Prologue: The Bite that started it all...

Dusk was slowly falling over Sweet Apple Acres as Fluttershy flew over a sea of apple trees. The pegasus, however, was rather disgruntled as she was there at Applejack's request, trying to help the farmer get rid of some vampire fruit bats. The pegasus was instead against how Applejack was treating the other bats seeing that they were probably just migrating. But she promised the farm mare she would help, but she would do this her way.

The pegasus was unsure of how to deal with them, seeing as she'd never talked to them before, and she didn't want to use her stare. But she felt she had no other choice when all her friends were telling her to do so. This wasn't something she wanted to do, but Applejack was her friend, and she wanted to help, and it seemed that there was nothing else she could do to help.

But as Fluttershy looked around the orchard, there didn't seem to be any fruit bats. She scratched her head, wondering where they could be, and looked around the orchard in the hopes that the fruit bats had flown off by themselves.

"Oh, thank Celestia, they moved on." Fluttershy whimpered with a smile as it seemed she wasn't needed anymore and wouldn't need to use her stare. She was about to leave when she felt a prick in the back of her neck as if something just bit her! She looked around and thought she saw something flutter through the air. The pegasus looked around the orchard, trying to figure out what bit her? Then she felt her body change as she groaned, holding a hoof to her belly. She doubled over and started to look at her yellow coat, which was beginning to look rather shaggy, her pink mane and tail looking like a frazzled mess. She then felt her teeth and mouth ache and put a hoof inside, feeling her normal molars had turned into sharp fangs.

Then her ears started to hurt, and while Fluttershy couldn't see, she could feel that they were much pointer, and not only that, Fluttershy could hear all kinds of noises she's never heard before. The pegasus was swishing her head about as if it was on a swivel, hearing bugs whiz by and the whistle of the wind go through tree leaves. But then things started to get weirder as she looked up to see that the trees began to grow taller, and the apples surrounding her seemed to look a lot bigger. It didn't take her long to realize she was shrinking in size!

Fluttershy started to get worried as she tried to crawl towards Applejack's home, hoping to get to her and have Twilight fix whatever was happening. But it got harder to move as her limbs were much stubbier and pudgy.

Fluttershy eventually plopped down onto the ground on her rump and couldn't see what she looked like. But the pegasus knew that she had turned into a baby. All of this started to make her feel antsy as her eyes began to water. Then her nose started to sniff, and the fruity aroma from the apples on the ground got her attention.

The little filly slowly got up on her pudgy limbs and waddled over to one of the apples, taking one and plunging her tiny fangs into the flesh of the fruit. She then began to suck the apple juice, which was odd. She'd eaten apples before, and it's not like she was a mega fan of the fruit like her friend Applejack. But for some reason, she couldn't stop sucking out as much juice as possible from the fruit, being almost addicted to the flavor. The little bat continued to suckle away with a little smile, which kept her mind busy from the fact she was regressed into a baby. Then she turned to see something else on the ground, a plush toy. She slowly picked it up, knowing it was as big as her.

The plush was that of a bat pony with a little button on the belly. She clicked it, and a sharp ringing came out from the toy. Fluttershy blinked, being somewhat confused as to what this toy was. The baby bat pony shrugged, hugging it close to her chest, finding it comforting to hold it close.

The foal could feel herself getting tired, with her eyelids drooping. The little filly went on her back, wrapping her fluffy pink tail around her as she latched onto another apple and started to suckle the juice from it once more.

A few hours went by, and another bat pony flew through the night, looking down towards the ground of Sweet Apple Acres. The bat pony was gorgeous, her coat was a light yellowish hue, and her mane was a bright orange-colored mane. Her eyes were a reddish-orange which contrasted with her two dark blue leathery bat wings. She was busy looking for something.

"Another day, another bit." The bat mare (named Mango) mumbled as she was somewhat exhausted, having just gotten off a twelve-hour shift as a royal guard to Princess Luna. The only reason she hadn't gone to bed yet was that the other night her foal (Echo) had dropped her toy somewhere near an apple orchard they'd visited. Her toddler had kept whining about it and having tantrums nonstop since (on top of a few soaked sheets that had to be dealt with).

Lucky for Mango, her husband took care of their little one, allowing her to look for the toy. "Hopefully, this won't take too long," Mango mumbled. Luckily, the toy released a high-pitched ring that only other bat ponies would hear. So if it were to go off, it would make the search much easier. As the bat mare approached the apple orchard, her nose was hit by the sweet aroma of the hundreds if not thousands of apples below. Both she and her daughter preferred mangoes (in fact, they both were addicted to them). Still, Mango had to admit it took a lot of self-control, not just to swoop down and start going to town on the entire orchard.

But Mango shook her head, trying to regain her self-control and not get caught up in her fantasies. That was when she heard a loud ringing noise, and Mango instantly recognized it as her foal's toy! To her surprise, the bat pony flew through the orchard at high speed to find a bit yellow-coated bat pony lying on the ground. Said bat pony was sucking away on an apple with the plush toy held in the pit of her tiny forelegs. Seeing the filly suckling on her apple, with juice dribbling down her chin, was rather adorable. But Mango also noticed that the ground was soaked where the foal laid. "Uh oh, somepony made a mess." The bat pony snickered as her cheeks flushed red seeing the little one peed and had no protection for accidents.

Mango then looked around the orchard, wondering if another mother or father had left their baby there. Her senses were on full alert, her ears twitching and her nose sniffing the air. She smelt the scent of other normal ponies: Unicorn, pegasus, an earth pony, but no bat ponies. "That is so odd?" Mango mumbled as she scratched her head, wondering how this baby bat pony got here? Maybe the little one got lost and had wandered into the apple orchard on her own?"

"Hello!? Anypony here?!" The bat mare shouted, and her voice carried through the trees, but it was met with silence. It seemed that there wasn't another bat pony in sight. She gave a loud groan slamming a hoof to her face feeling rather bad. She didn't want to just "take" a baby. But she couldn't leave a bat pony to stay here; most normal ponies wouldn't know how to care for a baby bat pony. Heck, most ponies don't even know bat ponies exist.

"Looks like I have no other choice." Mango sighed, seeing that she had to take the baby and care for it. The mare picked up the little baby and taped her up in a fresh diaper (despite her foal Echo being potty trained, she kept a few in a diaper bag just in case). The diaper was cute, with little baby blue bat prints on the padded fabric. She then plopped the foal onto her back.

Mango then stuck the toy in her bag along with a few apples. She then threw out her leathery bat wings and flew off as the sun started to rise. Mango was exhausted and planned to go to sleep when she got home. But when she got up, she'd first try to find this little one's parents.

Chapter one: Meeting the Bat Family

“Hey! Sissy….hey!” Fluttershy groaned as she slowly got up and rubbed her eyes as she tried to figure what had happened to her and what's going on. She then saw a young, gray coated bat filly who was standing up, with her hooves against the bars of a crib. The filly looked around as she was starting to see that she was in some sort of nursery. There was a diaper changing table, some blocks and plush toys strewn about, and a bed with rails set across from the crib. It seemed that the room was the bat filly’s and her family had set up the crib for her. She maneuvered herself onto her hooves and squeaked, feeling the warm, damp diaper between her chubby thighs.

“Oh dear, you had an accident!” The bat filly chirped as she fluttered over and lifted the baby out from the crib. Fluttershy wiggled about in her squishy padding as she was taken over to the changing table.

The filly then went about changing Fluttershy’s diaper, going over it rather clumsily as Fluttershy could tell that the young bat pony had never changed a diaper before. But she seemed to know what she was doing as she finished strapping the baby pony up in a fresh diaper then chirped.“There ya go!” She then plopped Fluttershy down and said. “Hello. My name is Echo, what’s your name?”

“My…my name is Fluttershy.” The little filly replied with a squeak, unsure if Echo could understand her.

“Uh oh, looks like you can’t talk yet,” The bat filly giggled, seeming to only hear baby babbles. “Well, that’s otay. Ya dun need ta talk!” She then trotted over and said. “Come on, I wanna show ya stuff!” She then took Fluttershy by the hoof and led her through the house.

Fluttershy blushed, feeling her legs waddle in the diaper. It was awkward at first but she got used to it, being able to waddle alongside Echo (and feeling oddly proud about it). They first came to the parents' bedroom, where Fluttershy peeked inside to see the two sleeping together with the mare, Mango, and her husband.

“There Mommy and Daddy are asleep, but they’ll be up later, dun wanna wake tem up.” Echo whispered.

Fluttershy nodded, her cheeks flushing pink upon realizing that Echo didn't tell her their names.

Echo then rushed off down the hall to a bathroom where a training potty was set up. “Tis is ta bathroom. Ya can’t use it because ya baby, but I can teach ya how to go later!”

Fluttershy blushed again at the thought of having to relearn potty training. Hopefully, if she could find Twilight, that wouldn't be the case.

The two then came into the kitchen where they came upon a bowl of mangoes. Echo wiggled about, launched herself into the air and landed next to the mangoes. She took two and flew back down as she exclaimed! “See, this is my favorite food! Mama keeps them up high so I can’t get them, but I learned ta fly!”

Fluttershy' eyes were glued to the mangoes as drool came down her chin. They looked so juicy and ripe, and they smelt so good! The little filly waddled over to one of the mangoes as she lifted it up to her face, then dug her tiny teeth into the flesh of the fruit. She then began to suck the juice out with a smile on her face. The two fillies began to suck the juice from their fruits until they were shrunken husks. The baby bat ponies were so invested in their meal that they didn't notice Mango walking into the kitchen.

“Well, there’s my little troublemakers!”

They both squeaked as they turned to see Mango standing over them with an angry glare. She took her daughter and scolded her. “How many times do I have to tell you: Don't take mangos without Mommy or Daddy's permission.”

“But mom!” Echo whimpered. “Baby sissy was hungry, and I was just trying to feed her!”

Mango then turned her attention to Fluttershy and plopped her into a highchair as she took out a bottle, plopping it into the foal’s mouth. “She shouldn’t be sucking juice out of fruit yet, she might break her teeth, sweetie.”

The baby bat pony took a hold of the bottle and suckled, surprised to taste an abundance of fruit from the drink tasting mango, pineapple, apple, and an assortment of berries.

“No fair, she getting ya milkshake!” Echo complained.

Fluttershy squeaked in surprise upon learning that she was sucking on a bat pony mare’s milk! No wonder it was so tasty.

Mango turned to her daughter, giving her a sippy cup filled with milk. “Well, you need to be weaned off mama’s milk. But you can still have some if you behave.”

Echo squealed in delight as she began to suckle on the contents, and drained the sippy cup rather quickly.

Meanwhile Mango maneuvered over to Fluttershy and gave her diaper a few pats, surprised it was clean. “Sweetie, did you change the baby’s diaper?”

“Yes, Mama, she was wet!” Echo replied.

