twixie."

"Who awe ya?!" The blue coated filly cried out in surprise!

The grayish-purple coated filly placed a hoof on her chest as she introduced herself. "I Stawwight Gwimmew. Fiwst off, I gots to apologize, ‘cause I ta one who tuwned ya into a foaw."

"What?!" Trixie was beyond furious as she shouted. "Ya ta one who did tis ta me?!"

"Weww, I just wediewcted ya age spew. But yes, I did, “ Starlight explained. “I couwd've tuwned Twiwight into a foaw, but ten she wouwd just get back to nowmaw somehow. So I gots a better idea instead, I just needs to stay one step ahead of hew and hew fwiends. Fow tat to happen I need ya spy fow me on Twiwy and hew fwiends."

Trixie was starting to like this plan but she was still rather angry at Starlight and snapped. "Ya fowgetting tat ya tuwned Twixie into a foaw!"

Starlight held out her pudgy hooves and cried out. "Weww, if ya do tis and hewp me defeat tem, not onwy wiww I turn ya back to nowmaw but ya can join me in creating a utopia."

Trixie tapped a hoof to her chin. "Otay, but I a foaw. Is not wike Twixie is gonna give ya wetter of wha's going on."

Starlight waddled over and plopped next to her fellow filly as she continued. "I’ww come by a week watew." She then placed a plush bear into Trixie’s hooves and continued. "Whenever ya neaw Twiwy, and she tawking about someting important, ya press tis button and it’ww wecowd everything."

Trixie smirked and replied. "Ah, I see. So Twixie just gotta act cute and record Twiwy's secwets. Ten when you come back, I give it to ya."

"Exactwwy. Ya do tat and we gonna defeat them once ahd fow aww!" Starlight exclaimed, her cheeks flushing pink as she replied. "I wiww come back in one week...as an aduwt of course. Tis is onwy tempowawy.”

"Wight." Trixie snickered, wondering what this mare looked like as an adult and if maybe they could be friends later.

Starlight then waddled off as she waved a hoof and babbled. "Now, ya gots to pway nice and be a cute wittwe baby. Dun bwow ya covew."

The filly then suddenly disappeared, leaving Trixie with the spy teddy in her hooves. She held the plush bear close to her chest and nuzzled it. The regressed mare had to admit, the alicorn amulet was great but she had felt it taking over her mind, and who knows what would have happened if she let it continue.

Trixie laid back in her crib and pondered what would happen next. Then she turned to see Twilight getting up from her bed.

The filly was starting to wake up, stretching her hooves as Twilight looked over with a smile. "Hello, Trixie. I'm guessing you need a diaper change?"

"No I dun!" Trixie shouted but squeaked as the violet coated unicorn gently lifted her from the crib and gave her padded rump a few pats. Trixie was quite embarrassed to feel her padding squelch.

Twilight, however, wasn't phased at all as she yawned. "Sorry, I'm just way too used to this by now. Even your dirty diapers don’t phase me anymore." She lifted the little filly and placed her on a changing pad, going about cleaning her up.

Trixie whined and kicked the whole time, getting rather fussy. "Stop tat! I ta Gweat and Powewfuw Trixie! Ya can't tweat me wike tis!"

"Oh, stop! I can't leave you waddling around in a soggy diaper." Twilight snickered out loud as she continued the diaper change. All the while, the blue coated filly tried to fight back, kicking and bawling. But this Twilight clearly had enough experience with foals to keep Trixie from falling off the changing table. In a few minutes, she’d dressed her charge in new padding and a cute purple onesie with little stars printed all over. Twilight looked down at the blue coated little filly with a smile. "Rarity made that just for you."

"Next time, I'ww make her weaw a diapee!" Trixie snapped back as she was quite tired of this patronizing.

The violet coated unicorn just plopped the young filly on her back as Spike got up and looked over with a tired expression. "Guess Trixie decided to wake up early today?"

"She was out for most of the day yesterday, so I assumed she would wake up early. Besides, it's not the first time I've had to wake up early to care for foals." Twilight explained with a wink.

"Whatevew. So wha now, ya gonna feed me baby food?" Trixie grumbled in an irritated tone.

The violet coated unicorn mare couldn't help but snicker under her breath as she chirped. "Yep! Get used to it Trixie, foals like yourself can't digest real food," Twilight slowly took the little filly downstairs, placing her in a pink high chair and strapping her in. "This was Cadence's for a while, I had a feeling I would need it again."

"Gweat, ya just bwagging how smart ya awe." Trixie grumbled. Despite the fact that it actually wasn't Twilight's fault she was like this, it was still irritating to be around the mare.

Twilight shook her head. "Nope, I'm just being prepared. You know that both Ponyville and Canterlot had a lot of ponies turning into babies over the past few years, right? I don't get why you even came back, Trixie."

"Trixie towd ya yestewday! I wanted payback fow what ya did to me!" Trixie shouted at the top of her lungs!

The violet coated unicorn mare rolled her eyes. "Seriously? Payback for what? You did it all to yourself, and you even got yourself turned into a foal by using spells beyond your understanding."

Trixie grumbled under her breath, she wanted to say something back but knew that she needed to get on Twilight's good side. "Otay, fine, get it. I should stop twying to get my vengeance on ya."

The unicorn mare then beamed a smile at the little filly as she went to a cabinet and took out two jars of foal food. "Seems you learned your lesson. And for being such a good filly you get to choose breakfast: Mashed Bananas or Mashed Strawberries?"

The blue-coated filly cursed under her breath, but she had to admit she was hungry. Like Starlighthad said, she just had to deal with this patronizing for a week and then she could make Twilight suffer! She pointed at the jar of mashed bananas, and Twilight nodded.

The violet unicorn then tied a bib around Trixie’s neck, then began to feed her the food by spoon.

Trixie reluctantly chewed on the yellow mush. After a few scoops made it into her mouth. Trixie had to admit the food wasn't as bad as she thought it would be, it was actually rather sweet and tasty.

Spoon feeding was soon done as Twilight wiped Trixie’s mouth and chirped. "Alright, now for part two."

"No, not gonna have ya breastmilk!" Trixie shouted! She placed her chubby hooves over her mouth as Twilight gave a snicker. "Nope, just formula for you."

Twilight then plopped a bottle of formula into Trixie’s mouth. She watched Trixie suckle the formula with a motherly smile as the little unicorn filly glared at her, trying not to show that it was actually tasty.

But Trixie didn't even notice when she finished the bottle as she popped it out and Twilight chirped. "There we go, all fed."

"Twixie tinks tat breakfast was otay, but my mama's food was way bettew." Trixie grumbled as the violet unicorn then spotted the pudgy foal's tummy. She took a hoof and tickled the little foal's belly while making funny faces. "Oh come now, let's turn that frown upside down."

Trixie tried not to, but found she couldn’t resist as she started to kick her little legs while babbling and cooing happily.

The violet coated unicorn mare then picked Trixie up and nuzzled her. "Oh, you’re not so bad, cutie! Celestia and Luna were way fussier."

"Dun cawe, ta Gweat and Powewful Twixie is fussy!" Trixie cried out but then squeaked suddenly as she was placed over the violet unicorn mare's shoulder and given a few pats on her back, making her spit up.

After wiping Trixie's mouth, Twilight took her to the library where she sat down and placed the little foal in a playpen.

Trixie looked over and babbled, "I not gonna pway with baby toys."

"You don't have to, but I can't have you wandering off without adult supervision," Twilight responded. She then cleared her throat as she asked, "So, I think it's time I explain what's going on with you. But um, do you want the good news first or the bad news?"

Trixie eyed Twilight; she knew that Starlight Glimmer was why her age spell failed, but she still wanted to know if this Twilight would turn her back to normal. "Otay, good news first."

The violet unicorn mare nodded and continued. "Ok, the good news is I've actually researched the age spell you used yesterday. I assume it simply backfired and calculated how much power I need. So I should have you back to normal eventually."

"And ta bad news?" Trixie grumbled.

Twilight gave the little filly a suspicious look but continued. "The bad news is you used the alicorn amulet to use that spell, and Celestia and Luna have already forbidden me from using it because it’s too dangerous. So I'll be practicing age spell magic and trying to learn how to turn you back to normal within a month at the latest. Hopefully, we'll get there sooner rather than later. But until then I'll be your caretaker, seeing as I don’t know who your parents are or how to reach them."

Trixie pouted, it was obvious that it could take longer than a month. That age spell would be almost impossible for any unicorn to perform under ordinary circumstances. At least now she was a spy for Starlight, and had been promised to be an adult within a week. She would just have to spy on Twilight, give Starlight the spy teddy and make that pompous unicorn pay for what she did to her.

"Alright. I have a friendship lesson to write to Celestia, then we're off to Sugarcube Corner." Twilight proclaimed as she trotted over to her desk.

Trixie was a bit confused and asked. "Why we going to tis Sugawcube Cownew?"

"Oh, for your regression day party. It was Pinkie's idea, but I think since you'll be a foal for a while you might as well meet the other regressed foals in Ponyville." Twilight replied as she started her report.

Trixie pouted, plopping on her padded rump. The sooner Starlight could save her from this humiliation, the better!

Chapter Two: Trixie's Regression Party

After her breakfast Trixie was strapped up in a stroller, getting ready to be pushed out into Ponyville. The little filly sat there with a cute little pout as Twilight strapped a diaper bag around her chest, looking like her own mother. Trixie just turned her head and then saw Spike coming over, eyeing the little filly as he asked Twilight. “Do I have to come?”

“Of course not Spike, just make sure you have Trixie’s crib ready,” Twilight instructed. “Also, clean out the diaper pail an-”

“-Yeah, yeah. I did all that with Shining and Cadence.” Spike grumbled as he walked back upstairs to carry out his assigned tasks.

Twilight then got behind the stroller and chirped. “Alright Trixie, let’s get going!” She pushed her charge out the door and down the road as they headed to Sugarcube Corner.

But the light blue coated little filly cried out. “Wait, I not gonna have anyting to covew my diapee!”

“Oh, right! Sorry.” Twilight squeaked out as she turned to her charge and lit her horn, dressing her into a little purple onesie with little blue and yellow stars printed on it.

“Ugh, not tis again.” Trixie cried out, pouting. She then looked around to see ponies waving their hooves, snickering and dawwing at the little filly. She started to shout and snap at the passerbys but she only elicited more dawws and coos from the crowds of ponies. It was all rather embarrassing and rude to her.

But things got a lot worse as she wa brough to Sugarcube Corner where she saw what could only be described as a foalish birthday party had been all set up. The entire room was filled with streamers, balloons and a giant cake in the center of one long table in the middle of the room.

Pinkie Pie bounced over towards and exclaimed! “Happy regression day!”

Trixie squeaked, being rather surprised as she placed her hooves over her face! Once she lifted them she looked around and saw there were others: Rarity with her adopted sons Prince Blueblood and Hoity Toity (though both were in training pants) who running around playing tag, Fluttershy with Princess Midnight and Discord plopped into a playpen, Applejack with her adopted daughter Zecora (apparently bragging that she was fully potty trained to the colts as she chased them around the room).

Even the Cakes were there with the Cake Twins sitting in highchairs.

Trixie pouted. She didn’t want to have to endure more embarrassment but it was far too late by this point to escape that possibility.

“Alright let’s get everypony to the table and prepare for the cake!” Pinkie Pie exclaimed, then everypony struggled to gather their rambunctious foals and settle them down.

Trixie kicked and cried out, but Twilight strapped her down in a highchair along with the rest of the foals.

Pinkie Pie bounced in front of the foals and squealed in delight! “Alrighty! It’s time to introduce the newest regressed pony in Ponyville! Introducing: The Cute and Adorable Trixie!”

Everypony turned to the end of the table and clapped as Trixie squeaked, again trying to hide her face behind her hooves. She was too embarrassed to say anything at this point, but even this just drew dawws from ponies and giggles from the foals. She then slammed her hooves down the table and shouted! “Ya aww stop tis wight now! I stiww Ta Gweat and Powewfuw Twixie!” That of course only got more dawws from the audience..

Pinkie Pie then continued. “Well, she might only be a foal for a month or so, so let’s make sure we all make her time here special!”

Everypony clapped as Trixie just sat back, wanting to just leave.

Pinkie Pie then placed a giant cake decorated with blue frosting and pink and yellow icing in front of Trixie with just one candle placed on top. “Alright blow out the candle!

Everypony turned once more to look at Trixie. But she shook her head and snapped. “No, not gonna.”

Twilight snickered. “Oh, don’t be rude. Blow out your candle.”

“It not my biwthday!” Trixie snapped back.

Twilight gave the filly a glare. “It may not be your birthday, but Pinkie Pie and the Cakes worked really hard on this cake.”

Trixie slammed her hooves down again and shouted. “I dun cawe! I dun even know ta Cakes!”

“Oh, if the shy little filly doesn’t want to blow out her candle that’s fine.” Mrs. Cake cooed.

Trixie then pouted again, detesting that the plump baker had dared assume how she was feeling. “Not shy. Just dun wana blow on ta stupid candwe!”

Pinkie Pie bounced over and chirped. “Well, if the little itty bitty filly isn’t shy then she should blow her candle out.”

“Blow tan candwe! We want ta eat ta cake!” Blueblood shouted in impatience.

“Yea, blow ta candle out! Or ya gonna hear us shout!” Zecora chimed in, speaking in rhyme.

“Ugh fine!” Trixie shouted she looked down at the candle then blew it out and everyone cheered.

Pinkie then went and carved the cake and served it out to the other foals. As the ponies ate the cake and the adults talked to each other, Blueblood looked over and inquired of Trixie. “So, ya ta newest wegwessed foaw huh? How ya doin?”

“Pretty good I guess, onwy been a foaw fow wike a day.” Trixie responded as she munched on the cake.

Zecora turned towards the two with her face covered in cake and replied. “Weww, it’s nice to see anothew filly here, tough ya was pwetty mean fwom what I...uh...hear.”

“Nah uh, not mean! And ya dun have to whyme evewyting.” Trixie snapped back at the foals.

The little zebra cheeks flushed pink. “Otay, sowwie. I know tat can get annoying,” Zecora apologized and then continued, “Weww, doesn’t mattew, guess ya a new friend! And guess what? I potty trained and I can teach ya too.

“Tanks, but Trixie can go potty by hewsewf!” The little blue coated filly exclaimed.

Zecora poked at the little filly’s diaper. “Pwobabwy not, siwwy. Not when ya weawing tat.”

“Hey, dun poke tat!” Trixie whined. “I’ww prove it to ya, but not hewe!” She proceeded to finish her cake along with the rest.

Twilight then came by and popped a bottle of formula into Trixie’s mouth. “Let’s wash that cake down, huh?”

Trixie grumbled but reluctantly suckled down he rbottle. She smirked seeing other foals getting bottles or sippy cups as well. At least she wasn’t alone in that regard.

After the foals had all finished the cake, Blueblood and Hoity Toity continued their game of tag while Fluttershy was dealing with Midnight and Discord as they were fighting amongst each other. She scolded the two, placed them in a double seated stroller and then pushed them out the door.

The Cake Twins were taken aside for diaper changes as Trixie shook her head. Foals were disgusting, nasty and icky. And she’d somehow turned into one.

“Alright, cutie, how about you go play with your new friends?” Twilight cooed as she placed Trixie in a playpen with the Cake Twins. But Trixie just stuck her tongue out and then turned away.

Meanwhile, the little zebra skipped over and nuzzled Applejack. “Hey Mama, can I teach Twixie how to go potty?”

“Sure, that would be nice. But for now just go play with her, ok?” Applejack responded. She didn’t want a repeat of what had happened with Pinkie Pie when she’d tried to teach the Cake Twins (even if Applejack would personally supervise the teaching this time).

Zecora then tapped a hoof to her chin and then replied. “Mama, can ya put me in a diapee ten so I dun have to wowwy about making Twixie feew bad?”

“Ok kiddo, for little Trixie.” Applejack snickered as she taped Zecora back in a thick diaper and placed her in the playpen.

“Ya didn’t have ta do tat, Zecowa,” Trixie irritably grumbled. “I dun wike ponies doing stuff wike tat, cause ten I feew wike I have ta owe tem. Now I gonna have to wet ya teach me how to potty.”

“Nu-uh, ya seem ta need a fwiend and I taught it would be more comfowtabwe if ya tawked with me wike tis,” Zecora responded. “I tink tat we awso shouwd discuss on how ya can make fwiends with ta othew foaws.”

Trixie turned towards Zecora and reluctantly asked. “Otay, wha ya want me ta do?”

“How ‘bout ya put on a show?!” Zecora cried out.

Trixie tapped a hoof to her chin. “Actuawwy, tats not a bad idea...bu I need some stuff to hewp me pewfowm,” The little zebra then took Trixie by the hoof, showing her a top hat and some stuffed animals. “Weww...I can make do with some of tis stuff, but I need somethin’ to make cwouds of smoke.” Trixie insisted

“Oh, I gots ta perfect idea!” Zecora exclaimed as she scurried off to ask Applejack something. “Hey Mama, can ya give me some foaw powdew?”

“Oh no, you're not making another potion! Not here.” The farm mare protested.

“No, nothin wike tat! Just need it fow Twixie!” The little zebra immediately replied.

