“Got any fours?” Spike asked as he stared at the cards in his claws.

Discord looked at his cards thinking for a moment. “Nope.”

Spike rolled his eyes as he pick up card from the pile looking around the reading room again. “I watched Pumpkin draw a tree the other day. Oh and got to teach her how to play patty cake.”

“Oh that’s cute. I got to house sit some of Fluttershy’s animals the other day.”

Spike raised an eyebrow. “And you didn’t change their heads or anything?” He ask for another card watching Discord look up with a glare.

“Why of course not! Fluttershy trust me with her animals. I'm more than responsible to pet sit. Unlike you?”

“That was one time,” Spike protested. “I’m responsible enough. I keep this castle clean all by myself.” He continued.

“Yes yes maid spikey wikey.” Discord teased, making a frilly maid outfit appear on the dragon for a second.

“Hey ugh!” Spike blushed as he tugged on the seams of the dress only for it to vanish a second later. “What are you trying to imply?”

“Well you didn’t help with that big battle earlier.” Discord slid over patting Spike head.

“I was keeping foals safe during the attack.” Spike retorted. “The hospital had just been the safest spot for kids to hide during the breakout at Tartarus!”

“You handling foals? I’m not sure you could. After all you are a baby yourself” Discord mocked, pinching his chubby cheeks. Spike groaned smacking Discord’s claws away from his face as he growled in anger,“I could handle taking care of a foal. I even changed a few diapers once when I was helping Pinkie!”

Discord peered over the stallion. “But could you handle it on your own?”

“Yes, i’m not a kid, i’m like twelve. Nearly a teen by pony standards!” Spike spat back with a gruff.

A grin spread across Discord’s muzzle.” Well, how about we make a bet...”


Twilight was exhausted panting and sweating all over with her horn sparking. Her other friends were not doing much better mumbling “oh my Celestia, that was hard. My horn can’’t even fizzle.”

Rainbow Dash groaned hearing her wings cracking. “Ugh helping Celestia fight those escaped monsters from Tartarus was crazy hard! I barely got any sleep with my wings aching all night.”

Rarity was crying, “I lost a lot of my favorite dress-ss-sss-ss.” Twilight pat her on the back trying to calm the distressed fashionetta down.

Applejack got up and groaned as she rubbed the back of her neck. “I wish we could have a break from saving Equestria. I mean i’m still in the middle of apple bucking season for crying out loud!”

Fluttershy whimpered,”y-ye-yeah, I really need time off those monsters were-s-sc-scary.”

Pinkie Pie bounced over and chirped “oh come on! We‘ve saved Equestria a dozen times already! We’ve beaten Tirek, nightmare moon, Discord, Starlight Glimmer twice, Tempest and the Storm King, that big bugbear…”

The rest of the mares just looked at Pinkie Pie with exhausted looks all letting out a joined goan.

Starlight Glimmer turned to her tired friends, “you know there could be a spell to help us relax?”

Twilight got up, “yeah maybe but what spell…”

Discord burst out of a flower pot scaring the group half to death. “Well I couldn’t help but overhear your little conversation. I think I might just have a way to help all of you relax.”

“Does it involve a weekend spa?” Rarity asked, looking at her chipped hooficure.

“Nope,” Discord smirked.

Twilight eyed him suspiciously. “oh then what is it?”

Discord giggled, ”have you ever considered how foals don’t have to care about anything? Wouldn't it be nice to be like foals for a day?”

They all looked at each other blushing. Soon Rainbow Dash burst into laughter, “you mean you want to put us in diapers!? No way not in a million years!”

Discord smirked, “come on dashie, if I do I swear no pony would ever know.”

Starlight blushed. “Actually that doesn’t sound too bad I've seen how relaxed Flurry is and I envy being so carefree at times.”

Pinkie Pie bounced in the air with a hoof in the air, “I want to be a foal! I want to be a foal!”

Twilight got up with a smile on her face. “That...actually does sound like fun. I definitely would love to experience not worrying about the fate of Equestria for one day.”

Fluttershy blushed just imagining being in diapers and not saying much. Rarity scoffed,”I will not use my diapers much less just wearing them.”