Mango smiled as she ruffled her daughter's mane. “Well, thank you! You’re so kind and helpful,” She then ruffled her daughter’s mane as she yawned, flapping her wings. “It’s still so early.”

“Yes, and it’s great to see the baby sleeping well,” The husband yawned as he came into the kitchen. The stallion himself looked much more like Echo with a dark grey coat, piercing gold eyes, along with a cropped dark blue mane and tail. The stallion was well built reminding Fluttershy of Soarin from the Wonderbolts. He trotted over to the baby and pointed to himself. “Hello, my name is Sonic. You probably met my wife Mango, and my daughter Echo."

Fluttershy threw her hooves over her eyes as she was rather surprised by his bluntness.

“Oh stop, you're scaring her.” Mango snickered as he came over and kissed her husband on the cheek. He nuzzled her and they went off to make breakfast, making a fruit salad for him and his wife.

The two then went and talked about things with Mango starting. “I still have another shift tonight. Would you mind looking after the foals again?”

Sonic looked up with a sheepish look. “I would love to, but the Shadowbolts are having a practice and they’re probably already angry with me. I missed practice yesternight, I don’t want to keep leaving my team hanging.”

“Oh, I'm sorry, honey. I completely forgot your big show is coming up!” Mango cried.

Sonic turned towards Fluttershy, gave the foal a sympathetic smile and sighed. “It’s fine, the Shadowbolts will understand, seeing that we have a lost baby on our hooves.”

Echo rolled her eyes and then shouted. “Mom! Can’t the baby come with me to Nightcare?”

The couple looked at each other with rather surprised looks as Sonic said. “That’s… actually not a bad idea. Why don’t we have her go to Nightcare? I'm sure we can have the staff help us locate her parents.”

Mango gave a nod of approval with a smile. “That sounds like a great idea! I’m sure by tomorrow morning somepony will pick this baby up.”

As everypony was talking, Fluttershy sat just back in her highchair, sucking on her bottle. It was so odd getting a baby’s perspective of life.

Mango then went and took Fluttershy out of the highchair, placing her into a stroller as she said. “Well, at the very least we should have them go to Nightcare together while we go out and see if we can get information.”

The little baby batpony started to get, excited seeing she was about to be put in batpony version of "daycare" and see what’s that like.

“Alright, well I better get going. Don't want to be late!” Sonic chirped as he kissed his wife on the cheeks as he nuzzled his daughter. He then went down to Fluttershy and blew a raspberry into her belly, making the filly give adorable squeaking noises as she kicked about in her diaper.

“Awww, such a cutie, I hope when we find your parents and we learn what your name is” Sonic commented as he ruffled her mane before flying off.

“Yeah! And ten we can be friends right?” Echo shouted as she was bouncing around.

“Yes, it sounds like a plan. Now come on you two, let’s get going,” Mango yawned as she picked up Fluttershy and took her daughter by the wing as they headed out the door.

The trip to “Nightcare” was one that Fluttershy would never forget as she looked around, seeing that they were deep within a cave, with the sound of water rushing around her and the gentle drip of droplets coming down from the ceiling. The batponies lived within homes made of stone and they flew about doing things most other ponies would do from shopping at fruit stands, milling about and talking, and even foals playing in the street.

Fluttershy noticed there were long poles where bat ponies would wrap their tails on the horizontal ends and talk to each other upside down (while some were just napping with their wings wrapped around their bodies). It was a lot to see and take in, and she hoped that if she turned back to an adult she could visit and learn more about them.

Of course, Fluttershy and Mango also got a ton of unwanted attention from other bat ponies who flew over to “daww” at her and ask Mango about her. The older mare of course did her best to explain that Fluttershy wasn’t hers and she was looking for her parents. They eventually made it to the “Nightcare”, which was a small building carved into the side of a cave. As they entered it, it looked much like a typical daycare would in Ponyville, with a barrier and the front desk keeping the little ones in a giant play area, while caretakers were going about caring for the babies and toddlers.

As they came to the front desk, a nanny looking bat pony looked down with a smile and cooed, “Aww, Mango, you didn’t tell me you had another baby!”

“She isn’t my daughter,” Mango explained with an exasperated sigh (as she had said this a few times already). “You can actually help me, because I'm trying to find out who this little one belongs too.”

“Oh really, so she’s lost?!” The nanny asked.

“Yes, we found her in an apple orchard near Ponyville yesternight.” Mango explained.

“I’ll be on the lookout and ask every pony that comes by if they know anything.” The nanny replied as she took the two over to the other side of the gate.

Fluttershy was plopped down on her padded rump, looking over a bunch of other foals all roaming about, some munching on cut up pieces of fruit, others chasing each other about in the air or hanging from the ceiling with their tails. It was all rather adorable and she couldn’t help but feel giddy being surrounded by so many adorable baby batponies.

Echo was getting rather excited too as she took Fluttershy by the hoof. “Come on! I'm gonna teach ya all kinds of stuff, gonna teach ya how to fly, hang from ya tail, steal mangoes…mostly on how ta steal mangoes…”

Fluttershy couldn’t help but snicker at seeing how addicted to mangoes the toddler was, and she was also feeling rather excited for all the things Echo was going to teach her, seemingly forgetting that she should be figuring out a way to get back to Ponyville.

Chapter Two: Fluttershy's Night Out

Fluttershy enjoyed herself with the other foals as she played with Echo, stacking blocks and playing tag with the other baby bat ponies. It wasn't long after they had their lunch (Echo and the older bat ponies had mashed fruit); meanwhile, the little yellow-coated bat pony was stuck drinking a bottle of "fruit milk" that was probably supplied by their caretaker. Fluttershy didn't care as she'd grown quite accustomed to being a cute baby bat pony and loving the taste of the milk; it tasted about the same as Mango's milk, being just as tangy and delicious.

So far, the day was rather relaxing and enjoyable for Fluttershy, having not had to be angry about anything. She was then picked up by the caretaker as she was asked. "Do you know how to hang by your tail?" The former pegasus shook her head "no." The caretaker gave a sigh and said. "Well, guess we should set up a crib for you, sweetie."

"I can teach her!" Echo exclaimed as the little filly waddled over towards them.

"But sweetie, we don't want her to fall," The caretaker pointed out. "It takes practice to hang by your tail."

"Please!" Echo whined. "I taught a lot of ta foals here! My mommy says I'm really good at it."

Fluttershy did want to try hanging by her tail, just like the other foals. She waddled towards the older bat pony caretaker and gave her some cute puppy eyes. Despite Fluttershy not being able to communicate verbally, the older caretaker got the message and just gave a reluctant sigh. She then turned to look down at Echo. "Now Echo, you watch the little one. Come get me if anything happens."

"I will!" Echo exclaimed as the caretaker left to take care of the dozens of other baby bat ponies zooming about the room.

"Come on, I'll show ya how to attach your tail to the ceiling!" Echo cheered; she then took Fluttershy by the hoof, flew her up to the rafters, and assisted in wrapping the baby's pink, fluffy tail around the banister.

Fluttershy squeaked as she lowered her body towards the ground below; it was so strange being "upside down." Echo did the same and looked downward with a smile as she wrapped her body with her bat wings. The pegasus' cheeks flushed pink as she thought her diaper would slip off while hanging like this. But the diaper was designed for baby bat ponies with a diaper strapped around her crotch area, and she felt it was secure and snug.

The pegasus then buried her head into her chest and relaxed, seeming to feel like this was more natural than sleeping on her back. Echo then wrapped her wings around Fluttershy and kept her close as they nuzzled each other. Fluttershy had to admit Echo made such a great big sister. It wasn't long until the former pegasus was sound asleep in the embrace of the older bat pony filly.

Fluttershy was suddenly woken up by Echo as she nuzzled into her belly and shouted! "Come on! Gotta show ya where they keep ta mangoes! They are great!"

The baby bat pony yawned as she flexed her wings and flapped her tiny wings, going down to the ground below as she followed Echo. They then went to the pantry, where there were tons of fruits in a fridge: Bananas, oranges, mangoes, you name it. All of them were piled together in barrels.

Fluttershy's mouth drooled as her pupils went wide. The former pegasus then flew right towards the bunch of mangoes, followed by Echo as they sank their teeth into the fruit. They then sucked the juice from their fruit and drank to their delight.

The pegasus then wiped her mouth with a hoof and looked upward at a window nearby. Her foalish mind desired to see the outside world and explore the land of the bat ponies. She probably wouldn't get another opportunity like this.

Echo seemed to notice what Fluttershy was doing and asked. "Hey, wanna go outside and explore?"

Fluttershy gave a few excited nods as she bounced up and down in excitement Echo hugged her and then took the foal by the hoof. "Come on! We should go now before ta caretaker knows we left! Don't wanna get in trouble! Maybe I'll even help ya use the potty; Mommy and Daddy say I'm almost old enough to use the one they use. So if I can use it, ya can use it too, probably."

Fluttershy giggled a bit at Echo's enthusiasm; it reminded her of Rainbow Dash, even as a foal. Unsurprisingly, despite being younger than her, Rainbow had been potty trained before Fluttershy.

Echo then led Fluttershy out through the window, and together they flew towards the city ahead as Fluttershy became giddy with excitement. She knew what they were doing was naughty, but she didn't care. Maybe it was her foalish mind taking over her body. Regardless, she was excited to see the world of the bat ponies and what it looked like. Maybe she would tell Twilight about her findings when the alicorn returned Fluttershy to normal.

Mango was now dressed in her dark blue armor and flying through the castle halls doing her patrols, almost right into Princess Luna's chest.

Princess Luna looked down with a wide-eyed expression. "Oh my! Mango, how are you?"

The bat pony squeaked as she shouted. "Princess Luna, I'm so sorry! I didn't see you there, really."

"It's alright; I was lost in thought and wasn't paying attention to where I was going," The princess of the night apologized. She then looked downward again with an unsure look as she mumbled. "It's just; lately, I've been worrying about something."

"Worried? What do you mean?" Mango asked, being somewhat concerned about her good friend.

Princess Luna explained. "Well, recently, a very good pony named Fluttershy went missing. I've been searching for her throughout the dream realm and haven't found her, which I find most troubling. Her friends are worried sick about her. In fact, Fluttershy is one of the ponies who cured me of my dark side, Nightmare Moon. That I can't even find her through dreams is most troubling, I can visit the dreams of everypony."

"Oh my!" Mango gasped at the news! Then she paused, thinking it was odd that she'd found that baby bat pony the same night Fluttershy went missing. Maybe she was pulling at strings. "Well, I…I don't know if this helps, but I did find this strange baby bat pony recently."

"Really?" Princess Luna pondered. "I was not aware one had been born. Please tell me, what does the foal look like, and how old is she?"

Mango put a hoof to her chin. "Well, she has a yellow coat, a fluffy pink mane and tail, and fluffy yellow ears. She's quite young, no older than one, can't talk, and is diaper dependent, of course."