“Alright, well ya better not be doing anything crazy with it, ya here?” The farm mare warned as she reluctantly gave her little filly a bottle of foal powder.

Zecora scurried off to her friend and gave her fellow filly the bottle. The little blue coated filly eyed it and then took it up with a grumble. “Guess tis wiww do.”

“Alwight, we can do tis in fwont of evewypony!” Zecora cheered in delight!

“Oh, is Trixie going to put on a show?” Pinkie exclaimed as she bounced over. “Sorry, I couldn’t help but overhear your adorable little conversation. I’ll gather the foals up and then we can have the little show you’re planning, Trixie!”

She skipped off before Trixie could even protest and rubbed hooves down her face. “I guess is too wate now.”

“Yup! Now deaw with it!” The little zebra chirped as she gave Trixie a little foal blanket and tied it around her friend’s neck. “Thewe, now how about we go show how gweat ya stiww awe?!”

“Fine…”Trixie grumbled as she followed Zecora to the table and then stood on the table and proclaimed! “Awight, wisten up! I’m hewe to put on a show fow ya foaws!” She turned towards the foals and exclaimed. “Alwight, watch as I make tis pwush bunny disappear!”

The little filly took her blanket cape and threw it over the plush bunny then she slammed down onto her diaper, causing a cloud of foal powder to envelop her as she used her magic to make the plush teleport into a top hat.

Everypony gasped as the powder dissipated, revealing the bunny was gone! They all clapped and cheered at Trixie as she then waved a toy magic wand at the giant top hat, revealing it had nothing inside. Everypony gasped as Trixie gave a snicker. “Ah ha! Ya aww taught tat ta pwush bunny was gonna be in ta hat, but in actuality it was in Zecowa’s diapee!”

Zecora gasped, seeing the plush in her new pampers! She then used her hoof to dig it out and exclaimed! “Twixie wight! See? It wight hewe!”

The other foals all clapped their hooves and cheered as Trixie bowed. “Tank you! Tank you!” She was rather proud of herself as Twilight scooped her up. “Well, I think somepony had too much fun performing !”

Trixie wondered what Twilight was talking about before she looked down and squeaked! She’d peed her diaper and hadn’t even noticed.

“Alright, Little Miss Great and Powerful, let’s get you changed,” Twilight cooed as she took the little filly and placed her down for a diaper change. Fortunately, it was quick and painless. She then carried Trixie back to the stroller and strapped her in with the little bunny plush. “That was really adorable what you did back there. I hope you had fun!

Trixie didn’t say anything, not wanting to admit that she had actually enjoyed herself. She then turned to see Zecora toddle over as the zebra asked. “Ya will come pway at Sweet Apple Acwes sometime, rwght?”

“Um...whats tat? A fawm ow sometin?” Trixie scoffed back.

“Yeah, it’s our family’s farm, Trixie,” Applejack replied as she came over. “And if ya behave yourself, ya can come by any time.”

Twilight looked down at Trixie as they all waited for a response. The little filly grumbled, “Fine...but Zecora, ya gots to pwomice to teach me how ta use ta potty.”

“Otay, I wiww! Potty is wots of fun, you’ww see!” Zecora chirped as Twilight snickered and pushed Trixie down the road healing back to the Golden Oak Library.

Once returning to the library, Trixie was put down for a nap. She was dressed in a purple sleeper with a similar pattern to her onesie and then given another bottle of formula before Twilight placed her down in a crib. “Alright, you stay here and get some rest. I still have some stuff I need to do.”

“Ugh, how did ya get so good with foaw cawe?” Trixie grumbled.

“Trust me, It wasn’t something that I wanted either. But I had to care for my brother and his soon to be wife along with Celestia and Luna,” Twilight explained before blushing. “Plus, I was kind of a foal myself...though the circumstances around that were rather crazy,” She then tucked her charge under some foal blankets and kissed her on the forehead. “Now, do you want a pacifier?”

“Yeah, fine…” Trixie grumbled as a blue colored one similar to her coat was popped into her mouth. She gave it a few suckles. The little filly was rather tired and was starting to enjoy the soothing sensation from her pacifier. She had to admit that after miles of trekking trying to find jobs and working on a rock farm, this was actually rather relaxing. She eventually settled down as she closed her eyes and fell asleep.

Chapter three: Sweet Apple Playdate

The next morning, Trixie was being pushed down the street in a stroller and she couldn’t help but squeak and squirm with everypony watching her. It was so infuriating, she hated this town and almost everypony in it, especially when all they’d do is daww and coo at her.

But she endured it while hugging her spy teddy close to her, she was looking forward to using it. Twilight didn’t trust her and had been rather cautious around her. Trixie knew Applejack most likely will be the same, but Zecora was basically her daughter at this point. She could pretend to be her friend and then ask for some information.

But Trixie didn’t notice that Twilight looked down at her as she commented. “Well, you're looking rather smug this morning?”

Trixie grumbled before replying. “Oh just tinking tat I can’t wait to pway with Zecowa.” She hugged her teddy even more tightly as Twilight snickered. “Oh, you can’t be separated from your teddy. Did you give him a name yet?”

“Um, I dun know, guess Ursa is fine…” Trixie growled. She really hated the patronizing but she can’t blow her cover.

“Guess that’s a good name...I think I had a teddy named Ursa…” Twilight mumbled as she continued to push the stroller down the street, eventually reaching the farmhouse with the orchard surrounding it. And Trixie was soon placed down in a playpen alongside Zecora. The little toddler squealed, hugging the little blue foal and nuzzling her. “Oh I'm so glad you came! Come on, I wanna twy to bring you back to fame!”

“Put me down and stop with the rhyming!” Trixie shouted as she kicked about in annoyance.

“Eep, sorry!” Zecora apologized as she did as Trixie asked, placing the little foal down.

Twilight looked down with a smile. “Looks like they're getting along well.”

“I hope so, but just to be safe I’m gonna keep an eye on the two,” Applejack grumbled, still unsure of the situation. “After all that we’ve been through since this foal pandemic started, I ain’t takin’ chances.”

The two mares sat down on the couch and Zecora took her friend aside, seeing that there were a few interesting things from among the random objects in the playpen. Among them were a few pink balls as Zecora showed them and exclaimed! “These awe my smoke bombs! I made it with foaw powdew, but I wefined it to cweate mowe of a cloud. It shouwd help ya with youw iwwusions.”

“Oh weawwy?” The little blue coated filly whispered, rather amazed upon picking them up and seeing how soft they were. “So ya put wike a base awound it?”

“Yeah! It’s a pwastic but it’ww buwst on contact when thrown.” Zecora explained.

Trixie smirked thinking that it would be a good distraction for helping her find Twilight’s secrets. She then turned to see a little spray bottle and picked it up. She looked it over, wondering what it was. “Hey, what’s tis?”

“Oh tat is somethin’ speciaw. Watch!” Zecora replied as she picked up the spray bottle. She then sprayed Trixie’s diaper, making the little filly’s diaper appear to vanish.

“Hey! How did ya do tat?!” The little filly squeaked as she shoved her hooves over herself, suddenly afraid of being naked.

Zecora burst into a fit of giggles. “Hehe, see?! Wooks wike ya dun have a diapee now.”

Trixie scrunched her legs, hearing the crinkling from the padding as a smirk grew on her face. This would be even more useful than the smoke bombs! With this spray she could turn her teddy invisible and sneak it somewhere for hiding while Twilight isn’t noticing.
“Tis is gweat! How did ya make tis!” She asked Zecora.

Zecora got out a small notepad and flipped through the pages. “Hewe it is, a few mushwooms, sap from an owd oak tree in ta evewfwee fowest, and nectaw of the poison joke.”

“What poison joke?! It not gonna do anythin to me, wight?!” Trixie squeaked in fright.

The little zebra shook her head. “No, I distiwwed it. Ta magicaw pwopites have been weduced and it doesn’t wast wong either.”

Trixie looked down to see her diaper had reappeared and groaned. “Ya can make it wast wongew, wight?”

“Maybew. I gots to be cawefuw with poison joke, dun wana end up being a baby cow ow something wike tat.” Zecora explained with a blush.

Trixie just shook her head, hopeful of finding a way to make the spray last longer since it might come in handy. She then took one of the smoke balls and she tossed it up and down with a playful smile. She then tossed one of the smokeballs at Zecora, making a giant cloud of foal powder explode!

The little zebra coughed as she rolled out and shouted! “Oh yeah! Two can pway that game!”
She then tossed one of the smoke balls but Trixie dodged it as she rolled out of the way and soon the two were tossing smoke balls at each other until then the entire living room was covered in foal powder!

Twilight and Applejack wheezed as they got up, waving their hooves in their faces. The unicorn had to light up her horn to dispel the smoke around her.

The farm mare then turned her attention to the foals and snapped. “Zecora, stop doin’ that right now!”

Zecora’s cheeks flushed pink as she replied. “Sowie didn’t mean fow tat stuff to get evewywhewe.”

“Yeah, we just pwaying.” Trixie replied while shooting some cute puppy dog eyes.

Twilight was a bit curious as she picked one of the balls. “Huh? This is pretty intricate. Zecora, you refined the foal powder and put it under pressure using an aerosoul?”

“Yeah! It was hawd but Mama helped!” Zecora squealed, clapping her hooves in delight.

Applejack rolled her eyes and replied. “Trust me, you should be glad smoke is all that came out of that.”

The little zebra blushed and continued. “Yeah sowie about ta goo, and ta applesauce, ta foam….”

“Alright, we get it.” Applejack snickered as she picked up the little zebra and nuzzled her. She then placed Zecora down.

The zebra then waddled over and hugged her new friend, ruffling her mane. “Now I tink it’s time we twy showin’ ya how to use ta potty instead of ya diapees!”

“Yeah! Tat sounds wike a gweat idea!” Trixie agreed in excitement!

Applejack led the foals to the bathroom, pulling out a well worn plastic bowl. “Trixie, Zecora’s gonna let you borrow her trainin’ potty. Be careful with it, it’s an Apple family heirloom. It’s been in the family since Apple Bloom was a foal.”

“Bu wha about Zecowa?” Trixie asked as she saw the little zebra being stripped of her diaper.

Zecora grinned. “Mama’s got somethin’ speciaw fow me ‘cause I fuwwy potty twained now. If ya get good at using ta potty you might be abwe to do it too.”

Applejack just replied by groaning, moving a bit of a worn soft plastic seat over the rim of the toilet bowl and fixing it into place. “Zecora, I’m only doin’ this ‘cause Trixie doesn’t have her own potty and I ain’t got time now to go buy one,” She then bent down, helping the little zebra up. “I don’t quite think you’re ready to start usin’ the toilet yet, but for the sake of this demonstration it’ll have to do.”

Zecora just kept on grinning as she was delicately placed on the child seat on top of the normal toilet seat. “Wow, it so soft!” She exclaimed while looking down at Trixie! “Okay, you gotta take off ya diapee and sit on ta potty.”

“Otay, and then what?” Trixie asked, expecting some sort of magic trick that would speed up the clock. She was too impatient to consider the normal process.

Applejack only replied. “Then you just sit there until I say you can get up. If you do anythin’, I’ll wipe you up and then empty out the potty. If not, well you just try again the next time you think you have to go.”

Meanwhile, Zecora was happily declaring! “Wook, Mama, wook! I going potty in ta big potty!” And she could be heard audibly tinkling as the splashing echoed off the bowl.

Trixie, for her part, became jealous. She clumsily fiddled about with the tabs on her own diaper to try and undo it, and was quite humiliated when Applejack had to come over to help her do it. “I dun need hewp! I can do tis!” Trixie insisted and started trying to crawl toward the training potty. But she wasn’t prepared for the sudden temperature difference now that her bottom was bare.

Just before Trixie reached the potty, she felt a sudden warmth down her legs and the foal eeped as she saw a huge puddle forming underneath her! Frantically, she scrambled to the potty and sat down, hoping to get some of it into the potty. But only a few drops made it in.

The farm mare only sighed. “Don’t feel too bad, Trixie. Foals do that sometimes. Apple Bloom especially was really bad at this.” And she fought back a blush as she thought. “And it used to be worse when we didn’t have potties.”

As for Zecora, she wanted to hop down from her seat to console Trixie but didn’t dare due to how high up she seemed to be. Still, she tried to console her new friend from afar. “Is okay, ya twied.”

However, the little foal couldn’t help but feel jealousy anew wash over her. And it didn’t help that nothing else would come out of her.

After the little “accident” in the bathroom was taken care of and both foals were wiped clean (Zecora remained in diapers so as not to make Trixie feel bad), they were taken back downstairs with Applejack plopping the two troublemakers back in the kitchen. “Now you two just stay put. We can work on potty trainin’ some more later on if you both behave, okay?”

Both foals nodded as Applejack then got out a cut up peanut butter and apple jelly sandwich for Zecora, and fed applesauce to Trixie.

Once lunchtime was over, both foals were taken upstairs to Zecora’s bedroom. It was rather cute with stuffed animals everywhere, and there was a toy chest along with a table full of child-friendly flasks, test tubes and a small cauldron. Both were then placed in Zecora’s bed as Applejack then put up the rails. “Alright, you're gonna take a nap now: No ifs, ands or buts about it. And no makin’ any potions without supervision, Zecora.”

“Otay, Mama.” The little zebra grumbled but reluctantly nodded in confirmation.

The foals were then kissed on the foreheads and as Applejack left the room Trixie turned over and asked Zecora. “Hey um...gots a question, Zecowa...is there anythin’ happenin’ on ta farm?”

“Oh, nothing too cwazy. Some fwuit bats started coming over and sucking out juice but nothing ewse weawwy.” The little zebra replied.

Trixie smirked, that sounded like some useful information to give. “Weww, tat’s intwesting. Teww me mowe...”

“Weww, tey just coming by and sucking ta juice fwom ta abbwes,” Zecora went on explaining. “But it’s not that bad. Mama and hew famiwy keeps them fwom wuining the owchawd.”

“Yeah, but...oh nevewmind…” Trixie grumbled. She then took her teddy and laid back wondering if that was even useful. It’d been almost two days and she hadn’t gotten any useful information. But she was making friends, that might get them to lower their guard more. But she had to get something truly useful before Starlight came back or she was going to stay like this for a long time.

chapter four: Mama Twilight is back!

Later that afternoon, Twilight was outside of the Apples' home, staring at a young apple tree with a determined look on her face.

Applejack was standing next to her friend, somewhat confused, as she asked, "Ya thinkin' about practicin' your magic on one of our apple trees?"

"Yes, if that's ok…." Twilight answered. "I was studying age magic last night, and I don't feel ready with using this spell on Spike or anypony yet. I don't wanna risk making anything worse." She gave a deep breath while trying to concentrate.

Applejack was a bit unsure of one of her apple trees for Twilight's experiments, but she relented. "Alright, it's fine. But just this once, ok? I dun need ya turnin' all my apple trees into oranges or somethin'."

The violet unicorn gave a sheepish grin remembering how she turned a bird into an orange in an accident a few weeks ago, and replied. "Thank you, I won't." She centered herself and aimed her horn at the tree. It started to grow, but it suddenly began to shrink back to when it was a sapling! It ultimately turned into some seeds on the ground.

Twilight shook her head and looked somewhat defeated as she mumbled to herself, "That's all I can do? This is going to take a lot longer than I thought."

"Yeah, sure it looks like it, but let's hold off usin' your age spells on my apple orchard." Applejack grumbled to Twilight while looking somewhat disgruntled, glaring down at the apple seeds on the ground.

The unicorn cheeks flushed red as she scratched the back of her mane and apologized. "Yeah, sorry about that. I'll practice on other trees instead from now on." She then rose up and headed back to the house to check on the foals.

This recent experiment could take a lot longer; she couldn't risk harming Trixie or making her turn even younger. Then another realization came to Twilight as she walked inside the house. She was probably going to need more foal supplies...

Trixie woke up, and she realized she was now being pushed down the road, looking up to see Twilight was the one doing the pushing.

"Oh, sorry. You were still asleep when I picked you up." Twilight explained.

The blue-coated filly looked around and gasped, seeing they were in a familiar store! "Oh no, ya not doing a foal supply run!"

"Yes, of course. We have no idea how long you'll be like this; the spell you used was more complex than I realized," Twilight nonchalantly explained. She then went down the diaper aisle as she continued. "While you were napping, I took the opportunity to practice an age spell on an apple tree, but it backfired. Even if I can perform an age spell, I realized it could make things worse for you, regressing you to even younger than you are now. I...I don't wanna perform the spell until I'm sure that it will work."

Trixie looked upward. "Otay...but doesn't that mean I've been wike tis for wonger than a month, wite?"

"I'm not sure, but we should be prepared for a long haul... Twilight explained as she looked over the various diaper brands. She picked up some nighttime diapers with Luna's face on the packaging.

Trixie squeaked. "Oh, come on! Ya dun have to get me tose!"

"Hey, you soaked your diaper during that little nap. Plus, I heard about your potty accident. I would rather not be washing your sheets every day." Twilight jokingly replied.

Trixie grumbled as she laid back in the stroller, clutching her teddy. She and Twilight then continued through the aisles, soon heading to the plush aisle, and Trixie looked around at the long row of plush animals.

"I know you like that teddy, but I thought we should get some extra ones just in case you lose your other teddy." Twilight explained. She then started to pick out some plush bears, an Ursa minor plush, and even a cute, sparkling purple-colored teddy.