Applejack blushed “w..well I’m not sure I think it sounds fun. But like Rarity said being diapers isn’t really my style either.”

Discord smirked,”so how about we put it to a vote who wants to try my way of relaxation.”

Pinkie Pie raised a hoof instantly into the air. Twilight blushing raised a hoof as did Starlight Glimmer. The rest of the ponies looked around as Rainbow Dash sighed, “okay I think it’s cle-”

Before she could finish Fluttershy slowly raised a hoof. Discord laughed, “it’s settled.”

Twilight Sparkle blushed, “wait are you going to care for us while we’re like foals?”

Discord smirked, “I have someone in mind.”

Spike stumbled into the room “so this is what you meant about caring for foals?”

Discord smiled, “yes Spike, I think that they have decided to become foals.”

Twilight giggled, “hey Spike, your going to care for us?”

He blushed, “yeah i'm very responsible, and I want to prove it to Discord here.”

The draquenious smirked, “so I guess we can start soon, I mean we can make the castle foal proof and set up only a few rooms to make sure you seven stay out of trouble.”

Rainbow dash shouted, ”wait your going to regress our minds too!”

Discord shrugged, “I feel like that needs to be apart of the package to be sure for you to get the full experience. I mean unless you like messing yourself.”

Rainbow blushed. “Gah, fine whatever.”

The ponies looked at each other with nervous expressions but Twilight came up, “look I know this is going to sound strange but being a foal does sound like a fun way to relax and gather our energy back. Besides Spike is very capable, he’s proven time and time again for being a responsible dragon and I trust him.”

“Wait you’re not going to regress us physically?” PInkie asked, having just noticed that detail missing.

Discord shook his head, “No just your thinking, It would be more fun that way and I can adjust your weight to make you just light as foals to make it easier on Spike.”

“Yeah carrying full grown mares would be hard.” Spike sighed rolling his eyes. ‘Seems a little unfair but alright.”

“Well I have full confidence in you Spike.” Rarity smiled. ‘Such a sweet dragon.” The compliment made the dragon blush.

“Now follow me please lovely ladies.” Discord gestured. “Relaxation awaits!”


Discord had set up four rooms in the east wing of Twilight’s castle, one room was labeled “playroom” the room across from that was “nursery” The room next to that was “feeding room” and the other one was “storage room” He had set up a large pink foal gate barring off from the stairs. The seven ponies stood in the playroom staring at the walls and floor. Pink padding surrounded the walls with an equally giant pink playpen filled with blocks, toys and other assortment of foal things. There was even a pink changing table in the back of the room with the bottom filled with changing supplies, With all the soft plush there would be no way to hurt themselves.

They all were blushing feeling unsure about this as Spike stood next to Discord with a checklist. “Seems like everything is ready to go, now i'm going to start putting you six in diapers and regressing your minds. It’s eleven fifty and at twelve p.m i'll turn into a plushie and will monitor everything just in case if Spike needs help.”

Rainbow Dash was backing up with sweat coming down her face.”No i'm not doing this! I’m not wearing a diaper!”

She was going to fly off when Discord poofed her into a big poofy white diaper inside a wonderbolt style bouncer. She struggled about as she bobbed up and down. “Let me out.”

A glow formed over her head as she struggled the annoyed expression turning into a smile as she began to giggle. She started bouncing up and down faster putting her hooves into the air. She also began drooling with a river of saliva coming out of her mouth and giggled, “I fwyin’ Wheee!”

Discord smirked flicked his claw and a pink pacifier poofed into her mouth as she began suckling it with curiosity at first. Then she began sucking the pacifier contently with a smile as she bobbed up and down. “See what did I tell you? You’ll have plenty of fun.”

” Discord smirked turning to the rest of the mares and cooed. “Oh how about Twilight’s next, she seems the most mature one the bunch.”

Twilight blushed as she asked, “uh c..can I at least still read? I mean at least regress me to where I can still read picture books?”

Discord dawwed, “oh why not but your going to still be in diapers little missy.”