Princess Luna blinked as she asked. "Can you bring that foal here? She might just be the pony we were looking for. It sounds strange, but… well, have you heard about the foal pandemic?"

"Oh yes, we heard of the age regression pandemic happening in Equestria," Mango nodded in reply and then gasped! "Do you think Fluttershy was turned into a baby bat pony?!"

Princess Luna chuckled, seeing as she was too used to this. "Oh yes, I wouldn't be surprised, seeing that's become quite common as of late. Can you please bring this baby bat pony so I can see if it's Fluttershy?"

"Yes, princess! Right away!" Mango shouted, then flew off back to the nightcare. As the bat pony flew off into the night, she just hoped Echo and the new baby were still at nightcare and weren't getting into any trouble. Luna already knows how much trouble Echo was, and she was still only a toddler.

The two foals were currently going around the town with Fluttershy, admiring the bat ponies once more. She loved watching them sniff the fruit stands and with their pupils wide, being overly stimulated by all the fruits. The best part was they were admired by the other ponies, all dawwing at them and admiring how Echo was taking care of her "baby sister."

Fluttershy felt somewhat embarrassed being called that, especially since her diaper was soaked in urine from all the juice she was drinking. It had happened so fast she hadn't even had time to react, let alone try to tell Echo that she had to go potty.

The two were picked up by somepony as Fluttershy squeaked and squirmed about. She was laid down on a park bench and squeaked as her diaper was unstrapped and her rump was wiped. Fluttershy looked up to see that the pony changing her diaper was Echo's dad, who flashed her a smile and asked. "How did you two get out of nightcare?"

"We escaped, but the baby wanted to go out!" Echo cried as she was laid on another park bench as. Fluttershy felt a fresh diaper strapped between her thighs.

Sonic then put a diaper around his daughter as well, pouring some foal powder on her rump as he scolded. "Well, seeing you're out here and quite a long way from a potty, you need a diaper. Your mother would kill me if I let you go without one out here."

"Ugh, fine. I like diapers anyway! Tey comfy when I land on my bottom," Echo grumbled. "But I still the big sissy, right?"

Sonic ruffled her mane and nodded, then he put the two foals onto his back. "Well, we better get you two back to nightcare now."

"Ugh, can't we see you fly with the Shadowbolts, Dad? Please!?" Echo begged, shooting the best pair of puppy dog eyes she could manage.

Sonic scratched his mane. "Ok, I guess I don't see the problem. Your mother is going to give you quite a scolding anyways. I better just keep an eye on you two. Besides, at least the Shadowbolts' stadium has bathrooms, including changing stations."

"Yay!" Echo squealed as she clapped her hooves and followed her dad with Fluttershy bouncing along on the stallion's back, excited to see the Shadowbolts' show. She wondered if they would be just as good as The Wonderbolts from what little she remembered seeing them.

Meanwhile, by now, Mango had arrived at nightcare. Everything seemed normal, with parents coming and out picking up their kids.

But the caretaker started freaking out as she frantically exclaimed! "Oh, Mango, I'm glad you're here!"

"Yes, what is it?" Echo asked, being somewhat nervous about what the caretaker would say.

Sure enough, the older mare blurted out! "I'm sorry! Your foals escaped and ate all the mangoes! I...I would go after them, but I still have all these other little ones to look after."

"Echo!" Mango roared and hissed, being used to her rambunctious foal getting into trouble. She then pushed out the door and sniffed the air. She could easily smell her daughter's scent and began following It through the town of BatPonyville, bent on finding Echo and giving her quite a scolding! Not only did she raid the nightcare pantry, but she'd escaped into Batponyville all by herself! The last time Echo had done anything this adventurous, she had only just started potty training.

Fluttershy was sitting with Echo in the Shadowbolt stadium; it was surprisingly similar to the Wonderbolts' one back in Cloudsdale, except this one was built with shades of black, blue, and purple. There were still hoops and other stuff for the batponies to do all of their tricks. The little foal was snug with the older filly, ruffling her mane as they watched Sonic and the other Shadowbolts flying through the air and doing stunts. They were just as good as the Wonderbolts, if not better since they were doing this in an almost pitch-black cave with little light.

Fluttershy could hear the Shadowbolts using their voices as some sort of echo to locate things around them and avoid crashing into random objects.

Then, suddenly, Mango flew over and landed next to the foals. She put a hoof over her chest feeling somewhat relieved as she exclaimed. "Oh, I'm so glad you're both here, safe and sound!" She picked up Fluttershy, nuzzled her, and patted the filly's diaper as she sniffed. "Whoever changed, you did an excellent job at not going overboard on the powder," Then she turned to Echo and smirked. "I was going to punish you, but seeing you back in diapers is punishment enough."

"There's no potties here!" Echo whined with a cute pout on her face. "Daddy made me wear diapee!"

Mango was no longer angry but relieved the foals were ok as she sighed. "Well, it serves you right to leave Nightcare with your baby sister. But I'm just too happy you're ok. Good thing Sonic found you so quickly." She then sat down, putting the foals in her lap, and watched Sonic finish his practice.

Mango then talked things over with her husband as Fluttershy was amazed that Princess Luna knew she was missing and was looking for her. "So I'll take the foals to the palace in Canterlot to meet with the princess and turn Fluttershy back to normal," Mango explained.

"W…wow, that's crazy! I've heard of the age regression pandemic, but I thought it was all rumors!" Sonic exclaimed as he was rather shocked by the news. He then turned to Fluttershy and nuzzled her. "Well, I hope you turn back to a big pony soon. It must be quite embarrassing being in diapers again. Promise you'll put in a good word for us and make sure everypony knows we didn't turn you into a baby."

"Otay!" Fluttershy babbled and hugged him. This act got a series of dawws from the parents as the little baby bat pony nuzzled close to Sonic. She was a foal for only a day, but she couldn't help but feel sad that she was leaving already. Sonic and Mango were such great parents, and Echo was rather rambunctious. Still, she was kind and sweet in trying to make Fluttershy feel comfortable. For some reason, all this was making Fluttershy get worked up as the baby started crying.

"Hey, don't cry; you can visit us anytime when you're grown up, ok? Maybe you can help bridge the batponies with the other tribes." Sonic replied as he picked up the foal and snuggled her.

"Yeah, come and visit us when ya get back to normal!" Echo exclaimed. "Maybe by then, I will be fully potty trained!"

Fluttershy nodded and then snuggled into Mango as she took her and Echo both onto her back.

Mango then turned to her husband and kissed him on the cheek. "I'll bring Echo along, seeing as she probably wants to say goodbye to the baby, and you're still busy practicing."

"Alright, just be back soon," Sonic replied with a chuckle. He then waved a hoof at Fluttershy as Mango unfurled her wings and flew off into the night sky.

Chapter three: Baby Batponies Everywhere!

Mango spent several hours flying towards Canterlot Castle with Fluttershy and her daughter Echo sitting behind her. The bat pony mare was exhausted from flying dozens of miles to and from Canterlot.

They finally arrived at the castle with two little foals on Mango's back. They were both also looking somewhat exhausted (having skipped their naps and spent most of the evening running around). Mango eventually landed outside the castle; she laid her foals down, turned towards her daughter, and growled. "Now, Echo, you will be on your best behavior while you're here. Or you'll be grounded for a month."

"A month?!" The filly whined.

"Yes, that's right. I won't have any of your antics while we're meeting with Princess Luna, is that understood?" Mango sternly replied. "You stay with me and don't go wandering off on your own no matter what. If you need anything: A change, a snack, the potty, let me know."

"Otay, Mama." The little filly mumbled as she bent her head downward.

Mango then adjusted Fluttershy on her back as the three continued through the halls. They eventually made their way to Princess Luna's bedroom, where they found two batpony guards outside.

"Commander Mango, you're back already?!" One of the guards asked in surprise.

"Yes, I want this matter resolved by finding out who this little one is." The mare explained with an exhausted sigh as she was still recovering from all the flying she had done.

The two guards looked over at the little filly on her back and dawwed. "Aww, she's adorable!"

Fluttershy, feeling self-conscious, threw her wings over her eyes. But it only made the guards daww even more.

"Well, as much as I would love to coo over this cutie, we should make sure she isn't an adult who was regressed," Mango explained.

The guards nodded as they opened the doors. Mango went trotting inside to find Princess Luna standing by a mirror, seemingly getting ready to perform her duties for the evening.

Princess Luna turned toward them with a smile. "Oh, Mango, it's so good to see you!"

"Yes, princess. As requested, I came with the foal you suspect to be Fluttershy." Echo abruptly responded.

Luna then picked up the little baby bat pony in her magic and had her come close to her. She nuzzled the little one with her muzzle and cooed. "Oh, this is the little cutie you were talking about." She then looked at the foal rather thoroughly and gave her diaper a few loving pats. The princess of the night wasn't entirely sure if the foal was Mango's, seeing how shy she was, throwing her batwings over her eyes.

The princess of the night recognized Fluttershy almost immediately as she snickered. "Aww, she's so cute! Yes, I would say I'm ninety-nine percent sure that this is indeed Fluttershy." She then placed Fluttershy down and wrote a letter to Twilight about how her friend might have been turned into a baby bat pony. Her assistance was required in turning Fluttershy back into an adult pegasus.

Princess Luna then lit her horn and sent the letter to Spike as she turned her attention to Mango and asked, "When Twilight responds, she'll surely come by to turn the little one back to normal. In the meantime, would you like to stay at the palace for the day?"

"Yes, that would be great; my wings are killing me!" Mango replied with a sigh of relief.

Meanwhile, Luna started to play with Fluttershy a little bit, tickling her belly with a wing and making Fluttershy kick and coo. She reached out and began to suckle on one of Luna's hooves, making the princess and Mango daww.

Luna let Fluttershy suckle on her hoof for a bit and then hoofed her to Mango. That was when she noticed little teeth marks over her ankle.

"Oh dear, it looks like the little one bit you," Mango commented.

The princess of the night inspected her hoof and just gave a chuckle as she said. "It's fine; she didn't break the skin. As a snack, I had a few fruit tarts, so she was probably just sucking on some leftover tart jam on my hooves."

"Even so, I do apologize for that. I know I raised Echo to be better than that. I should've made sure Fluttershy knew not to do it either." Mango yawned. She then trotted off with the foals and was led by Princess Luna to a spare bedroom. The bat pony was rather impressed to see the room was rather big and even had a fully stocked changing table.

Princess Luna then smiled. "I hope this is all to your liking."

Mango bowed her head. "This is more than gracious, your majesty. Thank you for allowing me and my foals to stay here as a guest."

"It's no problem at all. Have a good day, and sleep well," Princess Luna yawned as she closed the door behind her.

As soon as the princess did so, little Echo turned to her mother and said. "See, Mama? I behaved! I not grounded, am I?"