Trixie snuggled them all, loving the feeling of the plush bears as she hugged them close to her chest. Content, for the time being, she sat back in the stroller as she and Twilight continued down the aisle and headed to the cash register at the end of the store.

There, the cashier mare dawwed as she scanned the items. "Oh, is that the show mare that turned herself into a foal the other day?"

"Yeah…" Twilight rather sheepishly replied as she placed the plush bears on the conveyor belt.

Trixie pouted and snapped. "Fow ta wecowd, I didn't tuwn mysewf into a foaw my spew just backfired."

"Awww, what a cutie. And she even talks too!" The cashier commented.

Trixie was astonished. "Ya not surprised I can tawk?"

"You're kidding me, right? Do you have any idea how many talking foals I've met by now? At this point, I'd be more surprised if a foal doesn't talk at least a little." The mare laughed out loud as she punched the total amount of bits owed for the items on the cash register.

Twilight shook her head, hoping that more adults don't start regressing into foals anytime soon. "I really hope this age regression epidemic is over. Trixie's regression was just a small accident."

"Oh, they all say that. I'm already ordering a bunch of more diapers from Manehatten, just in case." The mare explained. She then hoofed a bag full of supplies as Twilight placed it under the stroller. Trixie placed her hooves over her eyes, feeling so embarrassed about the whole situation.

"Well, might as well be prepared," Twilight added as she hoofed a bag of bits for the supplies. She then pushed Trixie down the aisles and headed out towards the Golden Oak Library.

Trixie was placed back in her playpen after they got back. She did her best to distract herself by using her horn to lift blocks on top of each other. She turned to see Twilight studying relentlessly on books regarding age spells and writing down notes.

Trixie saw that Twilight was dedicating so much time and effort to turning her back to normal. But still...she wasn't entirely ready to forgive Twilight for more or less forcing her out of Ponyville.

But Trixie suddenly squeaked as she smelt something wafting from her, and her cheeks turned pink upon realizing she'd messed herself!

"Oh my, smells like somepony needs a change," Twilight yawned as she stretched her hooves and walked over, picking up the small little blue-coated filly and placing her down on a changing mat.

Trixie looked away as her diaper was changed, feeling her rump being wiped, then bombarded by foal powder, and finally the feeling of a fresh diaper as it was strapped around her rump.

Trixie kicked about in her diaper, feeling the padding as it conformed to her body. The new diaper felt rather snug around her rump, and she peered down at her tiny body, seeing that it was one of the new nighttime diapers that Twilight had bought for her. It was way thicker and poofier than the previous one she'd been wearing, as the padding had her legs spread out more.

Despite being a bit uncomfortable about the new diaper, Trixie found that it did feel somewhat comforting to have the extra protection.

"There, all finished!" Twilight chirped as she zapped the dirty diaper and incinerated it completely.

Trixie got up and plopped down on her rump. "Ugh, ya liking tis, huh? Humiliating ta Gweat and Powewfuw Twixie wike tis?!"

Twilight shook her head. "Of course not; I'm just a good foal sitter. Now, I think I've done enough studying so why don't you and I have some fun together? I was thinking of a small game of hiding and seek."

Trixie shrugged. "Otay, fine. But ya bettew not cheat! I Trixie was ta best at hiding and go seek as a foal!"

The older mare snickered. "Oh, sure you were. Well, too bad for you, I had a lot of experience with my foal sitter, Princess Cadance. I even read books on strategy at winning hide and seek."

"Ha! We shaww see!" Trixie giggled out loud. "How about we make a bet?!"

"A bet, huh?" Twilight asked out loud as she scratched her chin. "What are we betting?"

Trixie pondered for a moment on how this would work and what she wanted from Twilight. She looked down at her new poofy diaper and snickered, wishing to see Twilight be as humiliated as she had been. Trixie then pointed a hoof at the grandfather clock. "Otay, here's the deal. Ya have one hour to find me; if Trixie wins, Trixie wants you to...to wear a diapee!"

Twilight almost wanted to burst into laughter as unbeknownst to Trixie, Twilight had worn plenty of diapers for some time while she was trapped in the past.

The older mare, however, didn't know what she would want to have Trixie do if she lost...but the built up pressure from her nether regions made her realize her teats that had previously been used to feed foals like her brother Shining Armor and the other princesses were somewhat bloated. Twilight's cheeks flushed red; she now knew exactly what she wanted Trixie to do. "Ok then, and how about this? If I find you within an hour, I want you to do something for me."

Trixie paused, eyeing Twilight as she asked. "Otay, what's that?"

Twilight's whole face was now a beat red as she continued. "Um...well...I want you to drink one bottle filled with my milk."

Trixie pouted and grumbled. She'd wanted to see Twilight be humiliated like how she had been for the past few days. But if Twilight won, Trixie would have to suckle the milk of her rival?!

Well, Trixie felt assured of her victory. So she smirked and declared, "Alwight, fine ten. I accept ya terms." And before Twilight could even start the countdown, the little foal toddled off giggling and laughing to herself. She climbed the stairs as Twilight shook her head and placed her hooves over her eyes, and counted down from ten.

Trixie found a place in Twilight's closet and found a stash of diapers. Trixie had a smirk on her face, figuring this would be the last place Twilight would think to look! She dug under the mountain of packages of pampers, snickering to herself and feeling rather excited.

Trixie then peeked out, wondering how long it would take for Twilight to find her, only to squeak upon seeing Spike standing over her. "What are you doing hiding in here?"

Before he could say anything, Trixie took Spike's right claw. She threw him into the packages making him burp out some fire and causing some of the packages to catch on fire and explode, burying the two in a mountain of neatly folded diapers.

Spike wanted to shout, but Trixie placed a hoof over his mouth and whispered. "Twilight and Twixie awe playing hide and seek, alwight? So stay quiet."

Trixie removed her hoof, and Spike snapped. "Ok then, but I'm not going to be caught in a bunch of diapers! I'm getting out of here!"

"Stop ya talking and squirming! If Twilight doesn't find us, she won't see you wike tis." Trixie snapped back.

They both squealed, hearing hoofsteps coming up the stairs and Twilight asking out loud. "Spike, have you seen Trixie? Spike?! Trixie?!"

Twilight started looking around her bedroom. Both Spike and Trixie were now being as silent as possible, both having their own reasons for not wanting to be caught. Then they heard Twilight getting closer to the pile of diapers. The violet-coated unicorn couldn't help but chuckle as both Trixie and Spike heard her ask out loud. "Hmm, I wonder who could be under all of these diapers?"

Spike gasped, and Trixie squeaked; it was evident that they were about to be caught! Trixie took action as she lit her horn, planning to push Spike out in the open. The young drake turned and glared at her. "Don't you da-"

But Trixie shoved Spike out of the pile of padding with him falling on the floor next to Twilight (who looked down with a surprised expression on her face).

Trixie took advantage of Twilight being fixated on Spike as she ran downstairs, giggling to herself. With Twilight distracted, she had the opportunity to find a better hiding spot than before!

Spike was frozen in place, looking upward at Twilight, who had a smirk on her face as she cooed, "Spike, would you like to explain why you're in the foal supply closet and covered in diapers?"

The dragon stood up with steam coming out of his ears and shouted, "Trixie did this! I found her hiding in the closet, and then she shoved inside. I accidentally burned some, causing the packaging to burn off, and we got covered in diapers."

Twilight eyed her assistant. He had lied to her before, but it seemed likely to be the truth from the sounds of things. "Ok, did you see her run off?"

"No! But she obviously isn't here anymore!" Spike roared, throwing the random diapers back in the closet.

Twilight threw her hooves in the air and asked nonchalantly. "Hey, if you want to wear one...."

"Buck, no! Like I said, Trixie made this mess, and I just got caught in it!" Spike snapped as he stamped downstairs. "I don't need those stupid things anymore; I haven't worn them since you potty trained me all those years ago."

The violet-coated unicorn simply burst into laughter as she followed her assistant. They promptly looked all around the library, the kitchen, and the bathroom as they checked every nook and cranny. But there was no trace of the foal. Twilight grumbled as she looked at a grandfather clock nearby. "Ugh, I only have ten minutes left! If I don't find her, I'm wearing a diaper again!"

Spike was also helping Twilight, currently looking through the kitchen cabinets. "Ugh, where did she go?! Did you check upstairs?!"

"Yes, I've checked everywhere. She could've gone outside, but that would be cheating." Twilight replied. Then she tapped a hoof to her chin; Trixie had to be in Golden Oaks Library somewhere. She was clearly much cleverer than Twilight had given her credit for.

Twilight then turned to the playpen. At first, she hadn't taken notice, but there was a pyramid of blocks. She didn't even realize how obvious it was. Twilight slowly walked over, levitated them, and revealed the blue-coated little filly underneath who whined. "How did you find Trixie?!"

"Oh, come on, I should've realized it much sooner that you made this pyramid by yourself," Twilight replied as she scooped the foal up and nuzzled her. "In fact, you're a really smart foal." She placed Trixie on her back as the little filly groaned, knowing what was going to happen next...she was going to be breastfed!

Trixie was now in a highchair with a big foal bottle full of creamy milk. And Twilight was smiling down at the filly. "Oh, come on, it's not that bad."

"Yeah, come on and drink up." Spike jeered, still angry at Trixie.

"I going to," Trixie grumbled under her breath, was hesitant to drink the milk of her rival. But it did smell rather sweet with a hint of apple. Trixie could feel drool coming down the side of her chin as she took the bottle, placed it to her lips, and began to suckle down the breastmilk. She was shocked as the creamy milk went down her throat. It was delicious!

Trixie closed her eyes as she suckled down the bottle taking her time to drink it up. After she was finished and was suckling air, Trixie gave a loud belch and spat some of it up. But Twilight already had a small spit-up rag and cleaned Trixie's mouth.

Twilight gave Trixie a smile and nuzzled her. "Did you like my milk?"

Trixie whimpered, not wanting to say it out loud, but it had been rather delicious. And on top of that, she was feeling rather tired all of a sudden.

"Come on, let's get you to bed," Twilight whispered into Trixie's ear as Trixie was then gently carried upstairs and placed down in her crib.

Trixie felt the covers go over her body and be tucked underneath rather snugly, then she felt a pacifier plopped into her mouth. Trixie felt the rubbery bulb bobbing up and down, then felt her plush teddy being placed in her hooves. The foal felt so safe and secure, and deep down, she had to give Twilight credit; she was actually pretty good with foals.

Chapter Six: Trixie's Many Firsts

Trixie had an adorable pout on her face, looking rather annoyed as she was being pushed down the street by Twilight, who was simply humming a tune to herself. The little blue filly was pouty due to the fact she had just endured a few hours of having to do an embarrassing magic show routine and was just glad that it was over.

Trixie now looked around with an embarrassed expression on her face, seeing that she was wearing nothing but a diaper around her rump. At least, it was a simple white (and rather poofy) diaper. Still, Trixie couldn’t help but throw her hooves over her exposed padding and was trying her best to cover it up. The filly was starting to feel self-conscious from ponies continuing to stop by, waving their hooves at her, or commenting at how cute she looked.

Twilight took notice as she looked down at the foal with a reassuring smile and cooed. “Don’t be so shy all the time; who knows how long you’ll be like this? You might as well enjoy it.”

“Tats easy for ya to say!” Trixie snapped back at Twilight as she plopped her charge down into the stroller with a pout on her face. “Why we goin’ to Abbwejack’s anyway?”

The violet unicorn lifted her head up and continued. “Well, I can’t say for sure. But I figured you can play with Zecora while Applejack and I do some big pony things that we need to take care of.”

“Weawwy?” Trixie asked. “You so secwetive.”

“You have no idea.” Twilight snickered as she continued to push Trixie along without making a fuss.

The little filly then just settled back into the stroller and cuddled her spy teddy close to her. Despite having just come from a rather embarrassing morning with Twilight having Trixie couldn’t help but ponder about how relaxing it was being a foal: Being able to sleep in and just being fed bottles and some rather tasty oatmeal. She had to admit being a foal had its perks, minus the diapers and constant coddling, of course.

Trixie was lost in thought when she looked up rather suddenly and happened to notice that she was at the Apples’ house and there was Applejack opening the farmhouse door. “Hey, Twilight, glad to see you came!”

“Yes, it is; oh you should’ve seen how adorable Trixie was practicing all day for her show tomorrow. She’s definitely going to be the talk of the town.” Twilight chirped with a smile as she then walked inside and placed her little filly down into the playpen already setup.

Trixie’s cheeks flushed red at the compliment, knowing that her show would be both fun and rather embarrassing. As the little filly was plopped inside the playpen she took a moment to look around, seeing the toys were relatively simple: Some wooden blocks and a few plush animals all looking homemade. The little filly trotted over to the blocks as she decided just to try practicing using her magic while the adult mares continued their conversation.

“Oh, that does sound rather cute. Zecora’s mostly been just playin’ with her potions all mornin’. She’s trying to make smoke grenades for Trixie’s show tomorrow.” Applejack replied. Soon the mares were deep in a conversation about their charges, almost like they were actual moms.

The filly tried to pay attention, but she mostly concentrated her magic to lift blocks. “Come on; I can do it,” Trixie mumbled under her breath, taking all her strength to levitate the blocks and stacking them neatly on top of each other. The filly showed off a proud smile upon noticing that she was improving.

Just then, Big Mac trotted over with little Zecora on his back, and she waved a hoof upon seeing Trixie. “Hey, Twixie! Glad ta see ya came by!”

The little blue filly flashed a smile back, then waved a hoof at her friend and greeted her back. “Yeah...nice to see ya too! Wook! I can use my horn!”

“Oh, wow! You gettin’ better at tat!” Zecora commented with an astonished expression on her face.

As the big red stallion placed Zecora down in the playpen a moment later, Applejack turned to face her brother with a stern look and ordered, “hey Big Mac, you're gonna have to be watchin’ the foals while Twilight and I are gone. You keep an eye on them; I don’t want any funny business while we’re out.”

Big Mac gave a slight nod and a nervous sounding. “Ey’yup!”

The farm mare looked down at Zecora with a glare. “That means no makin’ potions and no potty trainin’ with Trixie while we’re gone, ya hear?!”

“Yes, Mama.” The zebra squeaked as she hid her face behind her hooves.

Applejack continued trotting over to Twilight and asked, “Now why don’t we do some pracitin’?”

“Right, we’d better get going,” The unicorn responded as she got up and trotted over to Applejack’s side. She then eyed Trixie as she said, “You better be on your best behavior as well.”

“Trixie will!” The filly snapped back as she used all of her energy and squinted, using her horn to place another wooden block on top of the others slowly. She gasped upon seeing that she’d done it without having a magic burst and clapped her hooves together. “Wook, Twiwy, I did it again! Ya, see?!”

Trixie’s adorable outbursts were greeted with a loud “Awwww!” by everypony around her.

The violet unicorn placed a hoof to her chest with tears in her eyes. “Oh, you're growing up so fast.”

Trixie gulped and lowered her gaze as she was now feeling somewhat embarrassed. It was so awkward getting praised for basically doing nothing, but it also felt really good for some reason.

Twilight slowly came over and nuzzled Trixie. “Oh, stop being so embarrassed. Your magic is progressing pretty well for a foal your age. Now just have fun and relax.”

Trixie eyed the two mares with a ton of questions going through her mind and asked. “Wha awe ya two even doing?”

Twilight booped Trixie’s nose then cooed. “Sorry, that’s a secret.” She then trotted off with Trixie watching Twilight with a glare, wondering what exactly was her rival up to?

“Hey, can I hewp ya build a tower?” Zecora asked with that lovely little smile of hers, interrupting Trixie’s thoughts.

The little blue filly gave a slight nod. “Yeah, tat’s fine.” Trixie was preoccupied with her own thoughts as she wondered about what she’d do next and what Twilight was doing with Applejack.

While Applejack and Twilight walked off, Trixie busied herself playing with plushies. The little filly thought and reflected on her predicament. She had more or less a guarantee of turning back to normal with the information she had on Twilight (who obviously had something that could derail Starlight’s plans). But if Twilight did have a way to change Trixie back to normal? Would it be better just to let Twilight cure her? Or what if it was the worst-case scenario: Twilight’s secret didn’t work, and then Starlight betrayed Trixie!? Would that mean she was stuck in diapers forever!”

Zecora, unaware of what was going on in Trixie’s mind, trotted over and asked. “Um...Twixie, awe ya doing otay?”

The little filly looked over at the zebra as an idea crossed her mind. She needed to figure out at least what Applejack and Twilight were doing in the apple orchard, and she also wanted to get out of these embarrassing diapers. So she replied. “Yeah, I fine...um Twixie gots a question?” And then she asked. “Can ya help me with potty training again? Twixie wants to twy it again.”

Zecora nodded, but she started to twiddle her hooves as she stammered. “Yeah, of course...but Mommy said we can’t do tat wight now.”

Trixie trotted over and gave Zecora the most adorable puppy dog eyes look. “Oh, come on! She outside doin’ somethin’! It’ww be quick, she’ll neva know.”

“I seriously want to, but…” Zecora pointed a hoof at Big Mac, who was sitting on a nearby couch, reading a book.