He flicked his claw as Twilight felt the fluffy white diaper starting to strap over her rump. It gently taped itself around her waist with firmly with the leak guards turning into a purple color. Then a blue toddler’s sweater went over her head and was tugged down coming to her waist with the diaper clearly poking out. The purple alicorn blushed seeing how goofy she looked, “oh my this is uh quite foalish.”

Twilight’s mane was then magically tied into a with a little blue scrunchy then the mare felt her mind slowing down memories of knowledge that she accumulated over the years vanished from her mind. Until she could only remember the basic lessons from her years of magic kindergarten and the alicorn sat with a cute poof of foal powder that bellowed from her leg holes.

The filly then grew a big goofy smile. “Hello I twily.”

Discord awwed and pulled a book out from a backpack letting her take it. Twilight giggled lying down on her tummy as she kicked her rear legs making the diaper crinkle as she read in a goofy tone, “it-uh...its...itsy bits...bitsy spidee went up ta wa...wat-watter sp-spout.”

Spike awwed too. “Oh good job Twilight you’re so smart.”

The others remaining seemed a little more relaxed as Rarity stepped forward. “Well, seems harmless enough. Let’s get this started shall we?”

Discord clapped his hands together. “Well let’s see you seem mostly mature.”

“Mostly!” Rarity protest with a huff. “I am a refined mare.”

“And spoiled it seems too,” Discord muttered.

“I am not spoiled! you...you..gah.” She froze for a second as the thick diaper suddenly appeared on her like the other mares. It taped itself around her waist carefully taping around the mare’s rump. Rarity’s mane remained mostly the same other then having a few more curls. She blushed as a frilly pink diaper cover came over the thick white padding and was gently tugged around the mare’s waist. Rarity gasped in horror and squealed, “Hey this is way too embarrassing! I can’t wear this!”

Discord rolled his eyes and flicks his claws again,”oh what’s wrong your going to wear the finest foal clothes in Equestria!”

Then a frilly light pink and yellow dress drifted over her head and was pulled down just inches from her waist making the poofy frilly diaper quite visible. Rarity blushed trying to tug the dress over the diaper, “ugh I’m seriously rethinking this idea!”

The last few garments went over her as a pink cloth went over the mare's horn and pink foal booties dressed over her back hooves. Then poofed on her head a pink frilly bonnet that was neatly tied around her ears. A smile then slowly crept onto her face like the others. “Ooh I so pretty!” Rarity clapped and cheered.

She turned to see a two story dollhouse painted pink. Rarity's eyes glowed with wonder in what she was going to do. She’ll make dolls with the most adorable dresses and diapers then play all sorts of games with the dollhouse. Rarity bounced on her diaper bottom before rushing over to the doll house shaking her rump squealing, “I gonna pway with ta dollies!”

Applejack blushed watching Rarity brushing a doll’s mane, “uh okay guess it’s my turn but don’t make me wear any fufu foal clothes.”

Discord smirked,”okay miss bossy pants.”

Applejack squeaked as the diaper went under her rump rather quickly. With a light flash, the earth pony was also dressed in a little green filly dress. Applejack growled, “Hey! I said no stupid foal clothes.”

She tried tugging on it but her mind slowly regressed . Applejack stopped her tugging and smiled at her dress thinking about how pretty the green looked. The mare began twirling around in it giggling. “Pretty! it’s pretty dressie!”

She then turned her attentions turned to some blocks and she sat down on her diaper with a plop and began stacking them. Then Applejack’s mind somehow drifted to where something was missing from her mouth and she placed a block in and started chewing on the wooden surface. Discord dawwed and poofed a green pacifier in her mouth. “There you go sweetheart no chewing on your blocks.”

Applejack suckled her pacifer contently and her slower mind turned to the colorful blocks and seeing how the pacifier sated her want to suckle. The filly decided to stack the pretty blocks and started building a tower.

PInkie bounced up and down. “Oh me next me, me next!” The energetic pink pony rolled onto the floor spreading her legs.

“I think she wants you to put it on the old fashion way.” Spike remarked watching.

“Well you are the caretaker you do it.” Discord pushed the diaper into Spike’s claws watching the dragon move over.

“I guess you’re right. Easy peasy.” Spike unfolded the diaper trying to slid it under but Pinkie kept swishing about. “H-hey hold still.”