"No, you're not, you were a very good filly, and now it's time for bed. So come on, let's get you to the potty, so you don't have an accident. Just be careful not to fall in again." Mango yawned once more, and she escorted her daughter to the bathroom.

"I not," Echo replied as she was brought before the toilet and pulled down her diaper.

A short time later, after getting her daughter ready for bed, Mango wrapped her tail around a banister. She held her foal within the folds of her wings as Echo clung to her. It wasn't long until they were comfortable and fell fast asleep.

Luna rubbed her hoof full of drool, chuckling as she thought about how Fluttershy was rather adorable as a baby bat pony, for however long she would stay that way. The princess of the night stretched her wings and then trotted over to the mirror as she was getting ready for her duties. But then she noticed that her body started to shrink in size, her growing hair outward, and her teeth became pointy. It wasn't long until she was reduced to a foal.

Having been regressed once before, Luna knew rather quickly she was a foal again. She quickly ran over to a mirror and gasped upon seeing her reflection! There, staring back at her, was an adorable little baby bat pony with two small and leathery bat wings where her once feathery wings had been. Her teeth were now tiny fangs. This wasn't just any old age regression; the princess of the night had turned into a bat pony as well!

Luna waddled to her door, hoping to find some pony to help her out. The little filly pounded her tiny hooves on the door while crying! "Somepony help! I got turned into a baby again!"

Eventually, the door opened, and two of her batpony guards entered. Looking around, one looked down at the little foal. Then he bent down and picked her up. "Oh my! Where are your parents, sweetie? Are you lost?"

But the other guard looked around the room, and that's when he realized that the baby was Princess Luna and started to freak out! "What the heck is going on here?! Where's the princess?!"

The soldier holding the foal looked closely at her and started to see that the colt resembled Princess Luna quite a bit. "I think Princess Luna has turned into a baby again!"

Princess Luna just pouted at the guards and snapped. "Seriously?! Can't ya understand me?! Just take me to my sister! She can get with Twilight and turn me back to normal!"

The guard holding Luna just gave her a confused look as he stammered, "I…I think she's trying to tell us something."

"Yeah, I thought regressed adults could still talk?" The other guard asked while scratching the back of his head with a hoof.

Luna got so frustrated as the guards seemed to have stopped listening to her, and she went and bit one of the guards with her teeth.

"Ouch! Hey, Princess Luna, don't do that!" The first guard exclaimed as Luna began to suckle on his hoof. The guard then slowly regressed into a foal as well, with his armor collapsing over him as his partner started to burst out laughing. His comrade pouted and snapped. "Whatcha laughing at?!"

The older soldier burst into even more laughter. "Aww, I can't hear you. Can you say Da-Da?"

The other foal got rather frustrated as he pounced on and bit the older pony. It wasn't long until the adult pony slowly regressed into a baby bat pony!

The two guards started fighting, flapping their wings and slapping each other. That is until Luna raised her wings and shouted. "Ya two, stop tis right now!"

"Yes, Princess Luna." The other two guards mumbled as they lowered their heads.

Luna gave an exasperated sigh before looking around the halls as she said. "Otay, let's go find my sister. She ta only one who can help us. But before we go, you must remember not to bite anypony."

"Ya bite us first!" One of the guards snapped back.

"Yeah!" The other guard shouted as well.

Luna just sat back with a cute pout. "Well, ya wasn't listening ta me! I can't stay a baby, I got my royal duties, and ya probably dun wana to stay as babies either. So we need to find my sister, or we'll stay like this."

"Yes, Princess Luna." The other foals chimed in.

"Otay wets go!" Luna replied and then had the other foals follow her down the hall, hoping they could find Celestia fast! Right now, the only pony that could turn them back to normal was Twilight, and she was all the way in Ponyville. So they'd have to contact Princess Celestia and have her send a message to Twilight.

The trio of foals eventually came to Princess Celestia's room and managed to open it. Then they came to Princess Celestia as she was going over some paperwork at her desk.

Celestia then turned to see her sister and the baby guards. She put a hoof over her mouth upon seeing how adorable they looked and gasped, not appearing to recognize them! "Oh my! Where did you cuties come from?!"

Luna tried to explain, babbling gibberish at her sister, but this made Princess Celestia daww as she levitated the babies into her lap and started to nuzzle them. Celestia then looked downward. "Oh my, you all need diapers! We don't need you leaving puddles all over the castle grounds. I don't know if any of you are potty trained," She then levitated three diapers over along with a container of foal powder and commented. "Lucky for you, I've been stocked with foal supplies just in case more ponies got regressed."

Luna got more frustrated, kicking and whining upon seeing her sister not listening to her. But Celestia quickly plopped a pacifier into Luna's mouth and chirped. "That's enough, sweetheart. We need to get your diaper on before you make a mess." The princess then laid the foals down on the ground. She then went about powdering their flanks and then strapping the foals up in fresh protection. Princess Celestia then made cute "baby talk" with the foals as she finished taping the diapers up, making sure they were snug.

But all of this "babying" made Luna and the other regressed ponies even fussier.

"Well, seeing as you're all bat ponies, I believe that you must be some lost foals belong to one of my sister's nightguards," Celestia I should investigate to see who your parents are…or if you're regressed, adults."

Luna groaned, rubbing down her face. Her sister was genuine, and she did appreciate her going out to help some lost baby bat ponies. But the truth was it would take forever for her sister to go talk to every bat pony guard under her employment. It could be a full day before they were back to normal, and Lina wanted to be out of diapers as soon as possible. Out of frustration, she shouted! "We dun have time for tis!"

As Celestia was going to leave her room, the princess of the night bit her sister on the hoof, and it wasn't long until the princess, too, was regressed in a cute baby bat pony. She had these pointy fluffy, white ears and cute little pointed teeth. The princess turned towards her sister and asked, "Did ya turn me into a baby bat pony?!"

Luna rolled her eyes and snapped. "Well, ya wasn't listening ta me! I had no other choice!"

"Well, I'm sowwie for that, but why did ya turn me into a baby again?!" Celestia shouted. She then looked over at the other foals and asked. "Also, who are all of you?"

The two colts went to attention, looking rather adorable with their padded flanks stuck out as they proclaimed together. "We royal nightguards!"

The filly pointed to herself and shouted. "I'm ya, sissy Luna! I've been trying to tell ya I was a baby, and we need help getting back ta normal! We dun wanna be in diapees!"

Celestia stuck her tongue out and jeered. "Well, sister, now that ya turned me into a foal, we're both babies again. So we gotta find Twilight to change us back to normal."

"Right! But …how? We can't talk to grown-up ponies; they all think we just saying baby babble!" Luna whined, now feeling rather bad at turning her sister into a baby.

"Wait, big ponies can't understand us?" Celestia asked, being somewhat concerned.

"No, tey can't. Ya couldn't understand me even when I was shouting at you!" Luna admitted, making Celestia slam a hoof to her face and groan. She then heard her tummy growl. "Otay, first I need a diapee. Ten wets get something ta eat, and after that, we can figure tis out."

"Oh yeah, I gonna diapee ya! Now I get to be the big sister!" Luna giggled as she rushed over to her sister's closet before bringing out a diaper.

The princess of the sun put a hoof to her face as she was somewhat reluctant to go back to wearing diapers and babbled. "Can't believe I got put back into diapees twice!"

"Hey, some would say you're lucky." Luna snickered as she assisted her sister in laying down and having a fresh diaper strapped over her flank. After Celestia had a fresh diaper, the foals headed towards the kitchen to find something to eat.

Fluttershy threw her hooves in the air as she slowly got up, and she turned to see Echo was fast asleep. But what was weirder was that she was now on the ground and was surprised to see that Mango was now a chubby, baby bat pony. Fluttershy gasped and crawled backward, surprised and worried, seeing that Mango was regressed. Who did this?! What happened?! She then turned to see that it was still night outside, and the sun had yet to rise. That meant something was wrong, and she had a sinking feeling that princesses were regressed.

"Mama, ya a baby!" Echo cried as she turned to see that Mango was also waking up.

Mango was surprised to see herself in her regressed state and started to freak out and cry! "Na, no, no! How did I turn into a baby?!"

"I dun know, but now I ta oldest! And ya gots ta listen ta me!” Echo giggled as she clapped her hooves.

"Ya stop, young lady, I still ya, mama!" Mango snapped as she got up, blushing as she waddled over to the changing table and pulled out a diaper.

"Oh, let me help!" Echo squealed, rushing over to help tape her mother in a fresh diaper.

After that, Echo went off to use the potty (again, seeing as she had gone earlier before bed) as Mango waddled over to Fluttershy and gave her diaper a pat, seeing that it was soggy. "Come on. I may be a foal, but I still know how to change a diapee."

Fluttershy simply nodded and let Mango go about changing her diaper. Mango was much clumsier, but she was still knowledgeable, wiping Fluttershy down, powdering her flank, and then making sure the new diaper was snug around the filly's waist. After the change, they all gathered up as Mango mumbled. "How did I turn into a foal?"

Echo bowed her head and mumbled. I dun know how ya became a foal. But I tink if you're a foal, maybe others might be one too!"

Mango nodded as she waddled around, her cheeks flushing red as she got used to the fresh padding around her flank. "Yeah, ya right. We gotta see who else got turned into a baby bat pony." She then led the other foals out of her room (lucky enough for them that their door was slightly ajar, allowing them to get out of their room).

Meanwhile, Fluttershy vaguely remembered suckling on Mango's hoof last night. And she wondered if maybe she had turned Mango into a foal?

The foals continued through the castle and saw that dozens of ponies all over the place were now baby bat ponies, flying around and chasing each other. "How did tis happen!?" Mango shouted again, somewhat confused.

They eventually made their way to the kitchen, where they found a pantry full of fruits of all kinds: Strawberries, mangos, apples, and blueberries. All other fruits were now husks as the baby bat ponies were sucking them dry. They then found the princesses in their baby batpony forms.

Luna turned towards them and shouted. "Hey, Mango! How are ya doing?"

"Obviously not good! What is going on here?!" Mango shouted, surprised to see so many bat ponies flying about.

Luna looked somewhat embarrassed as she said. "I'm sowwie, but I was hungry and came down here..and…well…I accidentally bit a guard for being rude to me. He wasn't listening ta me!"

"Not my fault! I couldn't understand ya!" The other guard shouted.

"Yeah. Then she bit me." Celestia chimed in.

Luna stuck her tongue out at her sister and babbled, "Ten ya bit a noble who was annoying ya!"

"Well, ya bit my other guards! Ya, just a little biter!" Celestia snapped back.

"They was gonna stop us, what else was I gonna do?!" Luna whined. The two continued to bicker for some time before the princess of the night eventually rolled her eyes. "Anyways, we accidentally started turning everypony into baby bat ponies."

Mango slammed a hoof to her face, seeing the foals flying around and causing chaos, "So, what do we do now?"

Luna waddled over and said. "We gotta go find Twilight. She ta only one that can turn us back to normal."