Trixie nodded, knowing they would have to ditch the big stallion to sneak to the potty. She started suckling on her hoof, thinking of a plan, “Hmmm. Mama said ya made some smoke bombs?”

“Yeah! I wanted to give them to ya for ta show!” Zecora squealed as she showed off some pink-colored plastic balls.

Trixie squealed as she took them into her hooves. “Wow! Tese wook amazing!”

The little zebra’s cheeks flushed pink as she admitted. “I haven’t tested tem yet, though.”

Trixie took one of the smoke bombs and brought a hoof to her mouth as she snickered. “Weww, why dun we test tem on ya uncwe?”

The little zebra started to get rather excited as she whispered. “Otay, sounds wike a plan...but we gotta make it wook wike an accident, so I dun get in twoubwe.”

Trixie then took one of the smoke bombs and snickered. “I have an idea! Just follow my wead!”

Without warning, the two foals began to throw stuff at each other, having a fun little game of using other plush toys as projectiles! Trixie then took the opportunity of picking up one of the smoke bombs and tossed it at Zecora: She ducked as the smoke bomb hit Big Mac, and the room was covered in a thick, white fog of smoke!

The zebra then took her friend by the hoof, and they ran off down the hall, giggling as they headed towards the bathroom together. They then went inside the bathroom as Zecora showed her friend a plastic pink training potty, and Trixie had a shy smile. “Ugh, do I have to?”

“Memba wast time? Ya barely even made it to ta twaining potty,” Zecora replied with a nod. She then pointed her hoof at the diaper and asked. “Now, do ya need help?”

“Yeah,” Trixie grumbled, standing on her back legs to let Zecora untape her diaper. When it came off. Trixie trotted about it feeling proud that the embarrassing diaper was finally gone! But she did sort of miss the warm, comfy padding around her rump.

“Come on! Get on the potty, quick!” Zecora exclaimed as she hastily placed Trixie down on the training potty.

There, the little blue filly’s cheeks flushed red as she asked. “Y...ya gonna watch me?!”

“Why not?” The zebra innocently asked.

Trixie was starting to feel even more embarrassed than being in diapers as she shouted! “ Just look away, pwease?!”

Zecora’s cheeks flushed pink again as she nevertheless looked away, soon hearing Trixie tinkle in the training potty. Trixie closed her eyes, being super embarrassed. But that feeling slowly melted away as she finished. Afterward, Trixie felt somewhat relieved and excited that she’d just gone potty as she squealed! “See, Zecowa?! I went potty all by myself! Did ya see tat?!”

“Yeah, I did! I told ya can do it!” Zecora squealed as the two little fillies hugged each other. The zebra then helped Trixie wipe, and with a great deal of effort, dumped the contents into the toilet.

As the little zebra flushed it all away, they could hear Big Mac shouting down the hall. “Hey, where did you foals run off to?!”

Trixie gnashed her teeth and cursed. She’d been hoping for more time since going potty wasn’t the only thing she was after. “Hey, Zecowa! Wanna see another twick?!” She called, straining herself to use her magic to push the little zebra into the toilet!

“Wha ya doin’?!” Zecora asked before she heard the sound of the toilet handle was pressed down with Trixie’s magic, and she screamed and spun helplessly around in the bowl as a result!

The little blue-coated filly ran off down the house as Zecora shouted! “Hey, whewe ya goin’?! Dun weave me!”

The blue-coated filly couldn’t respond as she continued running down the house; she needed to see what secret Twilight was hiding from her and figured this would probably be her only chance!

Trixie ran out the back door of the farmhouse, still bare-bottomed. With any luck, Big Mac would be distracted rescuing Zecora and wouldn’t be looking for her for a long time. She then slowly trotted over as she headed towards the orchard. When she saw Applejack with Twilight, she hid behind one of the apple trees keeping an eye on the two with a devilish smirk on her face. Trixie now had a devilish smirk on her face as she thought to herself that she’d done it! She was about to see what Twilight had been hiding from her!

With her spy teddy handy, Trixie turned it on and waited paitently.

“Alright, are you ready?” Twilight said to Applejack.

“Yeah, yeah. I'll only be a foal for a few seconds, right?” Applejack nervously asked.

“Yes...now please, just try to relax.” The unicorn whispered as she lit her horn and concentrated.

Trixie noticed the amulet around Twilight’s neck: It looked similar to the alicorn amulet, but this one had small horns, had a chubby face and stubby horn on its center, and it was bright pink. The amulet glowed as Applejack was slowly regressed in age.

When the magic tendrils dissipated, it revealed the farm mare with her hat now covering half her body. “What the hay di ya do to me,Twily?!” Applejack cried out as she threw the hat off, revealing that she was now a young filly, pudgy with thick little hooves and a stubby mane and tail.

Trixie had to stifle her laughs behind her hoof, seeing that the farm mare was now no older than maybe three.

Twilight clapped her hooves and squealed in delight. “Oh my Celestia! You look so adorable, Applejack!”

Applejack whined as she started doing a funny little dance. “Otay, now will ya turn me back to normal?!”

“Aww, does somepony needs to go potty? Or maybe you’d prefer a diaper?” The unicorn teased her regressed friend, knowing by now what that little dance usually meant.

The regressed farm mare started to throw a fit as she whined. “Just turn me back to normal, quickly!”

Twilight snickered, seeming to be rather enjoying seeing her friend in such an adorable state. But eventually she did as Applejack requested as she lit her horn. The little filly was turned back into an adult almost seamlessly.

“There, it worked! It can track the age a user is supposed to be at and even regresses on command to the year the user wants.” Twilight explained in a rather excited tone of voice.

Applejack was stunned, looking over her body while making sure everything was normal before she whispered. “Yeah...that was surreal…”

“Well, now if anypony gets regressed against their will, we can turn them back immediately, hopefully,” Twilight sighed, looking somewhat relieved at that prospect before she then continued. “But...I’ll need to test the amulet out a few more times to be sure. I’ll need to try it probably on pegasi and unicorns as well, but I should be able to turn Trixie back to normal.”

Applejack turned to face her friend and then asked. “Yeah, but what about her magic show? A lot of foals are actually looking forward to that, aren’t they?”

Trixie held close to the tree and even stopped breathing for a second. Would she be saved from being humiliated tomorrow?

Twilight shrugged as she stowed the amulet away in her diaper bag and declared. “I’ll let her decide if she wants to do it. Luna made her such adorable diapers, though.”

Trixie stepped back as she shut her teddy bear off. She had enough; now she knew the secret Twilight was keeping from her: An amulet that helps with age spells. That definitely would be a hindrance to Starlight’s plans. She had to steal that amulet! But...Twilight was supposedly able to turn her back to normal now; could it be done today? But if so, what then?

Trixie thought hard. She hadn’t forgotten how Twilight had humiliated her a year ago and how Twilight had been treating her like a helpless foal! And not only that, she’d been making Trixie wear humiliating diapers and clothes! “No,” She thought to herself. “I don’t just want to turn back to normal anymore! I want to see Starlight’s plan come to fruition!” So, for now, she’d stay a foal and just steal the amulet instead!

“Hey, there ya are!” Big Mac exclaimed as he trotted over towards the filly looking somewhat relieved as he picked Trixie up and asked. “What were ya doing out here all alone?”

“Um...I...um… wanna see apple twees? Can you buck some abbwes, pwease?” Trixie stammered as she flashed her puppy dog eyes.

Big Mac gave a small daww now being completely hypnotized by Trixie’s adorableness as he then nuzzled her. “Alright. You shouldn’t be runnin’ off by yourself, but I can show ya how to buck apples for a bit if ya want.”

“Yeah! Tat sounds like fun!” Zecora exclaimed, looking only slightly worse for wear after what Trixie had done to her.

“But somepony needs a diaper first, even if Zecora says you went potty.” Big Mac chuckled as he laid the little filly down on a changing pad he’d brought with him and started to tape her up in a fresh diaper.

Trixie grumbled under her breath but allowed the strong stallion to tape her up in a fresh diaper. It was a small price to pay for the sweet victory of not only knowing Twilight’s secret but also progress on using her magic and using the potty! After Trixie was padded up in a fresh diaper, she trotted over, feeling rather comfortable with the padding around her rump.

Zecora turned and waved a hoof at her. “Hey, gwad to see ya otay! I was worry when ya just wan off wike tat. Ya gotta warn me ta next time ya gonna do tat, ya almost made be wike Hoity Toity and Bwuebwood who went down the howe! My diapee saved me!”

“I knew ya’d be otay; I needed to make a distraction,” The filly apologized. “I just weally wanted to see aww tese abbwe tees!” She exclaimed with a cute grin.

“Oh yeah, tey awe pretty coow. I love watchin’ Applejack and Big Mac buck the tees all ta time!” The little zebra commented back.

Trixie trotted over and plopped down next to Zecora. “Otay ten, wets watch together!”

Big Mac scooted the foals back a bit. “Ok, just y’all stay back here, alright?”

The two foals nodded and watched in anticipation to see Big Mac’s thick hooves smack into the apple tree that was in front of them. The tree shook as apples plopped down in the baskets below, making the foals coo in delight. Big Mac continued to smack the trees repeatedly as he continued to make apples rain down into the baskets below.

Trixie and Zecora clapped their hooves, both being rather impressed by the earth pony’s strength.

Trixie then trotted over and tapped at Big Mac’s leg. “Uh...Big Mac ca...can I twy?”

“Sure, go ahead. But be careful.” Big Mac cooed. He gently let the filly face her padded rump at the tree, watching as she started to smack the base of the tree with her tiny back hooves.

Zecora stood up, cheering her friend on. “Come on, Twixie! Ya can do it!”

Trixie kept on smacking her hooves into the tree until a single apple fell from the tree and plopped into the basket below. The little filly stood there, heaving with sweat all over but with a proud smile on her face.

“You did such a great job!” Trixie heard Twilight cheer as the unicorn trotted over, picked the filly up in her magic, and nuzzled her.

The little filly couldn’t help but flash Twilight a smile. So many firsts today: Her first time really using magic, going potty, finding out secrets, and even bucking apples! It was a great little day full of small little victories.

Twilight promptly placed her charge down into a stroller, strapping her in. “Alright, we’d better get going. I have to tell Celestia what we learned, plus get Trixie to take her nap.”

“I not tired!” The filly whined but then gave out a rather cute yawn making everypony dawww.

Applejack scratched her head, eyeing the little filly as she asked out loud. “Say, what was Trixie doin’ out here in the first place?”

“Oh...um…” Big Mac stammered.

Trixie knew she had to say something to remove any suspicion. So she looked over at Applejack and soon said. “Is just tat I wanted to see Big Mac buck abbwes and wan outside to have him chase me!”

Zecora bounced up and down. “Yeah, and guess what?! Twixie alwo went potty with a wittwe hewp fwom me!”

Trixie let out a groan as both Twilight and Applejack glared at Big Mac, who stepped back. “They threw a smoke bomb at me!” He nervously insisted.

Applejack then turned her anger at Zecora. “Is that true?”

The zebra’s cheeks turned a hot red as she whimpered. “Yeah, a wittwe…”

“Well, Twixie thwew ta smoke bomb! And Twixie awso wanted to go potty so dun bwame Zecowa, blame me!” Trixie exclaimed! Despite her hating being a foal, Zecora had been her one true friend throughout this ordeal, and she didn’t want her to get into trouble for her actions.

Twilight trotted over and ruffled Trixie’s mane. “Ok...well...did you use the training potty and not the big one?”

“Yeah...and Zecowa was ta one who flushed ta contents down the big potty,” Trixie replied, trying to be as blunt as possible and not wanting to go into details.

Twilight gave a nod as she replied, “Well, that clears things up. It seems nopony was hurt, and the foals seem rather happy, but I would advise we confiscate the smoke bombs.”

“Yeah, should’ve known they would only cause trouble.” Applejack growled and eyed her charge.

“Weww, wike Twilight said nothin’ happened,” Trixie quickly replied. “So why dun we get somethin’ to eat and then I’ve take a nap?”

“Sounds good to me!” Zecora squealed as she bounced up and down on the farm mare’s back as she, Applejack, and Big Mac headed back to the house.

Twilight then strapped Trixie into her stroller and gave her a playful nuzzle. “Alright, cutie, why don’t we get you home too?”

“Otay,” Trixie yawned. She didn’t want to admit it, but she was rather tuckered out. The little filly hugged her teddy, not even worrying if ponies see her in a diaper with her being too happy to care.

When Trixie got home to the overly pink padded library, Twilight was getting her charge ready for a nap, dressing her in a cute little purple sleeper.

Trixie was bouncing up and down in excitement, too giddy to stop as she chirped! “Hey, Twily! Did ya hear I went potty by myself?! I not gonna need diapees soon!”

Twilight placed a hoof over her chest and cooed. “Oh, I heard! You're growing up so fast,” The mare then pulled out the strange-looking alicorn amulet and continued. “Speaking about growing up, I think I can turn you back to normal now if you want.”

Trixie blushed, seeing Twilight had just revealed to her the amulet she spent all day trying to figure out. All that trouble, and it was all for nothing. But, the thing that nagged at Trixie’s brain now was this: Did she still want revenge on Twilight? Or maybe it was more than that; maybe she wanted to be a foal again. After all, she’d had so much fun doing things as a foal; it was an experience that couldn’t be replicated.

Trixie took a deep breath and said. “Wook....Twixie...dun mine being a baby fow a few more days, otay? Also, Twixie tinks ya should test it out more before ya use it on Twixie, just in case if ya make me younger.”

Twilight eyed Trixie, being a bit suspicious of her answer. “This morning, you were complaining about your diapers and now this? Are you up to somthing?”

“I’m not up to anything’, Twixie sure! And I wana do ta magic show tomorrow, otay?” Trixie responded rather suddenly. She knew that staying as a foal meant more embarrassment. But at the same time, Starlight’s utopia wouldn’t happen if Twilight had that amulet.

Twilight seemed not to notice the expression on Trixie’s face as she gave a nod. “Alright, well, I’m glad you decided on your own,” She then levitated Trixie into her crib and tucked the little foal under the blankets, plopping a pacifier into her mouth. Twilight kissed her charge on the cheek and whispered. “Ok, then have a nice nap.”

“Tank you mam-” Trixie clammed up as soon as the words left her mouth.

Twilight blinked looking rather surprise and asked. “What was that?”

“N...nothing, otay?!” Trixie cried out as she started to suckle her pacifier at a frantic pace. She couldn’t believe those words had come out of her mouth.

Twilight, however just gave a smirk and a nod before trotting to her desk to write to Celestia.

Trixie laid back, suckling her pacifier at a more rhythmic pace, unable to fall asleep. Why had she just called Twilight mama? She was not her mom! Now she regretted her decision and could only hope she didn’t grow too attached to Twilight.

Chapter Seven: The Sweet and Adorable Trixie's Debut!

The next day came much sooner than Trixie would've liked as she was now in the schoolhouse, sitting behind a makeshift stage. There were tons of props: A giant cardboard box, a sparkling wardrobe, and there was also a small mirror where the little filly was admiring her outfit. She was sporting a violet-colored frilly dress, a night blue-colored diaper with sparkly star and crescent moon sequins plastered over her padding. And to top it off, a little violet bow was tied into her mane. She just sat there, looking over how foalish she was becoming with her soft blue coat, a pout on her face to go along with her chubby cheeks, her stubby limbs, and large purple eyes.

The fact that she was a foal was something that was starting to remain concrete in Trixie's mind, and the filly had to admit she was, in fact, adorable. And as much as Trixie hated it, she could use her cute features to attract an audience. The filly thought about it for a moment. She then raised her hooves in the air, showing off her puffy padding, and squealed! "Check me out, Ponyviwwe! I Ta Sweet and Adowabwe Trixie!”

"What was that?" The little filly cried out in embarrassment as she turned around to face Twilight, now standing over her with a smile.

Trixie threw her dress over her diaper with her cheeks flushing pink and cried out. "Tat was nothin'! Trixie didn't say anything!"

Twilight lifted Trixie with her magic and let Trixie kick while she cooed. "Oh come on, I heard you," She then booped Trixie's nose with a hoof. "'The Sweet and Adorable Trixie' was it?"

Trixie groaned as she couldn't believe that Twilight had heard her say that out loud. "Just pretend ya didn't heaw anytin'!"

"Oh, I don't think so," The older mare snickered. She then took out a feather and started tickling the little filly as she watched her squirm about, kicking in her sparkly diaper and her adorable dress.

"Stop it!" Trixie giggled, unable to stop squirming about relentlessly in her crinkling pampers.

"Come on, say it one more time, then I'll stop. Or do you wanna pee yourself?" Twilight teased as she continued to tickle Trixie's chubby belly.

Trixie continued to giggle and squirm until she finally relented and cried out. "Otay! I Ta Sweet and Adowabwe Trixie!” Then the little filly squeaked, feeling a little pee come out, and she snapped. "Gweat, ya made Twixie pee!"

Twilight gave Trixie an apologetic look, then took a hoof and rubbed her charge's padded rump. "Oh, you just had a little tinkle, that's all. Nopony will notice." She then placed the filly down and helped smooth out her dress and bow. That's when Trixie noticed Twilight was wearing an outfit like Trixie had used to wear: A night blue cape with sparkly stars and a cone-shaped wizard's hat atop her head.