“I can’t help it i’m so hyper.”Pinkie beamed twitching on occasion.

Due to this, the diapering took a while for Spike to get the diaper strapped on the pink mare. He struggled finally taping the tapes onto Pinkie’s waist as he wiped his brow. “Wow uh a little trickier then a normal foal.”

Pinkie giggled some more as her outfit appeared. It was a simple yellow shirt with a blue denim skirt dressed over, with the diaper sticking out quite noticeably. Pinkie Pie's hind legs had matching blue socks with yellow polka-dots and black mary jane shoes slipped over her back hooves. Spike gave the diaper a soft pat as the pink foal rolled over and gave him a hug. The little dragon blushed as he whispered, “You’re welcome, Pinkie.”

Discord smirked as he flciked his claw. "How about a treat for our most energetic foal?"

A oversized foal bottle filled with chocolate milk poofed into Pinkie Pie's hooves. She took the foal bottle with all four legs and fell onto her back revealing her thick poofy diaper. But Pinkie only cared about drinking the sweet chocolate milk, and just began sucking on the amber nipple making loud adorable suckling noises.

Starlight blushed seeing every other pony was now a foal besides Fluttershy. Discord turned to her and asked,”so are you ready?”

The light purple coated mare nodded, ”yeah c..can you do me a favor Discord?”

He turned and eyed Starlight as he asked,”maybe what is it?”

Starlight blushed as she whispered, “can I be the youngest? I mean...regress my mind to that of a one year old...I really want to be as carefree as possible.”

Discord bowed,”it will be my pleasure.”

He flicked his claw as her mane was styled into two big pigtails, a cute blue green t-shirt was then slipped over her head, and a diaper was neratly taped around her rump. Starlight’s mind regressed with her mind almost going completely blank leaving nothing but foalish instincts. As she began drooling and plopped onto her rump. She stared up at Discord with a spaced out look and babbled gibberish making Spike giggle, “oh wow you really are regressed.”

Starlight just looked down at her back hooves and she fell onto her back attempting to put the apendages into her mouth. Each time she raised her legs ended in failure with her legs falling back onto the ground with foal powder poofing from the leg holes. She was finally able to pull it off however, as her right back hoof went into her mouth. The foalifed Starlight began suckling it without a care in the world.

Discord laughed, “so adorable.”

Fluttershy blushed, “well it looks like i’m the last one.”

Discord smiled, “so how young do you want to be?”

Fluttershy turned to Starlight suckling her back hoof without a care and whispered, “ca..can I be like Starlight?”

Discord dawwed, “of course, and i’ll even be your plushie.”

He laid Fluttershy down and took out a diaper and a some foal powder. “Alright now, hold still.”

He proceeded to powder Fluttershy’s rump soon pulling her tail through the tailhole and taping the mare up over her waist.

Fluttershy gave Discord a sweet smile as she adjusted her hooves making the large bulk crinkle around her rump. “Thanks Discord that was nice.”

He smiled at the padded Fluttershy, “it was my pleasure.” He then took out a brown colored bunny onesie and cooed, “raise your hooves to the sky”

Fluttershy giggled as she did so and Discord placed the onesie over her before laying the mare back down and buttoning up the snaps around the hatch. Fluttershy’s mind was now regressing as she just sat in her foalish outfit with a spaced out look. She gazed up at Discord and lifted her forehooves as if wanting to be picked up. He smiled at that and slid a blue green pacifier into Fluttershy’s mouth, the foal gave it a few curious suckles.

“Your so precious.” Discord booped her nose before turning to Spike. “Okay Spikey you’re on your own from here on out. Remember our bet you have to care for all seven with no help."

Spike smirked as he crossed his claws “You just watch me your going to be paying up by tomorrow.”

Discord laughed, “we’ll just have to wait and see!”

He then flicked his claws and in a puff of smoke Discord was now a plush doll in the hooves of Fluttershy suckling her pacifer and lifting him in the air. The foal cooed and gave her new toy a hug loving how soft it felt against her fur.

“Seven foals, yeah I can handle this..I hope.” Spike looked over the room almost second guessing his own plan. “I mean, how hard can it be?”