Mango stood up and snapped. "Otay, but that means ya two need to stop biting ponies! We dun need more baby bat ponies running around!"

"Yes, mam." Celestia and Luna chimed together.

Mango then turned to face Fluttershy and added. "That means you too, Fluttershy. It clear ya bite caused me and Princess Luna ta turn into foals."

"Yes, mam." Fluttershy squeaked in embarrassment.

Mango then turned her attention back to Celestia and Luna. "Otay, so we need to find a nursery for these foals. We can't have them running loose! Faust knows if they escape, every fruit in equestria will be sucked dry!"

"Yeah, that would be a big problem," Luna admitted with a blush upon seeing almost all the fruit in their massive pantry was now dried up husks.

"Not only that, all tis juice makes ya pee awot!" Celestia squeaked as she looked down to see her diaper was already yellowed. Soon everypony began bickering amongst each other about what to do and how they would stop the foals from leaving the castle.

Meanwhile, Fluttershy looked rather nervous, feeling somewhat bad at seeing how she was responsible for all of this. But as she looked around the pantry, she noticed a few untouched fruit boxes, and then an idea started forming in her head. "Um, excuse me?" Everypony then turned towards her as she took a few mangos that hadn't been sucked dry and said/"Look, we use tis fruit to lure ta baby bat ponies to a nursery, and we stuff them up. We played with them until tey all tuckered out, and they took a nap; we then made sure tey got diapees on. That way they all sleep and have protection, giving us plenty of time to go find Twily!"

Celestia and Luna blinked, seeing that this was a decent plan, and Mango waddled and hugged Fluttershy and chimed. "Yes, that's a great plan! Ya, so smart Fluttershy!"

The little foal felt rather proud as the princesses chanted, "Fluttershy! Fluttershy!"

"Otay, stop, ya embarrassing me!" Fluttershy squeaked as she threw her wings over her eyes.

Then Echo stood up and said. "Otay, ya and mama should lead! Let's go round up ta baby bat ponies!"

"Yay!" The other foals squealed as they gathered the fruit in the boxes and headed off to get the rest of the baby bat ponies to follow them.

Chapter Four: Herding Baby Batponies!

Luna decided to go to the Grand Hall as she was on the hunt to find the rest of her fellow royal guards. She waddled through the throne room, and it wasn't long before she saw all her former guards (who were now a bunch of baby bat ponies) flying around the place. Despite the ponies being in a regressed form, she was rather peeved they were all just playing around and not trying to help her with their current situation. So she did what she felt any princess should do, coming forward to them and tried to shout in her shrill Canterlot voice. "Soldiers get into formation, now!"

"Yes, princess!" The others all chimed at once. They then flew over as they clambered over Luna, then clumsily got in formation. Luna then slowly waddled over to her fellow guards. Despite the colts trying to look serious, she couldn't help but chuckle at them trying to stand at attention, with some picking their noses while others were sucking on their hooves.

When her dozen or so guards were in formation, Luna cleared her throat and said them. "Listen up! You all may be babies, and ya might not wike ta idea that ya need diapees and stuff, but we gotta get ya protection before you pee aww over ta pwace."

"Nah, uh, dun need diapees!" One of the foals shouted.

One of the guards placed his forehooves over himself and whined. “Yeah, sowie pwincess. No way we gonna weaw diapees!"

"Yeah! We still woyaw guards! We not gonna be humiliated by wewain' diapees!" Another foal snapped.

Luna then chased the foals all over the hall as they ran away from her, even as she shouted! "Wook, ya dun wana make accidents aww ova ta pwace, do you?!"

"We know how to use ta potty!" Every soldier shouted at once.

Luna started to throw a tantrum and then shouted back! "No ya dun! Ya gonna have puddles all over ta pawace! Ya get diapees on right now, ya pwincess commands it!" The foals then started to fly off as Luna looked upwards and shouted! "Hey, ya stop that, now! Ya gotta listen ta me! I ta pwincess of ta night!"

"Otay, pwincess," A colt giggled. "How bout ya gotta play hide and seek with us? Then, when you find all of us, we'll go with you and put on diapees." One of the guards responded.

"Yeah, but ya gotta find all of us!" Another baby bat pony jeered.

"Fine! But if I find ya ya all gotta bettew listen to me!" Luna snapped back as she grumbled under her breath, seeing she didn't have a choice, and started to count down from three. "Three…two…one!" The little filly smirked as she thought to herself how easy this would be. How hard could it be to find a bunch of foals? And that's when she turned around and didn't see anypony at all. "Hewwo? Baby guards? Where did you go?!"

There was no response outside; a bunch of giggling reverberated across the hall. The little foal then slammed a hoof to her face and grumbled. "Tis is gonna be a wot hawdew then, I thought," She shook her head, spread her wings, and flew off to seek out her guards, hoping they hadn't flown off into Canterlot.

As Luna was chasing her guards around, her sister Celestia went upstairs to see a bunch of her former maids and butlers "trying" to clean up a mess of tea spilled all over the place and cake splattered all over the floor. She looked downward with a guilty look on her face seeing that this was what remained of her midnight snack that she'd ordered.

The head maid then looked up; she seemed somewhat embarrassed as she squeaked, "Pwincess Tia, tis is all tea, I swear!"

The princess sighed relief seeing it wasn't a massive accident. But then she turned to see a former butler now reduced to a colt doing a potty dance as he whined. "Yeah, but we need diapees, tough! Ow ewse there's gonna be mowe messies cause none of us can use ta potty!"

Celestia squeaked as the last thing she wanted was to have a bunch of foals peeing all over the place, or worse! She then quickly scrounged up some of the aprons the former staff wore and hastily used her magic to make makeshift diapers out of the fabric. She strapped one around the butler's waist, then did the same with the rest of her staff. She then looked up and said. "Otay, dun wowwie bout that. Stop twying to cwean up. Tats not important."

A maid plopped down on her flank with hooves crossed over her chest and cried. "But it's owa job!"

"Yeah, it's owa job! We made a mess; we gotta cwean it up!" Another butler whined.

Celestia got rather frustrated and snapped. "Ya stop bein' so wesponsibwe! Ya aww need ta follow me, or ya gonna stay wike tis fow a long time!"

"No! We wanna cwean up ta mess first!" The other foals shouted at once.

"Ugh! Ya aww awe too good at ya job," Celestia groaned, slamming her hooves into her face as she was becoming frustrated with these foals. But she also couldn't help but feel a little proud of her staff's willingness to work, even as babies. And seeing that nothing she said made them change their minds, the princess decided to just help clean up the mess. "Fine! We cwean up ta mess, ten ya follow me, otay?"

"Yes, princess!" The foals all chimed at once. Celestia then scurried off to get a mop and bucket for her foals, believing that the faster they got this done, the faster she could find Twilight and get herself and her staff changed back to normal.

As the princesses were dealing with their own problems, Fluttershy followed Echo and Mango through the kitchen, where they found Fancy Pants in the royal kitchen. He was now an adorable baby bat pony, sitting on top of a hoard of the fruit stolen from the pantry. Fluttershy imagined him to look like a dragon on top of a pile of gems with a smug grin on his face (and surprisingly enough, already sporting a rather poofy diaper around his waist).

Two other baby bat ponies slowly came forward as Fancy Pants held up an apple and asked. "Hewwo. Come to trade for some fruit?"

"No, we came to get ya to come with us, so ya dun go biting other ponies!" Mango shouted. "Ya get down from thewe, young cowt!"

Fancy Pants shook his head and asked. "What are ya talking about? I not gonna bite ponies! I just gonna trade these to other regwessed ponies for diapees and stuff."

"That's not nice! Ya gotta share!" Echo whined.

"Yeah, it is! I need some diapees and stuff, and I'm keepin' ta food from being devoured by ya babies!" The little colt shouted back.

Fluttershy bent her head and whispered rather meekly. "…that fruit isn't even yours."

"So what? I find it, so it's mine!" Fancy Pants plopped down on the fruit stack with his tiny forehooves crossing over his chest. "Ya not getting it!"

Mango then got up and scolded the colt. "Ya acting like such a baby! There's plenty of foal supplies; ya dun need to trade ta pwincesses' fruit fow that stuff. Now get down fwom thewe, ow ya goin' in timeout!"

"Bu…bu…" Fancy Pants stuttered and began to whimper.

"No buts! Ya get down, now!" Mango snapped. Despite being a baby, she still had her motherly attitude.

"Oh…otay…" Fancy Pants stammered rather meekly, then clambered down from his stack, seeming to have never been scolded like that in a long time.

Fluttershy couldn't help but giggle at the scene, then waddled over to the stack and sniffed it. She then heard the princesses and the other foals crying; it sounded like they were having trouble rounding up their foals. She then turned towards Echo and Mango. "Otay, two wets, make a bunch of juice and get a bunch of sippy cups. I think tis piwe of fruit wiww wowk for what I have planned."

It's been almost an hour since Luna started looking for her guards, and so far, she couldn't find a single one. Luna started to get frustrated as she pulled her mane and shouted, "Wiww you aww just come out already?!"

"Hehehe, ya can't find us!" The foals all jeered at once.

"I swear, for punishment, I'm gonna make ya aww wear diapees when ya go back to being big ponies! I mean it!" Luna shouted. But then she sniffed the air, smelling the scent of fruit. She began to drool a little as her pupils widened.

Luna then turned to see Fluttershy coming over as she had a wagon field to the brim of sippy cups filled with fruit juice, and she cooed. "Come on, sweeties. Who wants some juice?!" It didn't take long for the whole regiment of baby bat pony guards to fly down from the rafters and go to the wagon, snatching up a sippy cup and sucking away to their heart's content.

Luna just stared in disbelief and shouted. "Ya was aww hiding up thewe the whole time?!"

"Yeah, where else would we be hiding? We bat ponies!" One of the colts responded rather with a smug grin. "Nopony ever tinks to wook up!"

Everypony started giggling as Luna pulled at her mane and roared, putting a hoof to her face. "Ugh! I felt so stupid! How did I not think of that?!"

Fluttershy shook her head as she lured the bat ponies up the stairs, as the rest of the foals followed her. They then came upon Celestia, who was still helping the other foals clean up all the tea and cake. But they soon stopped what they were doing as they started sniffing the air. Their pupils went wide, and the horde of baby bat ponies fluttered off, following the aroma of the fruit juice.

The bat ponies and Luna and her bat pony soldiers joined them. They eventually were herded towards a giant nursery. There Fluttershy had a stack of diapers and a container of foal powder and went about changing all of them (with help from Mango and Echo). She then slowly strapped them up one by one in a diaper while Mango went about and plopped sippy cups full of apple juice into their mouths. Soon the horde of baby bat ponies were taped snuggly in thick pairs of diapers while sucking away on their sippy cups filled with fruit juice.