Trixie pointed her hoof at Twilight and asked. "Awe ya wearin' my owd outfit?"

Twilight looked herself over and shrugged. "I think it's akin more to what Starswirl wore, but yeah, sort of," She twirled about and asked Trixie. "So, what do you think?"

Trixie clapped her hooves. "Ya wook gweat! Too bad Spike didn't want to come."

Twilight eyed her charge and snapped. "Well, you did bury him in diapers."

Trixie looked up with those adorable puppy dog eyes. “Twixie did say she was sowie.”

Twilight went about fixing Trixie's dress once more before asking. "He'll come around, but for now, is there anything you need before we start beside a change?"

The little filly started to feel a little squeamish as she realized she was hungry, and she knew there was one thing that would help calm her nerves. She lowered her head and murmured, "Can Twixie have some of ya miwk? It...it helps me feel bettew."

This time Twilight was the one who ended up blushing a little and whimpered. "Well, of course. I... didn't realize you liked it so much."

"I dun! Is just ... it's good, tats aww!" Trixie whined.

Twilight giggled as she produced a small foal bottle filled with white foamy milk from the diaper bag on her side. She then sat down and cradled Trixie in her hooves. She adjusted the bottle and angled it into the little filly's mouth.

Trixie instinctively began to suckle on the bottle; the milk tasted amazing. The little filly turned her head and gazed into Twilight's eyes; she couldn't help but feel a sense of calm come over her. She held the bottle with her hooves and suckled until there was nothing left. Twilight then held Trixie over her shoulder, gave her back a few pats, and let her burp some spit-up.

The mare then placed Trixie down on the ground. "All right. Have you calmed down a little?"

Trixie nodded, smiled up at Twilight, and chirped. "Thank you, m-Twiwy."

The older mare placed a hoof over her chest at almost being called mom again, then cooed, "no problem, sweetie, now just relax and have fun. I'll let you know when it's time it shouldn't belong."

"Otay." Trixie chirped and waved a hoof. The little filly stood there, staring at her reflection once more with her face now a shade of pink. Everything was the same except for the fact that there was a little milk on her chin. And some of the wetness indicators on her diaper had faded. The strangest part about it, though, wasn't that she was embarrassed; it was that she was bothered by it at all.

An hour later, Trixie was still nervous as she sat behind the dark, violet curtains. Now she could hear the restless chattering of foals. She was curious at how many ponies had come, so the little filly peeked out and saw the classroom was completely packed with parents and their foals: Cheerilee standing in the back along with some parents and Twilight's friends, including Rarity, Fluttershy, and Pinkie Pie. The classroom wasn't the biggest venue, but there were still a lot of foals and older ponies in the crowd than Trixie had anticipated.

Twilight came over, bent down to Trixie's level, and whispered. "Are you ready?"

"Yeah, I weady." The little filly mumbled.

Twilight then trotted out on the stage, turned to face the crowd, and cleared her throat.

Trixie then went on stage and placed a hoof over her chest as she then proclaimed to the crowd. "Wadies and gentwecowts! I, Ta Sweet and Adowabwe Twixie is gonna show ya a show ya not eva gonna forget!"

Trixie beamed a smile, and she raised her hooves in the air as the crowd clapped and cheered. Some foals started to giggle, and others just dawwed. The little filly's cheeks flushed pink, knowing that her diaper was being shown off to the crowd of foals. If this were a few days ago, Trixie would be running out the door in sheer embarrassment.

But Trixie was starting to feel less embarrassed overall as the little filly shook those thoughts out of her mind. She then took out a wand and a top hat. Trixie trotted over to the front of the crowd, where she then raised her wand and twirled it around the top hat. "Now watch carefully! I gonna show ya my first twick, making a stuffed bunny into a weaw bunny!"

Everypony oohed as Trixie pulled out a stuffed rabbit, then slowly placed it into the hat. Then, the little filly waved her wand about as all the foals leaned on their seats, watching in awe. Trixie then threw a smoke bomb as she pulled Angel out from the hat! Everypony gasped in awe and clapped and cheered (Fluttershy was snickering as well). All the while, Angel kicked and whined until he was able to free himself and hop away.

The little filly then turned her attention to the crowd and bowed. She then raised her wand and chirped, "Now, fow my next trick! I gonna need a volunteer!"

Everypony was silent, but Zecora raised a hoof and chirped. "Wha bout me?"

"Yeah, ya do fine. Zecowa, come up hewe!" The little filly exclaimed as she waited for the zebra to come on stage. There, the two fillies hugged into each other's embrace. Then Trixie turned to face the crowd and squealed. "Otay, fow my next trick, watch as I magicwwy make Zecowa weaw my magic diapee!" The filly then took her wand and threw it over herself as smoke and fog covered the stage.

As the smoke dissipated, Zecora gasped, seeing that she now adorned Trixie's sparkly diaper. At the same time, the little blue filly stood there wearing only her dress and bow.

"Wha am I weawin' ya diapee fow?" Zecora cried out, now covering her padded front. "I dun need diapees! I keep tewwing I potty trained!"

The foals in the crowd all snickered as Trixie chirped. "Is a magic diapee, but tats not ta only ting tats magic hewe!" She waved her wand. With a cloud of smoke, Trixie's outfit disappeared, and it suddenly appeared on the zebra. As the smoke dissipated again, the crowd of foals burst into more laughter and dawws.

"Hey, why ya do tat fow?!" Zecora squeaked as she instinctively tried to hide her diaper with the skirt of the dress, which got a round of laughter from the foals.

Even Trixie couldn't help but snicker at seeing that her outfit didn't match the zebra's stripes at all (but she still looked adorable in it along with her poofy diaper). "Well, ta magic diapee has to have a magic dress! Dun wowwie, I've fixed it!" The little filly exclaimed. Trixie then twirled her little sparkly wand once more. With a poof of foal powder, the magic diaper was now around her rump along with her outfit, and the only thing left on Zecora was some foal powder around her backside.

As the smoke cleared once more, the foals all clapped and cheered, being somewhat amazed by the show while chanting. "Trixie! Trixie!"

The little filly was now wholly engaged in the show as she raised her hooves again. "Now fow Twixie's next twick, I'ww pwace Zecowa into ta box of time!"

Twilight trotted out from behind the curtains rather dramatically, throwing her cape up as the foals in the crowd oohed! The mare continued to push a cardboard box on top of some wheels until it was right next to Trixie. She escorted the zebra into the box and closed the small doors.

Trixie turned to face the crowd, and in a dramatic, mysterious tone, she declared, "Now watch as I move ta box, and swowwy tuwn Zecowa young!" She promptly did so, spinning the box left and then opened it.

Out popped a younger Zecora, all padded up in a new diaper that was a lot smaller to fit a foal her size. The baby Zebra looked down at her small pudgy body, seeming to be completely amazed. The foals gasped and cheered as Trixie bowed and nuzzled the younger Zecora. "See, she now back to a newborn foaw!"

Zero tried to speak, but only gibberish came out, making everypony dawww. Trixie giggled, and she couldn't help but tease her friend a little. "Can ya say, Twixie?"

"Taababa." Was all that Zecora was able to stammer out of her mouth, which got another round of dawws and applause. The zebra, however, got frustrated. She shouted at Trixie and started throwing a fit.

Trixie put a hoof to her mouth and snickered. "Uh oh, we bettew get hew back to nowmaw before she starts a super tantrum." That received a round of laughter, which prompted another round of Zecora's angry babbling.

The little blue filly then escorted her younger friend back into the box again. She then turned back to the crowd, threw her hooves up in the air, and exclaimed. "Now is time! I've to make hew grow olda!"

The foals in the crowd all clapped their hooves and waited patiently as Trixie spun the box around (this time clockwise).

This time, when Zecora trotted out, she was a lot older, appearing to be about the age of a school filly. Her cheeks were flushing pink as she looked around her body, completely surprised as she asked aloud. "This is so strange. Am I really a different age?"

Everypony just cheered. "Trixie!" once more in response as Trixie threw a hoof up. "Ya see? Ta box of time can town ya younger or olda!"

"Um, as fun as this can be, I wish to be a toddler, please." Zecora squeaked, closing her back legs and starting to do a small dance.

Trixie quickly recognized that it was a potty dance and then turned to the crowd. "Wight! Wet's get Zecowa back to her toddler years!" The blue-coated filly quickly escorted her friend back to the box. She started to spin it around to the left, and when she opened the doors for the last time, Zecora came waddling out. She now was back as a toddler with a regular diaper strapped around her rump.

Trixie raised her hooves and squealed. "Give Zecowa a wound of applause!"

Every foal in the crowd did as Trixie asked, clapping and chanting. "Zecora! "Zecora!"

The little zebra gave a few short bows, being a bit embarrassed about the diaper. However, Trixie could tell Zecora was relieved she was wearing one as she might miss the potty.

Applejack trotted over and quickly escorted her charge away.

Trixie then smoothed out her dress and took a bow. "Thank you, thank you. Now I gots one more twick before ta show is over!"

Twilight came trotting out, pushing the box away, and then she came out with a magical-looking cabinet. There Trixie came forward and bowed before the crowd. “Now watch as I, Ta Sweet and Adowabwe Twixie, wiww be pwaced in ta cabinet of mystwiews! I've been worked in with a pile of pwush animals!"

Everypony was on the edge of their seats as Twilight opened the cabinet, showing that it was completely empty.

Trixie trotted in and took another bow as the doors were closed. Every foal in the crowd waited in anticipation as Twilight opened the top and started to pour in dozens of plush animals. The foals all gasped, being somewhat scared that Twilight was burying Trixie alive!

Twilight then closed the top of the cabinet, held up an hourglass, and turned it around. "Now, don't worry, foals. By the time this hourglass stops, Trixie will be here safe and sound!"

Seconds passed as the sand filled the bottom of the hourglass. Then there was a loud "poof!" Then as the last of the sand filled the bottom of the hourglass, there was an explosion of what had to be foal powder, and Trixie stood at the foot of the stage covered in foal powder but with a proud smile on her face. The little filly threw her hooves in the air and exclaimed. "Ta Sweet and Adorable Twixie has arrived!"

Everypony clapped and cheered as every foal once again chanted. "Trixie! Trixie!"

Trixie raised her back legs and exclaimed! "Tank you aww fow coming to my show! And now, I must disappear as I used a lot of magic today!" She then threw a smoke bomb, and this time when the smoke dissipated, Trixie was gone, and everypony cheered once more.

A few hours later, Trixie was now back at the Golden Oak Library and was sitting on Twilight's bed. The filly was in a fresh diaper and her purple sleeper. The little filly was rather tired, yawning and stretching her hooves.

Twilight came trotting by and sat down next to her charge. "You were great today."

"Yeah, ya did a great job too... didn't think ya would use ta baby alicorn amulet," Trixie added, as that was something she knew had been added last minute.

Twilight snickered. "It was a great way to test it out some more. I couldn't believe how cute Zecora looked like a newborn. That reminded me how adorable she was when she first turned into a foal."

The little filly nodded. She sort of secretly wished they had kept Zecora as a foal, even as said. "Yeah, it would be cute if she stayed that way. But she just got potty trained."

"Yes, that's true; it wouldn't be fair to take that away from her. Also, great job on using that teleportation spell I taught you. I had to admit I was a bit worried." Twilight cooed as she nuzzled the filly.

Trixie gurgled a little, then started to bounce up and down on her padded rump. "Ya saw that! I got out before ya even put down ta first plushie!"

Twilight ruffled Trixie's mane and let her sit in her lap. The two sat there, nuzzled into each other as Trixie peered up and noticed that Twilight had bags under her eyes, also looking rather tired. She must've spent a lot of time trying to help find a spell to turn Trixie back to normal and assisted in making this magic show happen.

Trixie then asked. "Ya wook tiwed. Maybe we both can take a nap together?"

"Sure, why not?" Twilight yawned as she stretched her hooves, then took charge into them, and the two nuzzled together under the sheets. Trixie nuzzled right into Twilight's chest and placed her head into Twilight's soft, warm coat until she could hear her gentle heartbeat.

Twilight pulled the sheets up over them and popped a pacifier into Trixie's mouth as they nuzzled close together.

Before sleep overtook her, Trixie whispered. "Night, Mama…"

"Sweet dreams, my Sweet Adorable Trixie." Twilight cooed before yawning.

Chapter Eight: Meeting Jackpot

The next day started like how they’d mostly been this week for Trixie: She slept for almost half the day, had a diaper change (and then a bath), before being all dressed up in a fresh diaper and a purple onesie. The little filly was now having breakfast being spoon-fed foal oatmeal by Twilight. The mare in question was making faces as she went about spoon feeding Trixie foal oatmeal that was mixed with berries, and topped with some toasted brown sugar.

The little foal was in paradise as she continued to swallow down bite after bite of the foal food. Some of the clumps of oatmeal spilling onto her bib. She didn’t care as she was so relaxed and happy that nothing seemed to bother her anymore.

Twilight smiled at her charge as she continued to wipe her mouth and then continued to spoon fed her.

As Trixie was finishing the last of her breakfast ,she laid back in her highchair and thought things over for a moment realizing that within two days she’d probably be an adult again.

“Is something wrong?”

Trixie looked over to see it was Twilight who asked and shook her head. “No, Twixie’s fine.”

“I’m just asking, you seem quiet is all.” The mare cooed as she wiped down Trixie’s face.

“I just tiwed fwom yesterday,” Trixie said calmly, allowing Twilight wipe her face down. It was sort of true that she was still rather exhausted, but she also didn’t want to let the mare know how she was not looking forward to turning back into an adult.

Trixie then continued to chomp down the last of her foal oatmeal and after she finished eating Twilight wiped her face again then asked. “So Trixie, want to just go for a long walk around Ponyville? I bet a lot of foals want to see you after that show.”

The foal nodded as she was feeling a bit embarrassed. “Yeah, Twixie wouwdn’t mind seeing hew new fans.”She was then taken down to a changing pad and had her diaper changed (she was disappointed she wasn’t able to duplicate her potty training success) before being placed back in the stroller and strapped in.

Twilight looked Trixie over and then asked. “Are you comfortable?”

Trixie adjusted herself in the stroller in her crinkly diaper and replied. “Yeah, I fine.”

“Hmm, seems you're really enjoying being a foal.” Twilight commented with a smirk.

Trixie flashed her caretaker a shy smile and said. “Yeah, I am,” Then she asked. “Awe ya gonna test ta amuwet a wittwe mowe?”

“Of course I am, and when I'm finished will you be ready to turn back into an adult?” Twilight asked with a smirk.

Trixie bowed her head a little seeing that Twilight knew she was actually enjoying being a foal as she whispered. “I stiww unsuwe of tat. But suwe, as soon as ya make suwe ta amuwet wowks on unicowns, ya change me back to nowmaw.”

“Alrighty, cutie, just tell me when you’re ready to be a big pony,” Twilight teased.

“Haha, Twixie wiww be a big pony soon enough!” Trixie snapped back as she was pushed in the stroller out into the streets of Ponyville.

As Trixie was being pushed around the streets things started out pretty normal with her just hugging her plushie. She was surprised to be swarmed by a ton of foals all bouncing around her and shouting at the top of their lungs. “Sweet and Adorable Trixie! Sweet and Adorable Trixie!”

The little blue-coated filly waved her hooves, smiling back at her new fans. Some of the foals trotted over as they started to ask for autographs. Trixie threw her hooves over her face, too embarrassed to respond.

“Oh, this is just adorable! Come on, Trixie, just sign them.” Twilight encouraged.

“Fine, Twixie wiww, but she needs somethin’ to sign with.” Trixie grumbled. She was then hoofed a pink crayon and gave a grumble as she went about signing the papers with a crayon. Her cheeks flushed pink, looking down at her signature that just looked like illegible scribbles.

“Oh, don’t be embarrassed. You’re just a foal cutie,. Twilight encouraged and helped Trixie with her crayon singing. The filly also got a lot of compliments and dawws from parents with many asking if Twilight was going to adopt her. When those conversations started to crop up Twilight quickly pushed the filly down the road, escaping the crowd of ponies as they headed home. That was when the two both spotted a strange blue-coated stallion.

The mare cocked her head a little, being rather surprised by the stallion and whispered. “Hey, Trixie, that stallion looks a lot like you.”

“Yeah, he does…” Trixie whispered, rather surprised by seeing this strange pony as well. He did look similar to her with the same mane color, eye color, coat color, he even dressed like a show pony: Sporting a mellowed yellow top hat, along with a snazzy purple suit with an expensive blouse and a snazzy purple bowtie.

Trixie didn’t recognize him immediately, but her eyes went wide as she remembered pictures of him! It was her dad who’d left her and her mother when she was just a foal and then her surprised expression turned into a scowl. “He’s nopony, wet's just go.”

Twilight looked down, rather surprised by her charge’s reaction. But she decided not to press, figuring Trixie had a good reason. “Ok.” She then continued pushing Trixie down the street as Trixie hugged her plushie close to her chest, still seething with anger.

Why was her dad here after all these years? Was he after bits? Maybe he was here because of her silly show? Whatever the reason, she wasn’t going to give him anything.

When both unicorns were now back at the library, Trixie was placed back in her playpen as she was busy practicing, using her horn to levitate her plush animals.

Twilight sat down in a chair going over some notes on the amulet, ready for more practice with it. Then they heard a knock at the door and the two both looked over at it. Twilight then slowly opened it and was surprised to see the mysterious stallion from before standing in the doorway.

The blue-coated stallion tipped his top hat. “Good afternoon, mam. I hope I’m not intruding.”

“No, not at all. But, who are you?” Twilight asked.

“My name is Jackpot! And I'm here to see my daughter Trixie!” Jackpot exclaimed with a triumphant smile.

Twilight looked the stallion over with a smirk. “I can see the family resemblance but I need to confirm it,” Twilight turned to her charge and asked. “Hey Trixie, is he really your dad?”

The little blue-coated filly narrowed her vision, glared at the stallion across the library and snapped. “Yeah, he’s my dad.”

Twilight either didn’t notice or didn’t seem to care about the glare as she told the stallion. “Alright. Come on in, Mr. Jackpot.”

“Don’t mind if I do, madam!” Jackpot then trotted across the room and headed right over to the little filly, staring at her wide-eyed while Trixie just continued to glare at him.

Twilight looked between the two and could sense that it was best to leave. “I’m just gonna leave you two alone. If you need anything, I’ll be upstairs.” The unicorn then quickly trotted up the stairs leaving the two.

Jackpot then lowered himself down to his daughter’s level and whispered. “My goodness, seeing you like this feels like I’m stepping back in time…”

“Yeah, guess so seeing I dun know anythin’ bout ya,” Trixie snapped. “All I know is ya weft me and my mom.”

Jackpot lowered his head and grumbled. “Yeah, I did. And I apologize. I, um…”

Trixie threw her hooves across her chest, she didn’t care what his reason was! He’d left her and her mom penniless and with her mom working her rump off to care for her! She then snapped back, “I dun cawe why ya weft! And honestwy, I dun even know why ya came hew!?”

Jackpot rubbed a hoof into the ground as he replied. “I came to see if I can um...be a father again is all.”

Trixie continued to glare at him and growled. “Now, aftew aww tese yeaws? Ya just come ovew because Twixie is a foaw now?”

Jackpot shrugged. “Yeah...I...I don’t know. I thought we could rekindle our relationship and I could try being a dad for real.”

“How did ya know I was even hewe? Did ya heaw bout me fwom my show yesterday?” Trixie asked.

Jackpot couldn’t help but boop his daughter’s nose. “Yes I did, and I heard you were rather adorable.”

“Ok, tanks. Too bad ya didn’t come to my dozens of othew shows, just ta one when I’m a foaw.” Trixie bitterly snapped back.

Jackpot brushed a hoof over his mane. “You are not making this easy, Trixie.”

“Me?!” Trixie growled! “Ya ta one who weft me fow aww my wife, and now ya come to me when I a foaw again!”

Jackpot stepped back. He just now seemed to realize that his daughter was rather hurt.

Trixie sighed, she was trying not to be mean but she couldn't believe the gall her father had to think she’d just forgive him after all these years just because she was a foal. “Wook, just cause ya come ova to see me as a foaw tat doesn’t change anythin’.”

Jackpot bent down. “Can I at least try to make it up to you, even just for one day?”

Trixie grumbled under her breath, wanting to say no. But seeing and realizing that this might well be the only chance the two would have to bond, she relented. “Fine, we can bond. What ya want ta do first?”

“I...um...wouldn’t mind changing your diaper. I mean, you do want to be changed, right?” Jackpot questioned.

Trixie looked down at her padding, saw it was sagging and sighed. “Fine, ya can change my diapee. If ya know how.”

Jackpot then placed the filly down on the changing table, removing the little filly’s diaper slowly as Trixie giggled. “Been a whiwe, huh?”

“Yes, it has,” Jackpot admitted. “I can’t remember the last time I even touched a diaper, let alone changed one.”

Trixie gulped, worried her father would mess it up somehow. “Maybe, we shouwd get Twi-”

“-No, I got this! A diaper is no match for the Great and Powerful Jackpot!” Jackpot responded as he slowly untapped the diaper and then began to wipe Trixie down. He was going to strap her up in a new diaper, but the filly threw up a hoof. “Hey, ya fowgettin somethin’!”

“What?” Jackpot asked, looking genuinely confused.

“Ta foaw powdew. Ya dun want me gettin a wash, do ya?” Trixie explained.

“No I don’t.” Jackpot replied, took out a container of the powder and lightly poured it onto his daughter’s rump. Afterward he then strapped her up in a new diaper, and then stopped as he tried to find the tail hole.

Trixie snickered. “Daddy, thewe’s a hwle in ta back. Just puww my taiw thwough.”

“Ok, I got it,” The stallion irritably grumbled as he nevertheless found what he’d been looking for. He then pulled the tabs of the diaper over Trixie’s front. She looked down to see that overall it was good even if the diaper was a bit lopsided. Jackpot adjusted the diaper for the filly and then trotted across the library as he waved a hoof. “Come on, trot to me.”

Trixie plopped down on her crinkly tush. “Oh weawwy? Ya want ta see me twot?”

“Of course! Come on, do it for me. Please?” Jackpot asked with a smile.

Trixie rolled her eyes as she rose up on her hooves and trotted across the library, giggling as the fresh diaper gave her a cute waddle. She trotted right up to the stallion and Jackpot took her up in his hooves. He then placed Trixie down in a playpen and asked. “Why don’t you show me some of your magic?”

Trixie shrugged. “Otay, I dun see why not.” She then lit up her horn, then started to maneuver the blocks with her horn and stack them on top of each other. It wasn’t as much as a struggle as it was a few days ago. So she was able to stack the blocks into a tower.

Jackpot clapped his hooves together and cheered her on. “Great job, Trixie! I’m so proud of you! You’re my little girl, alright.”

Trixie didn’t want to admit it but she did feel rather happy at her dad being supportive. But the pang of hurt from him being gone from her life for so long was always on the back of her mind. She wanted to get past these negative emotions, but they lingered regardless of what she did. The little filly then felt her tummy rumble. She was rather surprised seeing as she’d just eaten not too long ago. “I guess I hungwy now.” She commented.

“Must be from using so much magical energy. Come on, sweetie,” Jackpot explained as he lifted her up into his hooves. He then nuzzled her belly as she kicked about in her crinkly diaper.

Trixie kicked and gurgled just like a foal unable to help herself while being tickled.

Jackpot then sat down in one of Twilight’s loveseats, and hoisted a prepared bottle right into Trixie’s mouth. The little filly grasped the bottle and suckled the contents gently, staring right into her dad’s eyes. She could see the stallion was tired and worn and wondered how much he’d traveled like she used to do just to get by.

Jackpot soon removed the bottle with an audible “pop”, and Trixie burped before asking. “Daddy, I gots to ask. Why did ya weave me and mom?”

Jackpot gulped. He seemed hesitant to explain, but eventually he gave a long sigh and confessed. “The truth is... I couldn’t support you. I was broke and had nothing when I married your mother. You came along rather suddenly...I...I thought I could make a living to support you and your mother at Las Pegasus, working as a stage magician. But your mother wanted to stay in Vanhoover where you were born because she was close to family. I had to choose between a promising career or staying with you.”

Trixie was silent while Jackpot teared up a little as he continued. “I chose to go to Las Pegasus. And I did send bits to you and your mother, but she would always send them back to me. It didn’t take long for me to realize that I’d chose wrong and I didn’t think you or your mother would ever forgive me. I was too prideful and ashamed to come back or come looking for you.”

Trixie wasn’t surprised by the story, her mom had been stubborn and wasn’t always completely in the right. But that didn’t excuse Jackpot for ghosting her all her life. She might not ever really see Jackpot as her father, but at the very least now she felt willing to start forgiving him. “Otay. I fowgive ya now. But when I tuwn into an aduwt again, we gots a wots mowe ta do befowe we can weawwy have a wewationship.”

Jackpot gave her a smile as he trotted upstairs to tuck her in for a nap. “Alright, it’s a deal.” He kissed her on the forehead before trotting off as Trixie laid her down in her crib, wondering if she can ever really forgive him. Deep down he was almost like her: Selfish and arrogant to a fault. But he’d seemed willing to change and deep down she was realizing she was becoming just like how he was. She’d almost destroyed all of Ponyvillle by unintentionally getting that Ursa Minor woken up with her lies (albeit indirectly). And then she’d tried to get her revenge using some dark magical artifact.

The filly paused realizing that she was working with Starlight to destroy Twilight, the one pony who had cared for her and had worked tirelessly to make sure she was turned back to normal.

Trixie slammed a hoof into her face! “Ugh! Wha am I tinking!? I need to stop Stawwight!”

Just then Twilight slowly trotted over. She peered over the crib and asked. “So, Trixie, how did your time with your dad go?”

Trixie looked up into the unicorn’s eyes and replied. “It went fine, we tawked and I sowt of fowgive him fow weaving me as a foaw, but it’ww take time.”

Twilight nodded and then Trixie turned towards her and whispered. “Wook, Twiwy, tank you fow cawing fow me. Ya...ya a good mommy.”

Twilight placed a hoof over her chest as she teared up a little. “Thank you, Trixie. That means a lot to me. Now, do you need anything before you take a nap?”

Trixie gulped as there was one last thing she wanted to do. “C...c...can Twixie nuwse fwom ya? Just one time.”

Twilight just gave a slight nod as she laid down on her bed. She then used her aura of magic as she drifted Trixie over down to her teats.

The filly then gently took the right teat, placed her mouth around it then began to suckle out the sweet, warm milk. It was such a lovely sweet taste as it flowed through her mouth, and she was in complete and utter bliss. The little filly nuzzled into her, closed her eyes and slowly drifted off to sleep.

Chapter Nine: Showdown between Trixie vs Starlight

A few days passed after Trixie's father came to visit her, and the little filly was laying in her crib staring up at a mobile slowly swirling overhead. She woke up and couldn't seem to go to sleep the next day, realizing that this was the day she was supposed to be betraying Twilight. But she was coming to a realization she'd be taking on Starlight and keep her from taking the spy teddy from her at all costs. The little blue-coated filly was still too nervous to tell Twilight the truth as their relationship had grown a lot since her father's visit.

Trixie could feel that she had soaked her diaper once more, and she usually would whimper a little or something like that to wake Twilight up to change her. Curious about what Twilight was doing today; however, Trixie just got up on her hind legs while showing off the adorable violet sleeper.

The baby unicorn then looked over, seeing that Twilight was fast asleep this morning, and she realized that her caretaker hadn't slept that much this week. Trixie didn't want to wake her up. So she buried herself under the covers and started to suckle on her pacifier as she thought things over.

Trixie laid in her crib suckling away as she was starting to feel guilty for everything she'd done up to this point: Lying and spying. The little blue-coated filly was now focused on thinking about what she wanted. She took out her spy teddy and asked out loud: "Does Twixie want to stay a foaw? Ow shouwd Twixie westawt hew wife with Twilight being hew mommy?" Of course, her teddy didn't say anything back, but she was starting to groan as she realized something. "If Twiwy finds out I betrayed hew, ten she gonna have me turned back to nowmaw and ten have me banished fwom Ponyviwwe!"

Trixie then plopped back down on her padded rump and started to suckle away on her pacifier, thinking things over a bit. Then out of nowhere, an idea suddenly came to mind as she looked back at the teddy and shouted out loud. "So that means I just gotta beat Stawwight and keep Twiwwy fwom finding ya! Ten Stawwight gots nothin!"

That would mean Trixie would need to dispose of the teddy bear before Starlight comes back…." Sowie, teddy. I hope ya dun have had feewings, but if Stawwight gets hew hooves on ya, a lot of ponies wiww get huwt."

Trixie then took the teddy and hugged the plushie close to her chest while she cried. "I sowie. Tis aww my fault, but ya gots ta go!"

She lit her horn and took the teddy with her magic. Trixie grunted, doing her best to charge her horn with as much magic ability as she could muster. With tears in her eyes, she surged a wave of electricity through her horn and hit the teddy, setting it ablaze! The little filly sat there and just watched as the teddy bear was engulfed in flames as it slowly smoldered into a pile of ash. Trixie's face was now in tears as she stammered. "Sowie, spy teddy…." She then used what little energy from her horn to poof the ash into a puff of smoke; that way, there was no evidence.

Trixie wiped the tears from her eyes and then laid back down in her crib. "Weww, now there's no mowe spy teddy. Now I just gotta face Stawwight and keep hew fwom finding Twiwy's amuwet."

Later that morning, Twilight went about her day: Changing Trixie's diaper, feeding her, and then watching her practice magic by stacking blocks on top of each other. Twilight noticed that the filly had less struggle than she was a few days ago. But she looked somewhat exhausted for some reason, making a mistake here and there. And there was something else too.

"Hey, Trixie," Twilight commented. "I noticed your favorite teddy is gone."

"Oh, um...Trixie must've wost hew teddy. It's otay; I gots wots more stuffed animals." Trixie explained rather nonchalantly.

Twilight found that answer rather suspicious. She'd seen the little filly take that teddy everywhere. And now she suddenly didn't care that she'd lost it? "Alright, just curious is all," She said, at last, deciding not to press on the matter. She then trotted over to Trixie and asked. "Now, I know that you like being a foal; that much is obvious. But you should know that I tested the amulet on Rarity yesterday, and it worked perfectly."

Trixie paused as she stacked the last of her blocks on top of each other then looked over at Twilight. "C..can I wait until tomorrow? I just wana to be a foal for one more day."

"Ok, that's fine with me." Twilight cooed. She then sat down next to her foal and ruffled her mane. Trixie nuzzled into her, then pointed downward, and Twilight nodded. She knew that she was hungry.

Trixie once again held onto one of Twilight's teats and suckled away, enjoying the warm milk flowing down her throat.

Twilight, meanwhile, was thinking that tomorrow she'd ask if she wanted to stay as a foal. The thought has crossed her mind multiple times over the week, and the truth was she wasn't sure if she was ready to be a full-time mom. True, she'd taken care of Celestia and Luna and her brother and his wife. But being a mom for years, she wasn't sure she was ready for. But seeing Trixie, Twilight was confident of her potential in magic. She might not have the raw talent Twilight had had as a foal. Still, she made up for what Trixie lacked in ability; in determination.

Maybe if Trixie were raised upright, she would be even greater at magic than she was before since Trixie would be surrounded by ponies who'd support her.

Twilight laid her head down and relaxed, letting her foal continue to suckle from her teats. Maybe she could make a real difference in Trixie's life by having her grow up here in Ponyville.

Later that evening, Twilight and Spike were fast asleep once more, and Trixie was wide awake. Her heart was thumping in her chest. She then turned to see Midnight fly through the window, and she threw her mane with a smirk. "So, Trixie, ya weady?"

"Y...yeah…" Trixie stammered as she teleported herself out of her crib. They both slowly trotted downstairs.

There they came upon Starlight, who was still a foal. She was sporting a poofy diaper, along with a cape around her neck and a scepter in her hoof. "Hewwo Twixie and Midnight, ya weady to be big ponies again?"

Trixie gulped, seeing that this was it. She'd already made her decision to betray Starlight when she'd burnt her spy teddy. So now she had to only take her own and show her resolve. "Sowwie, but ya faiwed! I buwned ta spy teddy!"

"What?! Ya serious?! Why would ya do tat?!" Midnight cried out.

"Because I weawise we awe wong!" Trixie insisted. "Tuwning ponies into foaws against thiew wiww is wrong! And I think we need to stop tis wight now!"

Midnight gnashed her teeth and shouted! "Sweiouwsy?! She was ta onwy way we gonna tuwn back to normal!"

"I don't care! I'm gonna be adopted by Twilight and wive my wife hewe in Ponyviwwe, so ya can buzz off!" Trixie snapped with a smirk on her face.

Starlight just stood there, then burst into a fit of laughter and clapped her hooves. "Sowie, I should've been more specific; I know exactly what ya did aww week. I've been watchin' ya and tats why Midnight became my twue spy."

"Huh?" Trixie turned to see Midnight with a smug grin as she pulled out a plush rabbit.

Midnight explained. "I saw how ya acted at tat magic show and weawised ya was wiking being a foaw too much."

Midnight then threw the rabbit to Stralright, who snickered. "We both also know tat Twiwy has an amulet...or I shouwd say had," Starlight then pointed at her staff, revealing that the amulet was on top of it. "So wike it ow not, ya gonna be a foaw fow a wong time!"

Trixie cursed herself as she saw that Midnight and Starlight had tricked her! The blue-coated filly realized that she indeed had done nothing in keeping Twilight and her friends safe. What's worse was that she probably should have warned them. But her fear of being discovered as a spy had made her weary, and now it may have cost them everything!

Suddenly, feeling a sense of determination, Trixie stomped her hooves. "Put ta bunny back in my toy box!"

"What?!" Starlight asked, being somewhat stunned at Trixie's response.

"I said put ta bunny back in my toy box ow ya gonna get it!" Trixie shouted! She then planted her hooves into the ground and lit up her horn.

Midnight burst into laughter. "Get hew, Stawwight! Put hew back in Twiwy's tummy!"

Starlight smirked. "Good idea, that way it'ww give us time to defeat ta west of hew fwiends and keep hew shut!" Her staff then lit up as energy shot out from it!