Seeing the dozens of baby bat ponies all sleeping, Mango gave a sigh of relief. "Seems they were aww tuckered out. Tats a relief. Wuna knows, if tey wewe aww cwanky tis wouwd be a wot hawdew.”

"Tey bettew be tiwed! I spent wike an houw just playing hide and seek with them," Luna wheezed, seeming to be out of breath from flying around for nearly an hour. "And they totally cheated."

"Ya wucky, ya got to have fun. I had to spend an hour helping ta butwews and maids cwean up a giant mess," Celestia yawned as she tapped a hoof to her face and flapped her tiny batwings. Seeing that all of the other foals were fast asleep, she scratched the back of her mane and asked. "Otay, so what do we do now? Sowwie, I gettin' sweepy."

The little princess gave another yawn as Luna took the opportunity to plop a sippy cup full of strawberry juice into her sister's mouth. "Hey, tats otay. Ya, not used to stayin' up with a moon out. Ya need ya sweepies."

Celestia simply nodded as she suckled away on her sippy cup and seemed too tired to make a fuss.

Fluttershy couldn't help but dawwat the princesses acting so adorable and secretly wished they could stay this way so that she could babysit them as an adult. But she needed to keep her mind focused on getting herself and everypony else back to normal. She then responded to Celestia's earlier question. "It's simple, weawwy. We just gotta go to Ponyviwwe and find Twiwy, then we have her tuwn us back to nowmaw. And we also have to get these babies back to adults as weww."

Celestia nodded and gave another cute yawn as she flapped her tiny wings and said. "Yeah, tats a good plan. Hopefully, she got my wettew, but I'm too tired; I gonna go night night."

"Otay big sis, ya go to sweepies, we'll find Twily and get us aww turned back to nowmaw." Luna sweetly whispered as she led her sister to a sleeping mat and helped tuck her under the covers.

Echo also looked somewhat exhausted as she flexed her wings and yawned. "I'm tired too. Being helpful and gwown-up is exhausting. Mama, can I go night nights?"

"Otay, you and Pwincess Tia stay hewe and be good giwws, and keep these babies fwom escaping ta Cantewwot. And if they wake up, teach them not to bite ponies, otay?" Mango cooed as she patted her daughter on the head.

"Otay, Mama, I will! They need to not bite ponies tats bad." Echo mumbled sleepily as she went off to sleep with the other foals.

Meanwhile, Mango gathered supplies for the journey: Diapers, wipes, foal powder, sippy cups full of juice, and a ton of fruit she'd chopped up into pieces were all placed into a diaper bag. She then led Fluttershy and Luna towards the front doors of the palace as they came out to the night-filled streets of Canterlot. The trio looked rather silly wearing nothing but diapers (especially when one had a diaper bag over her shoulders).

The princess of the night turned her attention toward Fluttershy and asked. "Ya ready? Tis is gonna be a wong fight."

For some reason, Fluttershy felt much more confident in herself in her baby bat pony form, even with a diaper around her waist. She seemed to enjoy being this way, and the city under the night blanket appeared to engage some primal instincts in her. The little chubby bat pony spread her tiny leathery wings and said confidently. "I weady, wets go!"

"Ugh, I should be askin' myself tat. I dun know if I'm gonna make it." Luna grumbled as she still felt achy from playing "hide-and-go-seek" from before, but she was determined to get this entire matter resolved. The three baby bat ponies then unfurled their wings, shook their padded butts, and flew off into the night as they flew together into the dark streets of Canterlot, heading towards Ponyville.

Chapter Five: The Truth is Revealed!

Fluttershy, Luna, and Mango were all now flying down toward Ponyville. Having flown for miles, the three fillies were quite tuckered out as they finally landed on solid ground. Mango turned towards the others and asked. “Awe, you two awwight?” The other foals nodded, then waddled towards Twilight’s library. Fluttershy was rather relieved since, although she’d had fun being a baby bat pony, she was looking forward to becoming an adult again.

They then went up to the door, knocking on it, and asking for help. But as the door opened, standing before them was Spike with two baby bat ponies crawling all over him. The little drake looked utterly exhausted with not only baby Trixie on top of his head but what made everypony gasp: The other foal was Twilight!

The dragon blinked and groaned. “Oh no! You all got turned into babies too?!”

“Mama Twiwwy is a baby again!” Trixie squealed in delight as she bounced on Spike’s head.

“Go figuwes. I used to it at tis point.” Twilight kicked about in a diaper as she responded in a rather unphased tone.

Spike then bowed before the baby princess. “I’m sorry, Princess Luna. Twilight suddenly turned into a baby bat pony out of nowhere. She got angry at me because I couldn’t figure out what she was saying. Then she went off alone while you and Princess Celestia sent me letters. I would’ve written back, but I had to find Twilight first. I couldn’t risk her getting hurt.”

Luna nodded, seeming to understand. “Is otay, Spike. I forgive ya for not responding. Seems like ya had ya claws full.”

Spike blinked, seeing that he couldn’t understand a word Luna said. He then turned to Trixie and asked. “Um…Trixie, can you translate?”

Trixie nodded and said, “Lulu just said she fowgives ya, and ya wouwd wook cute in a diapee.”

Spike's cheeks flushed red as the baby princess scowled and shouted! “No, I didn’t!”

“Now she’s saying she just peed hew diapee,” Trixie replied.

“Twixie!” Luna whined, blushing as she threw her hooves over the front of her diaper. She didn’t know what was worse: The fact that she actually had peed herself or that Trixie had pointed it out.

Spike rolled his eyes as he took the foals into the library (which was still covered in a pink foam-like material) and changed each of their diapers (as Mango and Fluttershy were also wet, and heavily so), then he said. “Ok, listen. I can't understand a word you baby bat ponies are saying. Luckily for us, Trixie can still understand baby babble, so she’ll translate things. I know she can be lying about some stuff you're saying; she’s been doing it to Twilight all night.”

Twilight bowed her head and grumbled under her breath. “But she’s aww I got untiw we get ya back to nowmaw.”

They all nodded as Spike got them up on their hooves.

Then Twilight came over and said. “Wook, I wouwd wove ta help tuwn ya aww back ta nowmaw. But even if I couwd use ta amuwet, which I can't since I a baby, it’ww onwy tuwn ya back to aduwts. Ya wiww aww stiww be batponies.”

Mango’s cheeks flushed pink. “Weww, that wouwd be otay for me; I alweady a batpony.”

“Otay, but tat stiww weaves the west of us,” Twilight pointed out. “We would also need to find a unicorn or other ponies powerful enough to tuwn us back to nowmaw,” She turned to Luna and sighed. “Seeing ya is a baby, I assume ya sistew, Pwincess Tia, got regressed again as well?” Luna nodded as Twilight slammed a hoof into her face. “Gweat!” She then turned to Trixie. “How’s ya magic? Stiww wowking on it?”

Trixie blushed as she confessed. “Wook…even when I was an aduwt, I was only otay with magic. And if I mess up with ta amulet, I might just make tings worse,” Everypony else slammed their hooves in their faces, and Fluttershy sighed as she shook her head.

Spike plopped down on his butt and whined, “what am I going to do now?! I’m barely holding on to caring for these two! I can’t care for an entire kingdom of babies, especially baby bat ponies!”

Mango sighed. “Gweat…so magic is out of ta question. We need another plan.”

Fluttershy tapped a hoof to her chin and then asked. “Hey, what about Zecowa? She may be a toddler, but I heawd she’s stiww good at making potions.”

Twilight had to resist the urge to slam her hoof into her face. “Wight, she can help us! She’s in pweschoow now, fwom what I heaw! Why didn't I tink of tat?!”

A short time later, the group of baby bat ponies waddled through what felt like a rather empty town (with Spike following them with a diaper bag). It was still night, technically, but it was odd that nopony was out and about. It made Ponyville feel rather empty. But they couldn’t worry about that.

They continued through the town until they came to Sweet Apple Acres, and there they knocked on the door, and Zecora opened it.

The toddler zebra stood there smiling, wearing no diaper as she was now fully potty trained. “Oh my gosh! I can’t bewieve ya aww babies!” She squealed in delight at seeing a bunch of ponies! She hugged Twilight and the rest of the regressed ponies. Then after her hugs, Zecora turned her attention to Trixie and chirped. “Good ta see ya, best fwiend!”

Zecora then started to ruffle her friend’s mane, making Trixie giggle and kick about as she chirped. “Otay, Zecowa, ya can stop!”

“Ya aww need a cuwe, don’t ya?” Zecora asked as the toddler zebra stopped. “I don’t tink any of you want to stay as babies; I’m suwe,” The filly chirped as she led the group into her home, where the Apple Family was. Miraculously, they were all unaffected by whatever had afflicted Twilight and Trixie.

“Hey Zecora, ho-” Applejack began. But before she could finish, the farm mare looked downward. There, she gasped upon seeing the rest of the baby bat ponies and cried. “Oh, come on! Will this age regression pandemic ever end?!”

Big Mac chuckled, scooping up the foals and nuzzling them as he placed them in highchairs while Spike explained. “From what Trixie’s told me. There’s a new curse going on that’s turning ponies into baby bat ponies.”

“Oh, that’s what happened to Fluttershy!? She was supposed to help us with the bats attacking our orchard.”

Fluttershy nodded as she cleared her throat and had Trixie translate her journey to Batponyville; she went to Canterlot, where Princess Luna and a bunch of castle staff turned into baby bat ponies.

Applejack was surprised by the story. If it weren’t for the fact there were four baby bat ponies in front of her; she wouldn’t have believed it.

After Fluttershy finished, Princess Luna then explained to Trixie, who talked to Applejack about how they needed Zecora to whip up a cure. They did their best to convey their situation through Zecora to Applejack.

“Um…I see; just weave it up to me!” The zebra exclaimed; she then took out a book of old potions she’d used to make when she was an adult. She then found the accurate ingredients for a potion that would turn them back into adults, reverse the bat pony DNA, and turn them back to their original tribe.

The baby bat ponies all gave some saliva for DNA and hair.

Zecora then began mixing them with other ingredients (with Applejack helping the zebra read out what she needed).

Meanwhile, Big Mac went out to get some more foal supplies. When he returned, he quickly rushed back inside with a worried look on his face as he cried! “Uh, guys? You’re not the only baby bat ponies!”

Everypony went outside, and they all saw tons of other townsponies all now baby bat ponies, who were all flapping towards Sweet Apple Acres. They all looked rather hungry, their mouths drooling as they rushed towards the orchard.

Applejack then stood up and shouted. “Oh no! I ain’t gonna let a bunch of baby bat ponies devour my apples, let alone the entire orchard!”

Fluttershy then turned her attention toward the baby zebra and said. “Hey Zecowa, ya just go and make ta potion! Awso, have Appwejack go make appwe juice!”

“Right!” The zebra nodded. “Mama Appwejack, go make some appwe juice. I gonna need ta DNA from every baby batpony,” Zecora explained.