Trixie did her best to jump around, dodging the blasts of magical energy being shot at her! Some residue of one must have hit her as she felt herself shrink a little. Trixie then ran behind a coach and hid there to catch her breath. "Gotta be careful!"

Starlight was right behind Trixie, chasing her as she shouted! "Ya, get back here!"

Trixie gulped as her forehead began to sweat, realizing that she should be shouting for help! But then Twilight would know of her betrayal!

Then, an idea came to Trixie as she took out a plush Ursa Minor left behind from earlier and used her magic to set it up with a small cone block on top of it. She smirked, seeing that she could (hopefully) have Starlight use her magic at the plush bear while taking the opportunity to take the staff! She then went under the chair and then waited for Starlight to come around.

The little grayish-purple coated filly trotted over as she looked over at the plush. Trixie smirked, seeing the filly's horn light up and send magical energy towards the plush animal. But nothing happened. Trixie then flew out of the couch and sent her padded bottom right into Starlight's face, throwing the filly off as the staff flew across the room as the bunny plopped down!

Seeing Starlight dazed, Midnight flew towards the two.

Realizing her limited options, Trixie ran across the library and snatched up the staff!. She then turned to see Midnight grab the bunny and lift Starlight up. Trixie aimed the staff at the two. "I know that this is the awicorn amuwet. I feel the same magic as before, so I can easily tuwn ya both even younga!"

Starlight cursed as she shouted! "Fine, keep tat stupid staff! But we got aww ta info we need to take ya and you fwiends down!" She then lit her horn, and the two other foals suddenly disappeared.

Trixie smirked and started to bounce up and down, being excited that she had taken the staff!

But now Starlight had all that information, plus Midnight had rejoined her!

"Trixie, what's going on?" Trixie turned to see Twilight trotting downstairs, and Trixie stood there with the staff in hoof as she sighed. "Twilight wet me explain."

It was now early the following day. Despite getting almost no sleep, Twilight was astonished by Trixie, who explained everything about the spy teddy, Midnight's betrayal, and having her learn about her friends through the friendship lessons.

It took a few hours, but Twilight nodded, "Right...it seems Starlight is able to still travel through time. But it seems she can't go back in time twice. If she did, she could easily go back in time to that confrontation and just take Midnight and leave. But seeing that we still have the amulet, I would say we're fine."

Trixie was starting to tear up as she was now scared that Twilight was going to banish her. "I...I sowie. I know ya can't forgive Twixie, so before ya banish me at wears wet me say bye to Zecowa!"

Twilight then slowly trotted over and hugged Trixie. "Banish you? I can never banish you! As much as I wish you'd just told me the truth, you not only decided to go against Starlight, you risked yourself in the process. If you did call for help, I may have underestimated Starlight, and she could have turned me into a foal. But she didn't expect you to be so cunning. You took advantage and got the amulet back."

Twilight then placed a hoof on the amulet around her neck. "Now we have the amulet secured. And even if Starlight has all that information, we can always change our friends back to normal as long as we have this," She then bent down to Trixie's level and faced her. "But now we have one more thing we need to discuss. Do you want to return to normal, or do you want me to be your mother?"

Trixie gulped and scrunched the diaper between her legs and whimpered, "T...Trixie wants ya to be my mommy…."

Twilight started to teared up, and then in a burst of emotion, she reached out and hugged her foal close to her chest as she cooed. "Alright, it's a deal. But from now on, I will be much stricter; I have to make sure you grow upright. And on top of that, you're going to be punished for your deceit."

"Oh, what sort of punishment?" Trixie nervously asked.

Twilight smirked as she then began to tickle her filly's belly and cooed. "We're going to throw you an adoption party, and I want you to perform your adorable magic again!"

Trixie squealed in laughter, kicking about as she shot Twilight a smile. Being a foal again meant she could try once again to be a part of Princess Celestia's School for Gifted Unicorns, and maybe this time, she could pass her initiation! It also meant she could have awesome friends like Zecora! And as long as she was by Twilight's side, she'd do her best to protect her new mommy and make up for her mistakes.

Chapter Five: Rainbow Dash's Babysitting woes

Later that evening, Twilight woke up to find she was in a crib again with the plastic bars surrounding her. This wasn't the first time this had happened to her as she instinctively looked down at her body to see that she had pudgy hooves and a small, chubby form.

Twilight trembled, realizing once again she was regressed into a foal. As if to verify one more thing, she threw the blankets off her body and revealed her rump covered in a thick, fluffy diaper. This solidified what Twilight feared as she slammed her hooves over her face and roared. “Not again! Who tuwned me into a foaw tis time?!"

“Don’t worry, Twilight, you're not actually a foal,” Twilight gasped upon hearing that it was Princess Luna who spoke. She looked up to see the princess of the night flying down towards her with a little smile on her face. Princess Luna landed right next to the filly and nuzzled her as she whispered. “I apologize; I didn’t expect this dream to be so... adorable.”

Twilight looked around, seeing the cute nursery with stars all over the room as she then whispered back. “Yeah, guess I enjoyed being a foaw a wot mowe ten I wealized," She looked down at her diaper, seeing that it had Luna’s cutie mark on it and blue leak guards. The familiar feeling of the diaper being snug around her rump was rather comforting. “This is a rather cute dream.”

“Yes, and I have to admit, I'm rather flattered you took a liking to my brand of diapers,” Luna cooed as she gave the padding a few pats. “However, that's not the only reason I brought you here,” The princess of the night explained as she showed Twilight an amulet. It looked rather similar to the Alicorn Amulet, but this one had a cute look, with the outline being a baby alicorn with tiny metallic wings springing out from it.

Twilight’s eyes lit up, and she held out her hooves, batting the amulet a little due to being enticed by it.

Luna snickered as she nuzzled the little filly and as she explained, “This is a copy of an amulet my sister and I created, and we want to show it to you and your friends. However, we don’t trust Trixie.”.

Twilight got control of herself, shaking her head to concentrate on the princess in front of her. “Right...I mean, she did come back to Ponyville to try to take revenge. I can understand not fully trusting her. But what does the amulet do?”

Luna placed Twilight down and continued to explain. “It enhances the ability to perform age spells. But we have only tested it on non-living objects, and we are unsure if it can reverse the regressions. You said that Starlight Glimmer is still out there somewhere?”

Twilight waddled about the nursery, secretly enjoying being in diapers again, even if it was just a dream. Just the feeling of the padding around her rump made her feel relaxed. She then plopped on her padded rump as she took a bottle, plopped it into her mouth, and suckled on it while enjoying the formula. As she finished her bottle, she looked over at Luna, who then giggled and asked again. “Did you hear me?”

“Oh yeah, sorry,” The unicorn with a light purple coat squeaked, feeling somewhat embarrassed at her foalish instincts took over as; she got up on all fours and continued. “Yeah, I did. That means we have to be prepared. From what I've heard, she's gone through time and regressed ponies in the future.”

“Right, which is why we made this amulet. Regardless of how they were turned younger, this amulet will hopefully reverse the effects of age regression.” Luna replied. She then scooped up the little foal and took her to the changing table.

Twilight squeaked, seeing her dream diaper was soaked. The worst part was, she hadn't noticed at all! “Eep! This isn’t real right!”

“Of course not; it’s just a silly dream,” Luna cooed as she started untaping the diaper and began cleaning Twight up. The princess of the night nuzzled the filly and whispered. “Just think of it as returning the favor for caring for my sister and me.”

Twilight cheeks flushed red, too embarrassed to say anything as she let Luna finish the diaper change. The little filly giggled and gurgled as she kicked about, and the princess laid her back in the crib. “Now, just remember when you wake up to come to Canterlot and visit us. But for now, go on and get some sleep, little one.”

“Alright.” The filly yawned as she snuggled under the covers and drifted off, hoping she had this same dream the following night.

The following day, Trixie was enduring another day as a foal in her playpen. She was keeping herself busy, trying to levitate blocks with her horn and practice teleporting them.

Spike was still angry at her for what happened yesterday as he sat in the kitchen, chomping on his gems angrily while glaring at her.

Trixie just stuck her tongue out and continued concentrating on the blocks. As she floated the blocks about, she mulled over her situation. She realized that she only had four days left to give Starlight some information about the mane six, and all she’d learned so far was that some bats were sucking the juice from apples at Sweet Apple Acres.

Trixie could be foal for months, if not a year, from the sounds of Twilight’s progress in a cure! That meant Trixie’s only real option to turn back into an adult was to give Starlight somehow what she wanted. But to do that, Trixie needed better information.

“Spike, we have a problem!” Trixie heard Twilight shout as she came running downstairs! The unicorn then turned to her assistant and continued to explain. “We need somepony to babysit Trixie, now!”

“Not me!” Spike snapped, throwing his claws up in protest.

Twilight rolled her eyes. “Yeah, like I would trust you with a baby. Besides, you’re coming with me,” She then turned to Trixie and explained. “Look, last night Princess Luna said she might have found something promising about age spells to turn you back to normal. But she wants Spike and I to meet her in Canterlot and for you not to come along.”

“Tats fine with me, but it wooks wike ya need to find a babysittew,” Trixie mumbled, trying to act like she didn’t care. But she kept her ears perked up, thinking that there could be more news as to what Celestia and Luna discovered.

Twilight started to pace back and forth. “Yes, we’re going to need a foalsitter for you, Trixie, but…”

Spike shrugged. “Everypony we know has foals now. We can ask one of them to watch her. Maybe Applejack, Fluttershy, or Pinkie Pie?”

Twilight sighed, rubbing a hoof over her face. “If only, but they have their foals and responsibilities...I could ask Applejack again….”

Pinkie Pie then came bursting in with a pair of familiar changeling foals on her back as she asked. “Hey, can you do me a favor and watch the changelings for a few hours? I was told I was needed in Canterlot.”

Twilight blinked, looking somewhat confused, and asked, “you too?”

“Yeah, guess Luna said something about an emergency.” Pinkie explained as she placed the baby changelings in the playpen next to Trixie.

The little unicorn filly eyed the two and waved a hoof as the changelings nervously waved back.

Then following close behind her, Applejack came along with Zecora in tow. “Huh, y’all got the same message?”

“It seems so,” Twilight mumbled.

Zecora, meanwhile, ran over to Trixie, who smiled at her new friend. “Hey Twixie, how ya doing?”

“I’m fine...tough I focusing on using my magic and not going to ta potty wight now.” Trixie admitted as her cheeks flushed red.

The other foals snickered as Zecroa threw up a hoof. “Is fine, being in diapees are comfier anyways. I wanna go see if Twiwight gots some cool potions. Ya tink it would be ok if I go upstaiws?”

Trixie giggled, seeing that Zecora’s mindset was that of a toddler, and seeing that the adults were distracted. Plus, to her, it would be a great little prank on Twilight to have Zecora mess with her stuff. “Yeah, go ahead and have fun. But be cawefuw, dun make anything too dangeouws.”

“Otay!” Zecora squealed as she ran upstairs when nopony was looking.

Rarity came through the entrance with her little colts a moment later. Looking around at her friends and the rest of the foals, she just sighed. “Oh dear, it seems we all were called to go to Canterlot today.”

Fluttershy slowly walked behind Rarity with Midnight and Discord in a stroller with a pink diaper bag strapped around her midriff. She buried her head under a wing and stammered. “Same as me...whatever is going on must be important."

Rainbow Dash flew in soon afterward, seeming to have noticed the commotion and exclaimed. “Hey, am I the only one who didn’t get the message?! What's going on?!"

Twilight was still somewhat confused herself, and she didn't know how to explain what's going on. But she wanted to reassure her friend that it wasn't anything too serious, as she explained to the best of her ability. "It's ok, Rainbow Dash. Princess Luna just gave us a message that she and Princess Celestia have created something that could possibly help with the age regressions."

"Wait, you mean that's it?! I was hoping it was a summon for another monster to beat up." Rainbow Dash irritably grumbled, clearly disappointed by the news.

“That’s good and all, darling, but we still have one issue we need to address,” Rarity pointed out as she looked over to the playpen. “Who will care for the foals while we're gone? We need someone to do it."

Everypony looked at each other with nervous looks as Rainbow Dash flew up and exclaimed. "It's going to be me, of course! I didn't get the message, so obviously, Princess Luna and Princess Celestia want me to babysit."

Twilight shook her head, sensing that leaving all the foals with Rainbow Dash would be a terrible idea ."We can’t leave you with all these foals for a day! That's crazy!”

Rainbow threw her hooves across her chest and scoffed. “Oh, come on! I can totally handle a couple of foals! You all make it look so easy."

Rarity rolled her eyes. “Darling, do you even know the first thing about taking care of foals?”

“Yeah! I’ve helped all of you once in a while!” Rainbow shouted back!

“Playing with them, not necessarily caring for them,” Fluttershy whispered.

But the daredevil mare threw her hooves up and replied. “I can care for them; how hard can it be? Change some diapers? Make sure they're fed? Have them in bed by eight? Easy peasy if you ask me.”

Pinkie Pie snickered, sensing that Rainbow was just like her when she’d cared for the Cake Twins for the first time. “Oh, I'm sure it’ll be fine! Rainbow Dash can handle anything, and she never gives up!” She exclaimed while making notes to set up a hidden camera.

Rarity turned to her colts and eyed them. “Well...if it’s coming to that, I expect you two to behave yourselves and help Rainbow Dash care for the other foals. Understood?"

“We will!” The colts cried out as they hugged Rarity while she kissed them on the forehead.

“You two better behave as well, no using any kind of magic while I'm gone." Fluttershy scolded her charges.

Discord saluted her. "Don't ya worry, we be good! I’ll keep an eye on Midnight."

"Oh yeah!? Is more wike I'ww be keepin' an eye on ya!" Midnight snapped back.

The two began to argue, but Fluttershy would have none of it, flaring her wings up. "Both of you, stop!" Both foals stopped immediately as she lowered her head to their level. "Behave, alright? If I hear any of you causing any trouble, you'll be grounded for a week. Do I make myself clear?"

"Ok." The two mumbled as Fluttershy threw them into a hug and nuzzled them.

"Just play nice and listen to Rainbow Dash,” Fluttershy concluded. “She's in charge now." She then placed the foals into the playpen next to Trixie, who eyed the two with a suspicious look.

Twilight just stood there, shaking her head. “This is a bad idea; we should get somepony else to help, like Big Mac or Cheerilee. Doesn’t anypony else agree with me on this?”

Rainbow Dash rolled her eyes. “Oh, stop worrying. It's only going to be for a few hours, right? What’s the worst that could happen?”

Twilight pointed a hoof, shoving it into Rainbow Dash’s snout as she shouted! "Don’t say that! Don’t ever say that!” But it seemed that despite her misgivings, she might not have a choice. So she reluctantly relented. “Fine, we’ll leave the foals with you, Rainbow Dash. But I still think this is a terrible idea,” She looked over at Trixie and gave her a stern look.“You think you can behave yourself while I'm gone?”

“Of couwse, Twiwight!” Trixie squealed.

Spike got up and walked over to the others. “Well, I’m coming with you girls. I’d rather not get buried under diapers again.”

The rest of Twilight’s friends couldn’t help but burst into laughter as Twilight then led everypony except Rainbow Dash out of the library.

As soon as her friends left, Rainbow Dash walked over to the foals and glared at them. “Alright, you little troublemakers, I'm in charge! That means we're going to play a game of hiding and seek.”

“Ok!” The foals all squealed in unison, and almost every foal ran off to hide as Rainbow stood there and shouted, “Hey! I didn’t even start counting yet! That’s not fair!”

Every foal was now looking for a place to hide somewhere within the library, except for Trixie and Midnight. The mysterious alicorn foal flew into the playpen next to Trixie. “Hewwo! Can I pway with you?”

“S...suwe…” Trixie stammered, looking over at the baby alicorn suspiciously. She only vaguely remembered the newspapers claiming an evil enchantress named Midnight was the one who was turning ponies into foals a few years ago. And from what she remembered, Midnight was the one who’d turned Prince Blueblood into a colt (and for a little while into a filly).

“So, what’s ya name?” Midnight asked as she helped stack one of the blocks.

Trixie paused. She’d heard that Midnight and Starlight had at one point teamed up, but she felt it would still be wise to befriend this alicorn since more allies couldn't hurt. She took out a hoof. "My name is Twixie."

The little filly snickered behind a hoof. "Tats a siwwy name. Hewwo Twixie, I Midnight.”

Trixie placed a block on top of the others and asked. “So, Midnight, ya didn’t get tuwned to a foaw by yasewf wight?”

“Of couwse not! I can’t say what happened, but I basicwwy been punished fow messing with ya ponies.” Midnight explained.

Trixie smirked upon learning of that fact. Maybe that meant there was a way to get her to spill the beans on Twilight and her friends. She looked over next to her, ensuring that the “spy” teddy was nearby while she kept stacking blocks and talking to Midnight. If she could befriend this foal, maybe she could get the information she needed.

Just maybe...

After what felt like two hours’ worth of chasing the foals around, Rainbow Dash was quite exhausted. She was panting heavily after the rather intense game of hide and seek, as she was chasing the changelings who were flying around all over the library as baby copies of herself. “Get back here!” She roared, snatching Ocellus from the air before she saw Thorax zooming by. “Can you foals just stand still?! I already found you!”

“Yeah, but now ya gotta catch us!” Thorax nagged at Rainbow while Ocellus was blushing as she followed her brother.

However, Rainbow eventually caught up with the changelings. She captured the two just before she crashed into the bookshelves. Shel landed on the ground with the two babies laughing and giggling, bouncing up and down on the daredevil’s belly. “Alright, I caught you two!” The speedster wheezed, feeling exhausted.

Thorax nuzzled her and babbled. “Tat was fun. Can we pway again?”

“Yeah, pwease?” Ocellus whimpered as she placed her hooves over her face.

Rainbow was too tired to respond right away as she plopped the two changelings in the playpen. “Maybe later. For now, I need to find the other foals.” The pegasus then heard the sound of the two colts giggling and enjoying themselves.

She flew upstairs only to look in horror to see the two colts were throwing diapers all over the place in Twilight's room. The entire room was covered in padding. “What are you colts doing?!” Rainbow Dash roared in frustration.

“We just pwaying!” Blueblood squealed at her as he threw several diapers into the air.

Hoity Toity threw his hooves across his chest and pouted. “Yeah, we make better diapees tan these with our mommy.”

“It doesn’t matter! This is insane! You two pick up these diapers this instant!” Rainbow scolded them. “I’m in no mood for games anymore.”

“Ok.” The two colts reluctantly grumbled as they nevertheless began to scoop up the padding and throw the diapers into the closet.

Rainbow then turned to see Zecora’ on Twilight’s desk, mixing potions and laughing hysterically. “Zecora, stop! Those aren’t toys!” She shouted as she flew across the room to try to stop the baby zebra, but it was too late!

Zecora was pouring a strange mixture. Suddenly, her flask lit up, and a side of the library exploded, covering the entire room in a foamy substance!

Rainbow squeaked as the foam rushed her and the other foals caught into it downstairs. Soon the entire library was covered in the white substance, with the rest of the foals caught in the tide. They all started to splash into the foam as well, throwing foam at each other. And Rainbow was lying in the foam with most of her body covered in it. She just stared up at the ceiling, looking somewhat dazed.

The rest of the foals didn’t care; they just went about playing in the foam, Thorax and Ocellus splashing and throwing the foam at each other.

Zecora took a hoof of the stuff and shoved it into her mouth. “Oh yum!” She exclaimed! “It tastes wike formula!”

Discord took handfuls of the stuff and shoved it into his mouth, squealing in delight as he declared! “Oh, my Cewestia! It does taste wike fowmula! So good! Ya outdid ya self, Zecowa!”
The baby lord of chaos waddled off, rolling the foam up into balls and tossing them at the other foals.

The other foals got mad at him first, but they soon started to roll the balls of foam and toss them back at Discord. A “snowball” fight soon started with the balls of foam being tossed all over.

Seeing the chaos unfold, Discord sat down with a bag of popcorn, clapping his claws and enjoying the madness as he began to shove popcorn into his mouth.

The only two not going nuts were Midnight and Trixie, who both swam up through the foam and popped their heads up.

Trixie looked over. Seeing that Rainbow Dash was indisposed, she took the opportunity to question the alicorn. “So...um, Midnight? Ya was the fiwst to twy wegwessing evewypony?”

“Yeah, bu it didn’t wowk out too, weww.” Midnight irritably grumbled as she flew up out of the foam.

“Yeah, but Stawwight is gonna wescue me and tuwn me back into an aduwt.” Trixie whispered under her breath.

Midnight’s eyes lit up and whispered. “Ya serious?... She is stiww out thewe, wegressing ponies wike I taught her?”

“Yeah. I dun know wha her pwans awe. Aww, Trixie cawes bout is getting wevenge on Twiwight and hew fwiends.” Trixie replied with a smirk, seeing that Midnight was now interested.

The alicorn princess tapped a hoof to her chin. “Wha's da catch?”

A grin grew on Trixie’s face. Midnight had taken the bait, and now it was a matter of reeling her in. “I need more info on Twilight and the others fow hew. I tink she gonna try regressing them., I got some good info bout ta Apples. Tey has a bat problem. I heard of the fruit bats sucking the juice fwom ta apples….” Trixie paused as she took the time to suckle on her hoof with some tasty milk foam, then she added. “Wha if we get hew to twy stopping them alone.”

“Right! Bats attract bat ponies! Maybe they should turn her into a baby bat pony? Tey scoops her up, and then she has to be raised as a bat pony, brilliant idea!” Midnight cheered.

Trixie was starting to get excited. “Yeah, weww...wha about ta west?”

Midnight irritably grumbled again as she tapped a hoof to her chin. “Not sure, I mostwy have been under ta watch of Fluttershy…but I know tat Twilight has hew friendship lessons! Tey got a lot of info on tose ponies!”

Trixie's eyes glowed: This was exactly what she wanted...revenge! Now she was going to have it, thanks to this evil baby alicorn. The unicorn filly then asked. “Ok, but wha about Wawity? She’s not gonna be easy to get along with.”

Midnight just yawned. “Pwease, just have her be tempted with some fancy jewel or something and have it be in Manehattan or Cantewwot. If she gets picked up by some posh ponies, she’ll live a wife of luxury as a foaw. That mare won’t be able to wesist such a pampewed wifestywe.”

“Ok, what about Pinkie Pie and Twilight? Those two were turned to foals before, and on top of that, they both seem to be rather hard to trick.” Trixie commented with concern.

Midnight replied. “Eh, if we can get one, tey can’t use ta Elements of Hawmony, and we win. Besides, it’ll be hilarious if they do find their friends onwy for them to have to cawe fow them as babies! We need to find those lessons and exploit ta info.”

Trixie smiled. “Tanks fow helping me ensure I can town back into a big pony,” And then she asked. “Wanna make Wainbow’s wife miserable?”

“Oh yes!” Midnight exclaimed with a devilish grin!

“Hey, did I hear ya two want to make Rainbow Dash’s wife miserable!?” Discord shouted, waddling over in his crinkly pampers.

Midnight snickered. “Yes, and I tink ya can have a wot of fun with ya chaos magic! Hewe’s ta pwan.” She then got Trixie and Discord to huddle together as they discussed a plan to make Rainbow Dash’s life more miserable.

Discord cracked his knuckles as he got up. “Oh, this is gonna be fun!” He then scrunched up his face, and tendrils of magic swarmed around his tiny body. He summoned as much chaos magic as his little body could as he sent it outwards! He turned the foam thicker, making it bright blue and pink. Then it spread out, covering the entire treehouse.

Rainbow Dash just watched in horror as the tendrils of pink and blue foam covered everything in sight. “No! No! No! Discord, stop!”

But it was far too late with Rainbow Dash’s hooves no longer on the hardwood floors but instead a soft, rubbery substance. She shuffled across the bouncy floor, trying to grab the little troublemaker, who ran off giggling and clapping his paws in glee.

Midnight clapped her hooves together, enjoying the madness. “Tis is so awesome! I haven’t had tis much fun in ages!” She then came over to Trixie and held out a hoof. “Now, while Wainbow Dash is distwacted, why dun we do some hunting fow info?”

“Good idea,” Trixie replied, and the two went upstairs to find the friendship lessons that Twilight kept.

The two foals began looking through the basket full of scrolls, opening them and pouring over them. Midnight grumbled as she found one about Rainbow Dash and her having an opening to the Wonderbolts academy. “Aha! Found sometin’ useful!”

Trixie waddled over. Despite her reading level being diminished because of her regression, she could still make out some words. Just thinking about humiliating Rainbow in front of her idols put an evil smile on the filly’s face. “Yes, tat’s gweat! Even if she tuwns back to nowmaw somehow, she’ll be a laughing stock fow ta west of hew wife!”

Midnight smirked as she then picked up the lesson about the Flim Flam brothers making a machine that produced apple cider and squealed. “Hey, check tis out!”

Trixie read the lesson through and was a bit confused. “So wha? Who awe tese Fwim Fwam bros? Tey sound coow, but how does tis hewp?”

Midnight started to bounce up and down on her padded rump as she explained. “I heawd tat tey awe makin’ a potion to make ponies younger. Is probably fake, but Stawwight can probably help tem make a weaw age regression potion!”

Trixie snickered behind a hoof, thinking how horrible it would be for the Apples to have to see Flim and Flam destroy their family farm. “Tats a gweat pwan too! No matter what happens, we will make tem suffer!”

The fillies started to chuckle evilly, but then Midnight suddenly slammed a pacifier into Trixie’s mouth. “Shhhh! Wait!” They then heard Rainbow Dash coming upstairs. Midnight quickly took a jar of ink and spilled it all over her and Trixie’s hooves as she shouted! “Stawt smearing tings with ya hooves, act wike a siwwy foaw!”

Trixie did as Midnight instructed, getting her hooves filled with the ink and smearing it around, and splattering it all over some blank scrolls.

“What are you foals doing up here?!” Rainbow called and then gasped, seeing the friendship lessons scattered all over the floor. “No!!!!” She quickly snatched up the foals and looked over the scrolls! She sighed relief upon seeing they mainly were okay with only a few splotches of ink on them.

But Rainbow had had enough as she picked up the foals and shouted at them! “What were you two doing up here?! Why were you messing with Twilight’s stuff?!”

Trixie quickly came up with a lie, whimpering as she said. “We just wanna pway and make a pictua...we sowie….”

Midnight gave Trixie a wink, approving of the simple lie as the daredevil mare just gave an exasperated sigh. “Fine, but don’t do this again, alright?! Now come on. Let’s get you foals fed; then it’s off to bed. I’ve had enough of this craziness for one day!”

The foals smirked at each other, seeing that Rainbow Dash was oblivious to their true intentions as she placed them on her back, and they flew downstairs.

Trixie herself was feeling rather triumphant; She now had some secrets to give to Starlight.

Later that evening, Twilight and her friends returned to the Golden Oak Library from their long trip to Canterlot. Twilight herself was somewhat nervous about the state of her library and of leaving Rainbow with eight foals all by herself.

Twilight slowly trotted up to the front door and sighed relief upon seeing things looked relatively normal from the outside.

However, Pinkie sniffed the air. “Why does it smell like formula?”

Applejack sniffed the air too, and if by instinct, one word came to mind. “Zecora.”

Twilight gasped! She was well aware of Zecora’s obsession with making “potions,” most from what she heard were somewhat volatile! She burst open the doors of the library, and her mouth dropped open at what she saw! The entire library was covered in blue and pink style foam padding, looking like the innards of a bouncy castle.

The rest of Twilight’s friends eventually caught up with her, looking around the place with utter bewilderment! Pinkie, however, just burst into laughter and then shouted. “This is awesome! It’s a bouncy library now!” She squealed and started bouncing around like a rubber ball while the rest of the mares ran upstairs, all now fearing a little how the foals were doing. But when they reached the top, all gave sighs of relief, seeing that all the foals were sleeping soundly.

Rainbow Dash looked over with bloodshot eyes, her mane was a mess, and her coat was covered in green foal food, formula stains, and ink splotches. The daredevil looked somewhat nervous as she stammered out an apology. “S-sorry about the library. This all happened when Zecora made a bunch of foam explode, which I think was baby formula. Then Discord used his chaos magic to turn your library into a nursery, sort of,” She took a moment to catch her breath before finishing. “But I did change all their diapers, fed them mashed peas, and put them all to sleep. And I made sure to feed them bottles of formula if they woke up.”

Twilight looked over the foals, all sleeping peacefully around the room, with Trixie and Midnight sharing a crib while the rest of the foals were sleeping sporadically on the floor on little mats, with blankets covering them. Despite the state of the library, Rainbow Dash had done an admittedly decent job keeping the foals in check.

Rarity scooped up her sleeping colts and asked. “I hope my foals were well behaved?”

“Yeah, they were mostly fine...minus throwing diapers everywhere.” Rainbow bitterly muttered.

“Oh my! I’ll scold them about such unruly behavior.” The fashionista insisted.

This made the other ponies snicker as Fluttershy picked up Midnight and Discord and started to strap them into her stroller as she replied. “I’ll make sure Discord is grounded for this and fixes up the library when he wakes up.”

“Alright, but don’t be too harsh. This fabric probably saved the foals from getting bumps and scrapes.” Rainbow insisted, remembering having a few close calls, especially with the changelings wanting to fly all over.

Twilight nodded in approval as she took another look around. The foam material (despite its babyish look) was rather prudent regarding future age regressions. “Yeah...actually...this might sound weird, but maybe keeping my library ‘foal proof’ for now wouldn’t be too bad of an idea. I think I'll keep my place like this until we know for sure that the age regressions have stopped.”

“Yes...I agree this material does make things safer for foals,” Fluttershy agreed, but she still gave a glare at Discord. “But still, Discord will be grounded for this. He can’t just use his chaos magic without approval or permission.”

Rainbow Dash rolled her eyes, not agreeing with her friend in the slightest. “Ugh, when did you become such a mom, Fluttershy?”

“Well, unlike you, Rainbow, I need to make sure Discord is behaving,” Fluttershy commented rather sternly, trotting off with her foal before Rainbow Dash could retort.

Pinkie eventually came bouncing back upstairs as she scooped up the changelings. “Aww, they look so peaceful and happy. Thank you, Rainbow! I think you did a great job! Next time though, I suggest maybe throwing flour over yourself to calm them down.” She hugged her friend before bouncing off.

Rainbow blinked, looking confused. “Flour? What is she talking about?”

Applejack then came over and picked up Zecora and grumbled. “Don’t you worry, Rainbow? I’ll scold Zecora myself.”

“Again, don’t worry about it; Twilight said, this is fine. I don’t get why you and Fluttershy are so mommy-like.” Rainbow grumbled as the farm mare shook her head.

“You’ll get it when ya have foals of your own, sugarcube.” Applejack replied before she walked off with Zecora sleeping on her back.

Seeing that only Twilight was left, Rainbow Dash turned to see her friend was looking over Trixie sleeping soundly in her crib. Twilight had this peaceful smile over her face as she whispered, “She wasn’t a little troublemaker by any chance? Was she?”

Rainbow Dash winced and rubbed a hoof over her mane. There was one thing she left out. “About that...she and Midnight got into a pot of ink and spilled it on some of the friendship lessons you had stored away.”

Twilight gasped in horror and shouted! “Oh no! They didn’t ruin them, did they?!”

“Of course not! They just got the ink smeared on some unused scrolls!” Rainbow Dash explained, frantically trying to clarify.

Twilight ran over, checking the box where the scrolls were kept. She made sure they were fine before she sighed in relief. “Alright, good, I hope this is a lesson that you shouldn’t bite off more than you can chew. This could’ve all been avoided if we just got another pony or two to help you care for the foals.”

“Yeah...trust me, I’m NEVER! Going to do something like this again! I’ll write about it, and you can send it to Princess Celestia tomorrow if you’d like,” Rainbow replied before yawning; the pegasus mare was quite exhausted as she added. “Now, I’m gonna go hit the hay; see ya later.” She then flew off out the window, feeling rather beat and at the same feeling relieved she didn’t have any foals of her own to take care of.

Trixie woke up in her crib the following day to feel her rump being cleaned as she was going through another diaper change by Twilight. She didn’t bother protesting or anything, instead of letting the mare do her job. She was somewhat surprised to see that the room still looked like a nursery with padded pink and blue walls. Twilight must’ve noticed Trixie was awake now as she asked. “Good morning, little one. How did you sleep?”

“Trixie swept fine, tanks,” Trixie yawned as she stretched her tiny limbs. She was still rather tired but was feeling relaxed, confident she would be a big pony again. However, there was still that burning question in her mind. So Trixie gave Twilight her best pair of puppy dog eyes and asked innocently. “Um, so wha did Pwincess Wuna wanna tew ya yestewday?”

Twilight looked down at her charge with a smirk. “Sorry, but it’s a secret. As adorable as you are, I can't trust you with that information yet. Besides, you should be glad I'm not punishing you for digging through my friendship lessons yesterday while I was gone.”

As Twilight started to tape Trixie up in a fresh diaper, the little filly replied. “Twixie didn’t do anythin’. Twixie was just pwaying with ta ink, and we happened ta need a scroll.”

Twilight finished making sure the tapes on Trixie’s new diaper were secure before continuing, “Well, in any case, that was still rather rude. However, I'm willing to forgive you on one condition.”

“What’s tat?” Trixie asked in a suspicious tone.

As she explained, the unicorn then showed Trixie a colossal package of Luna brand, extra-thick, super-absorbent diapers. “Princess Luna got me these brand new diapers! Also, while on the train, my friends and I decided you're going to hold a show tomorrow wearing these along with an adorable outfit that Princess Luna and Rarity made for you!”

“Wha?!” Trixie wailed. She kicked and whined at seeing how thick the diapers were in the package, looking like they had triple the padding than the ones she went to sleep in. “Bu..bu...bu….” She could only stammer out, seeing that she was about to look incredibly humiliating probably.

“No buts! We’ll get you practicing your routine today! Then tomorrow, we're going to have you perform at Cheerilee’s schoolhouse, where we’ll set it up for the rest of the foals.” Twilight squealed, clapping her hooves and looking rather excited.

“Ya gots to be kidding me!” Trixie groaned as she was tucked back under the covers in her crib. Not only had she learned that Twilight still had a secret, but now Trixie had to give a stupid performance. This was not good! What's worse, she only had a few days left; she needed to learn what that secret meeting was about and fast!