“Just make ta base potion. Lulu, Mango, and I will herd tese batponies; just wike we did befowe.” Fluttershy explained.

Zecora and Applejack then ran off to go get the apple juice and potion ready.

Fluttershy, meanwhile, led Luna and Mango to the apple orchard, where they grabbed apples and cut them open with their sharp teeth. They then all started to lead the foals inside the farmhouse. The little yellow-coated bat pony led the other foals that had accompanied her, and with Mango’s help, they all strapped the herd of baby bat ponies into diapers.

Luna took some drool and hair from each pony to Zecora.

Zecora worked on the potion, mixing one by one for each afflicted pony.

Applejack had little sippy cups filled with apple juice mixed with the potion plopped into their mouths.

Everypony waited impatiently as the baby bat ponies slowly turned back to normal. Not only were the baby bat ponies turned back to adults, but they were back to pegasi, unicorns, and earth ponies.

Everypony took a sigh of relief as Applejack wiped her brow. “Thank Celestia; the orchard was saved.”

Big Mac laid back in his chair and gave a sigh, “Ey’yup!”

Fluttershy and the remaining foals were throwing Zecora in the air while shouting. “Hip! Hip! Hooway!”

“Yay, I did it!” The little zebra squealed. “I got my potion-making skills back!”

“It works! It actually works!” Twilight exclaimed, hugging the toddler zebra, who lifted her head up proudly at her accomplishment.

“Otay, we shouwd pwobabwy turn back ta normal now,” Fluttershy whispered.

Mango nodded as she bounced up and down on her diaper and said. “Yes, being a baby was quite an experience. But I need to turn back ta nowmaw to raise my foaw.”

“Don’t ya worry,” Zecora snickered as she threw her hooves up and exclaimed, “Tewe’s pwenty of potion for evewypony!”

But then, as they all went to where Zecora had set up a cauldron to brew her potions, upon coming upon it they found that the cauldron, which had the rest of the potion they found, was gone!

“Ta potion is aww gone!” The zebra whined as Fluttershy then saw out of the corner of her eye somepony flying off.

Fluttershy didn’t have time to tell anypony else what she saw as she chased after the mysterious pony. She continued to fly. Chasing the mysterious pony towards the apple orchard where she’d first regressed to see in the light of the moon. Fluttershy gasped in surprise to see the pony she was chasing was none other than Echo, who had a giant jug filled with a bright green liquid.

The toddler filly was meeting a pink-coated unicorn foal. Fluttershy didn’t know her and hadn't seen her, but Twilight warned her about this foal who had turned Trixie and Rainbow Dash into foals. It was Starlight!

Chapter Six: The End of the Baby Batpony curse

Fluttershy was sitting outside behind an apple tree, looking at what appeared to be a meeting between Echo and Starlight. The little filly had no idea what was going on between the two, but whatever it was, she decided it was best to wait and see what happened. She was surprised, however, that Echo had apparently been in cahoots with Starlight this whole time.

Little Starlight was sitting on her padded seat with a smile as she exclaimed. "Tanks so much for ta potion. Tis awmost ruined owa pwans!"

Echo was giving Starlight an angry glare as she asked. "I tuwned ta pwincesses into baby ponies and gave ya ta potion wike ya wanted. Now ya gonna turn my mama back to nowmaw, wight?"

"Of couwse!” Starlight replied. “You did evewyting we asked, and now we can take Twiwight and the pwincesses, and you can keep Fwuttewshy as ya baby sistew," Echo looked down, ashamed for her actions, as Starlight patted her head. "Hey, dun feew bad. Tis is what ya wanted, wight? A baby sistew, wight?"

The little filly looked downward and then said. "Yeah, and it was fun having one. But it feews wong now, wike we ta bad guys." Echo then started to cry as she put her hooves over her eyes, appearing to feel guilty for helping Starlight.

The baby pinkish-purple coated unicorn trotted over and gave Echo a pat on the back, then whispered. "Yeah, it can seem tat way. But ya want Fwuttewshy to be ya baby sistew, wight?"

"No!" Fluttershy exclaimed and emerged from hiding! She then unfolded her wings and shouted. "Echo! Don't give hew tat potion! She’s eviw!"

Starlight threw her hooves into the air and exclaimed! "Come on, Echo! If ya give me ta potion, Fwuttewshy wiww be your baby sistew fowevew!"

"Fwuttewshy?!" The little filly cried as she turned to face her.

The yellow-coated baby batpony flew over and snapped at Echo. "Wisten ta me! I fowgive you fow tuwning me into a baby batpony. But ya gotta see by now tat tis is wong! If you wet Stawwight take that potion, my fwiends and I can nevew tuwn back to nowmaw! We impowtant to Equestwia!"

"Dun wisten ta hew! Wisten ta me now!" Starlight shouted as she lowered her head with her horn glowing. “Give me tat potion!

Echo turned to Fluttershy with a worried look as she asked. "Ya not mad at me, awe ya?"

Fluttershy shook her head and continued. "No, of couwse not. I understand why you tuwned my fwiends and I into baby batponies. Ya just wanted a baby sistew, wight?"

Echo nodded. "Tats wha happened. Stawwight twicked me into thinking turning ya into a baby batpony was the onwy way I couwd have one. I weawwy wanted to be a big sistew, but my mommy said she can’t have mowe babies. I ta onwy one she'll be able to have."

"No, stop listening to hew, Echo!" Starlight whined as she started to throw a tantrum. "If ya dun give me ta potion ten ya will nevew have a baby sistew! Fwuttewshy wiww weave ya fowevaw!"

Echo turned back to face the yellow-coated baby batpony and then asked. "If ya tuwn back into a big pony, ya won't weave me, wight?"

Fluttershy paused as she had to make sure whatever she said would convince Echo to give her the potion. But at the same time, she couldn't lie to the foal. She then waddled over to the baby batpony. "Wook, I won't be ya baby sistew, but I wiww always be ya big sista in a way. And I'ww come to visit ya whenevew I can."

Echo gave Fluttershy a puppy dog eyes look and asked. "Ya pwomise?"

Fluttershy put a hoof over her chest. "I pwomise."

The little filly nodded, prepared to give the potion to Fluttershy. But Starlight suddenly pounced on top of her! As the two tussled about, Echo was able to kick the jar full of Zecora's potion toward Fluttershy and shouted! "Take ta potion! Give it ta ya fwiends, huwwy!"

Fluttershy snatched the potion and put it aside as she was going to go help Echo. But before she could do anything, Starlight disappeared with Echo, leaving the baby batpony speechless. Echo had been foalnapped! Fluttershy lowered her head with tears welling in her eyes and muttered. "When we gwow up, we gonna save ya, Echo!" She then took the jar and flew off into the air, heading back to the Apple family’s farmhouse.

Fluttershy flew back to the farmhouse, where Twilight, Luna and Mango were all waiting for her.

"Fwuttewshy, are ya otay?!" Twilight cried out as she ran over to meet her friend.

Fluttershy was in tears as she hugged her friend, and a wave of emotion came over the little filly as she started to bawl into her hooves.

Luna then trotted over to see the jar full of Zecora's potion and gasped! "Ya did it! Ya got ta potion!"

Fluttershy sighed as she explained. "Yes. But I have to say tat Echo stawted the batpony cuwse, and was ta one who tuwned me into a baby batpony."

"It was Echo?!" Everypony shouted all at once in disbelief!

The yellow-coated foal cleared her throat and then continued. "Yes, Echo. But it wasn't aww hew fauwt. Stawwight Gwimmew twicked hew into thinking that to keep me as hew baby sistew, she had ta do whatever Stawwight said. She was sad ‘cause she wanted to be a big sistew, but couwdn’t ‘cause her mommy couwdn’t have mowe foaws."

Mango looked somewhat scared and worried, sweat coming down her face as she stammered. "I…I see…but whewe is she?! Is she ok?!"

Fluttershy started tearing up. "No, she was taken by Stawwight when I convinced hew to give me ta potion."

The motherly batpony roared in anger and then shouted! "Weww, if we find tis Stawwight, I gonna ki-"

"-Um, Stawwight's a baby too." Fluttershy mumbled under her breath.

Mango cleared her throat. "Wet me wephwase tat," She then shouted! "When I find hew, I'ww give hew a vewy big spanking! Hew wump’s gonna be wed and swoe fow days!"

Luna nodded. "Otay, so what do we do? How do we save Echo?"

Fluttershy groaned under her breath. "Ta biggest weason why Stawwight is doing tis is because we can stop hew with my fwiends and I. Ta onl\wy way we gonna get hew back is if Twiwight or I twade ouwsewves and stay as baby batponies."

Everypony else were looking at each other with worried looks on their faces as Twilight whispered. "Fwuttewshy is wight. Stawwight is using time twavew and can onwy stay hewe fow so wong. I bet she's stiww somewhewe in Sweet Appwe Acwes, waiting fow one of us to find hew."

"Otay, but…tats not a good idea even if ya gonna sacwifice yaself for my daughter. If ya get taken, Stawwight might have aww ta ponies in Equestwia tuwn into babies." Mango explained.

Luna held up a hoof. "Wait, howd up! Tis Stawwight sounds pwetty awwogant. Why don't we set up a twap?!"

"Wight, sounds wike a gweat idea!" Fluttershy replied with a smirk as they huddled up and started to talk about creating a trap to save Echo.

Meanwhile, back in the apple orchard, Starlight had Echo tied up as she was waddling back and forth in front of her, cursing under her breath. "Ta baby batpony cuwse Midnight cwafted wowked pewfectwy! But ya ruined owa pwans, Echo! Aww, ya had ta do was give me tat stupid potion, and I would've secured my victory!" Starlight whined.

Echo stuck her tongue out and jeered. "Weww, Fwuttewshy was way smawtew ten ya, and wiww come to wescue me!"

Starlight gave a hearty chuckle. "Tats what I'm waiting fow! When Fwuttewshy wetuwns and if she's stiww a baby, I'ww twade you for hew, and I can continue my pwans!"

"Weww, guess you wewe wight!" Starlight turned to see Fluttershy standing up proudly (despite still being in diapers). "Ya wet Echo go, and ya can take me instead!"

"Fine, it's a deaw!" Starlight snapped as she then ran right at Fluttershy! But the baby unicorn then cried out in horror as she was picked up by the seam of her diaper. Mango now had her as Fluttershy flew towards Echo and rescued her.

Meanwhile, Twilight (now an adult alicorn) flew over and hoisted Starlight in a magical time bubble as she shouted. "You won't get away this time!"

Starlight roared in defiance. "Ugh, fowget tis!” She tried to teleport, but her horn simply fizzled, preventing her from leaving as she kicked and whined. "Why can't I weave?!"

Twilight gave the filly a smirk. "You forget, I worked with a time agency, and they gave me access to a spell called the time bubble. As long as you're trapped in this, you can't escape."

The baby unicorn laughed. "Ya may have me now, but I awweady set tings in motion fow ta future! You ow one of youw friends wiww end up as a baby fowevew, I sweaw!"

Twilight levitated the foal towards her as she jeered. "Well, we'll just have to wait and see, huh?" She then levitated her amulet as she continued. "And if you happen to turn one of my friends or me into a baby, as long as I have my amulet, I'll just turn them back to adults. Pity I can’t extend that luxury to you. Seems like you’ll be the one who’s a baby forever." Twilight then trotted off with her captured pony.

Fluttershy then wrapped her leathery wings and hugged Echo close to her chest. "I'm just gwad ya safe!"

Mango then hugged both foals and cried. "Oh, Echo! I would be so mad at you, but I'm just glad you're okay!"

The baby batpony looked downward and mumbled. "I sowie for tuwning ya and Pwincess Wuwu into babies…I…I taught Stawwight was gonna turn ya aww back ta nowmaw when Fwuttewshy officially became my baby sistew. I should've seen that Stawwight was just twicking me."

Mango took her daughter into her hooves and hugged her close as she cried, "Dear, you're only three, and yet you figured out that Starlight was using you," She then bent down and hugged her daughter and cried. "I'm so proud of you! You’re growing up so fast! I definitely can’t justify keeping you in diapers anymore."

After Luna was turned back to normal, Twilight gave the potion to her so she could turn Princess Celestia and the rest of the castle staff back into adults. She then watched the sun slowly rise, and ponies were doing their business, with most thinking the batpony curse was just a bad dream.

Twilight then turned to Fluttershy as she asked. "Are you sure you don't want to turn back into a pegasus?"

The yellow pegasus was now an adult again but remained a batpony. "Yes. I…I want to live with the bat ponies for a while and with Echo. I want Echo to know I'll be there for her. And this way, I’ll understand their culture better."

The alicorn nodded. "Well, I think that's a great idea. We could use more information about batponies and how they function. Princess Luna was the only other source we had until now."

"How about you?” Fluttershy asked. “Are you going to be ok with Starlight? That’s another powerful unicorn foal you’ll have to deal with."

Twilight snickered under her breath. "Yeah, I’ll manage. I have her upstairs, trapped in the time bubble spell. But I'll still change her diapers, feed her, and care for her as if she were my daughter.”

Fluttershy dawwed. "Well, I hope she can have a change of heart while you care for her," She then went out and picked up baby Discord, who bounced on his diapered butt as he shouted. "So, ya was a baby batpony tis whowe time?! Teww me aww about it!"

Fluttershy giggled as she nuzzled Discord and cooed. "Ok, I will, but you gotta promise me you'll play nice with baby Echo. "

"I wiww, Mama! I pwomise!" Discord squealed as he bounced onto her back, and she flew off with the sun rising.

Fluttershy was getting somewhat drowsy. Her entire sleep schedule had been nocturnal, but she'd remain awake until she could crash at Mango's house.

Epilouge: Fluttershy's Vacation

“Fluttershy? Fluttershy?!” The yellow coated batpony yawned as she slowly woke to see Echo nuzzling into her belly. The two were hanging upside down on a banister in Echo’s bedroom with the older bat pony's tail tied around it. She held Echo close to her chest, underneath her wings. The baby batpony peered upward towards Fluttershy with her big, round, adorable puppy dog eyes and said. “Hey Fwuttewshy, I gotta go potty.”

“Ok, come on,” The mare chirped. She then flew down from the banister and escorted the toddler through the house to her plastic training potty. Fluttershy then sat the little filly down, and waited patiently for her to go potty. “Are you sure you don’t wanna use the big potty? You know, the toilet?” She asked the baby batpony.

Echo shook her head. “Mommy say she gonna teach me how to use it watew, when I aww done being punished fow what I did.” And soon, she did her business and waited patiently for Fluttershy to clean her up and empty out the potty.

After wiping Echo down, Fluttershy took her to the kitchen where Mango was busy making breakfast. The bat pony was sporting her dark blue armor and was already ready to go do her duties. She then looked over her shoulder and flashed a smile. "Good evening, Fluttershy!"

"Good evening, Mango." Fluttershy chirped back as she placed the filly onto her booster seat at the kitchen table. Echo’s mom then gave her a bowl of oatmeal with mashed fruit. She then placed a stack of pancakes on the table with berries baked into them.

The aroma of the food was overwhelming as Fluttershy’s mouth drooled down her chin as her bat pony senses were kicking in. The yellow coated batpony placed a hoof over her face, being rather surprised to see Mango had made so much food. “Oh, Mango you didn’t have to do all of this!”

Fluttershy queaked in surprise when Mango came over and hugged her. “Oh Fluttershy, it's perfectly fine. I’m just glad you're helping me with Echo. Trust me, it's great having a babysitter. It really helps."

"Yeah, Fwuttewshy is a gweat big sissy!" Echo cheered as she clapped her hooves together.

After Mango and Fluttershy broke off their hug, the yellow coated batpony then sniffed the stack of pancakes on the table, with drool coming down her chin as she went and started to devour them.

Echo’s mother also sat down with some pancakes and coffee. She then looked over at Fluttershy and asked. “Now that all that craziness with Starlight is over, how are you doing?”

The yellow coated bat ony clapped her hooves together. “I’m doing great! I have a job here helping ponies with their pet bats and owls. And I made a friend with the pony that runs the petcare center.”

Mango chuckled as she replied. “That’s wonderful to hear. Echo keeps asking for a pet bat, but I think she’s too young to own a pet.”

Echo started to throw a tantrum and shouted. “Mom! I not too young! I want a bat!"

"Maybe when you're older, sweetie." Mango cooed as she continued to eat her meal.

Then Fluttershy's ears twitched, hearing the pitter pat of tiny feet of baby Discord, wearing his thick diaper as he toddled into the kitchen. Fluttershy couldn’t help but smile as she came over and held out her hooves as baby Discord toddled into them while shouting. “Mama!”

"Hi, sweetie!' Fluttershy picked her adopted son up and hugged him and nuzzled him making Mango daww. “Aww, he’s so cute.”

“Yes Discord is, but he can be such a troublemaker,.” Fluttershy then plopped him into the highchair and then went about spoon feeding him some mashed fruit mixed with oatmeal. After that she turned to Echo and asked. “So, I know it’s hard to discuss, but how did you turn me and Princess Luna into foals?”

Echo looked down as she explained. “Weww, Stawwight came by aftew I ovewheawd Mama couwdn’t have any mowe babies. I wan a baby sistew so bad and Stawwight towd me ya was pewfect.”

Fluttershy nodded as she then took out a bottle of milk, and plopped it into Discord’s mouth as she said. “Ok, continue.”

Echo looked downard. “She ten gave me a potion tat, when I dwink it it makes me dwoow, and tuwn ya into baby batponies.”

Fluttershy was rather surprised that Echo still has this potion. She wondered if maybe Zecora could use it to make more cures, just in case Midnight tried using it again. Fluttershy then asked “I see. Do you have the potion?”

Echo then gave Fluttershy what was left of the potion in a vial. Fluttershy then stowed it away, feeling relieved Echo still had it. The little bat pony filly continued. “I…I taught it wouwd be nice for ya to be a baby batpony, but I saw I was wong,” She whimpered. “I sowie.”

“Hey, it’s ok. I forgive you,” Fluttershy whispered sweetly as she came over and nuzzled her. “I had such a great time being here, and seeing you grow into a big filly.”

Echo smiled and hugged Fluttershy tightly, and Fluttershy wrapped her wings around the little filly and held her close. That was until Sonic trotted into the kitchen wearing a flight suit, yawning as he asked. “So, you’re going to drop the babies off at nightcare?”

Fluttershy got up with the two babies now on her back as she chirped. “Yes. Is that ok?”

“Of course it is!” Mango exclaimed as she trotted over giving Fluttershy a peck on the cheek and then Sonic came over and nuzzled the foals.

Fluttershy then went about strapping the two into a double seated stroller and making sure the straps were snug around her charges.

They then all set out the door as Sonic and Mango flew off to their jobs, meanwhile Fluttershy pushed the two babies down the street of Batponyville. The place was still as it was when she had left a few days ago, with batponies going about their night, flying around or squeaking at each other. Fluttershy could see the tons of bats and owls being herded about by other batponies for their nightly flies.

But when they went through the markert, Fluttershy senses were once again overwhelmed by all the fruit being sold: Mangoes, pineapples, apples, berries, pears. All of them just made her mouth drool and she had to keep herself from diving at them like a filly.

That was when Fluttershy noticed the weight of the stroller had lessened and saw that the foals were gone! It didn’t take Fluttershy long to figure out Echo and Discord had left the stroller and were now going to a barrel full of mangoes, diving into it. Fluttershy hissed in anger as she flew over, grabbed the two foals out of the barrel and snapped. “Echo! Discord! You two get back into the stroller, now!”

“Yes, Fwuttewshy.” The foals mumbled as they climbed back into the stroller. After strapping them back in she paid a rather plump batpony, apologizing as she started to push her charges down the street at a quicker pace. Eventually she made it to Nightcare where she met the old nanny batpony, the same one who’d cared for her when she was a baby batpony not too long ago.

“Oh, hello! You grew up rather fast, huh?” The nanny commented.

Fluttershy couldn’t help but snicker. “Well, I wasn’t actually a baby batpony, but a pegasus named Fluttershy.”

“That’s good to hear. And I see we have Echo and…who’s this?” The nanny asked, peering down at Discord with curiosity.

Discord held up his claws and exclaimed. “I Discowd, ta wowd of chaos!”

“Awww, he’s so cute!” The nanny squealed, taking Discord and hugging him.

Discord wiggled and squirmed as he whined. “Stop it! Didn’t ya heaw me?! I ta wowd of chaos!”

“Oh of course you are!” The nanny snickered as she placed him back down and turned to Fluttershy. “Well, Fluttershy, how long are you going to be here?”

Fluttershy took out her purse then gave the mare a sack full of bits as she explained. “Well, maybe for a week or so. I just want to understand batponies more,” The nanny nodded as Flutetrshy bent down to her charge and cooed. “Now Discord, you be on your best behavior. No using chaos magic while I’m gone, ok?”

“Yes, Mama.” Discord chirped as he gave her a kiss on the cheek and went off to play.

Fluttershy then turned her attention to Echo and hugged her. “You be good to and watch out for Discord. Keep him out of trouble.”

“Of couwse, I'ww be ta big sissy!” Echo chirped as she gave Flutetrshy a peck on the cheek before flying off into the play area.

Flutterhsy then waved goodbye once more before heading out of the Nightcare. Fluttershy then flexed her wings and soared off to her temporary job with a smile, seeming to enjoy how batponies were so much nicer than some other ponies she knew. The temptation to stay here was great, but she knew she’d have to return to Ponyville eventually, seeing as she had her own duties to take care of. But for now she’ll treat this as a nice vacation.
