“Right, let's do another one!” Gilda demanded, struggling a little to set her side of the board up again. “I'm definitely going to win this one!”

Trixie's face set into a competitive grin, and she began doing the set up as well.

As the two of them got more into the game they were playing, the game of Mousetrap continued as Starlight picked up the dice with some difficulty.

She rolled it, producing several mousy squeak noises, and the plush cube rolled to a stop on the number five.

Thickly padded mouse sleeper wiggling from side to side as she advanced, Starlight went past the similarly mouse-clad Ember to land on a new square.

“Aww, not fair!” Ember complained, as she saw the square Starlight was about to land on. “You're getting more cheese than me!”

Starlight picked up the cheese piece, and hesitated – but the allure of the incredible taste was too much, and she ate it quickly.

Every bite made her mouse costume get thicker and plumper, her diaper expanding beneath it, and when she finished Starlight groaned in pleasure.

As she sat down on her diapered rump, the other part of the square activated – adding another piece to the growing contraption in the middle of the board.

“Well,” she said, belatedly responding to Ember's whine. “You – you should be in front, then!”

“I will!” Ember declared, picking up the dice and rolling it. That only produced a two, though, and she pouted before waddling forwards two spaces and sitting down.

“Not fair,” she repeated, finding it hard to express herself more eloquently as she licked her lips and thought about having another slice of cheese. “You're going to get to the big cheese plate first...”

As Starlight struggled with the Dice once again, Discord was busy assembling the next part of the machine. He took a step back, rubbing his somehow oily hands with a rag as he admired his handiwork. The oversized plastic crank now tied to an enormous set of stairs where a large ball of rubber sat at the top. Starlight rolled a one, marching forward and requiring another piece to be added to the machine. As the two approached the end, the machine steadily grew larger and more complicated, Discord panting from the effort of lifting the pieces.

While their game continued, Shining was struggling to think of more words to put down on the board. He moved the letters around on his stand, scratching his head. ‘CARROST’. What kind of letters were these? He couldn’t make anything with them! Grumbling, he found a small spot that had yet to be taken and simply changed Cadence’s ‘Puff’ to ‘Puffs’ and ended his turn.

Cadence was having similar difficulty with her letters. No matter what she tried, she couldn’t seem to think of something? ‘Balloon’?, No she didn’t have a B. ‘Swell’? No. ‘Wet’? She pondered it. She did have the letters, but where would she put them? She scrunched her muzzle, rocking back on her diaper and hearing it crinkle softly as she struggled to think of more words.

Eventually, the pink Princess admitted defeat – putting two of her tiles back in the bag, shaking it around, and taking two out again. With only one other tile in the bag, she got the same ones again, and pouted in annoyance.

For her part, Twilight had to look long and hard at her letters – trying to see if there was any pattern to them at all. There didn't seem to be anywhere on the board where she could make a word, and while a few suggestions floated through her mind – 'adult', or 'smart' – she dismissed them as nonsense words almost automatically.

Finally, she saw something! Carefully taking her letters, she laid down 'infantile', then sat back on her diaper with an audible squish.

Shining moved quickly, putting an R on the end of Twilight's word, making 'infantiler', and Cadence followed that up by making it 'infantilerer' and getting a triple word score.

“Aha!” Daybreaker laughed, pointing. “Your Shadowbolt is doomed! Attack!”

A pony in a Wonderbolt-like costume and a thick diaper inhaled, then puffed his own costume up to enormous size. Bouncing into the air, he landed on Nightmare's only remaining Shadowbolt and flattened them beneath his padded posterior.

“What do you think of that?” Daybreaker demanded, looking up at Nightmare – only to see her sister and foe smirk.

Another Night Guard advanced the final space, reaching the other side of the board, and their diaper glowed – then expanded rapidly, engulfing the Night Guard and turning them into yet another Nightmare Moon. A Queen piece, to go with the other Queen pieces Nightmare Moon had already promoted.

Daybreak gulped, looking over her other shoulder to see the second Nightmare grinning widely as she waddled up to smack the Wonderbolt off the board with her enormous tush. Daybreak tried to spot a way out of her predicament, but everywhere she looked was a fat, thickly padded Nightmare or one of her subjects. In a desperate attempt to stop her sister’s advances, Daybreak’s horn lit up to slide one of the rubbery bounce-house castles to block Nightmare’s advances. In response, an overstuffed plushie Diamond Dog bounced over to land on top of the castle. The seams strained as it creaked before bursting below the Diamond Dog, leaving it sitting smugly on its gut.

Finding herself surrounded, Daybreak attempted to dash in one direction, only to rebound off the large rump of Nightmare. She shook her head, attempting to regain her senses, but before she could all three Nightmares were standing around her. “Checkmate~” They all said before pouncing upon Daybreak, squishing and squashing her with their crinkly rears.

“Uuuuuuuggh, again?” Gilda complained. Trixie had won three times in a row, and had only managed to be suited up in a rather thin Sweetie Belle costume while Gilda was sporting several overly puffy suits. “You’re cheating, there’s no way you can win this much!” She grumbled as a thick Zecora suit plumped up around her. Trixie simply hummed happily as she set up yet another game.

“Trixie never cheats! Except when playing fair doesn’t work.” She pulled her character card out as Gilda did the same, her movements restricted by the thickness of the suits.

“All right, then,” Gilda muttered, replacing her card, and concentrated.

“Does your character… have wings?”

Trixie shook her head, and Gilda knocked over the wing-bearing pieces. Then it was Trixie's turn to ask a question, and Gilda confirmed that – yes, her own choice had a mane.

Piece after piece went down as they rattled off the questions, and Gilda squirmed a bit – feeling like she really needed to use her diaper, the urge growing stronger with every moment.

Finally, she was down to just three cards left, and knew Trixie had to be one of them.

Shifting in her seat, trying to cross her hind legs even through the three thick plush suits she was wearing on top of the thickness of her diaper, Gilda frowned. “Does your character… have a horn?”

“Nope!” Trixie said proudly, and watched as Gilda reached out to one of the remaining pieces… then flipped all three down, one at a time.

“What was that you said about cheating?” Gilda demanded.

“Um, that is...” Trixie began, nervously, then shook her head. “You must have made a mistake-”

“So who is your character, then?” Gilda went on.

“Rainbow Dash,” Trixie announced.

“Rainbow Dash has wings,” the costumed griffin pointed out.

“Well, of course Trixie meant the unicorn Rarity,” Trixie said instead, not noticing the tingling sensation around her back.

“She's got a horn, and you said they didn't have a horn.”

“That's because Trixie misspoke. She meant that her character was a baby dragon-”

“-who have scales, don't they?” Gilda replied, starting to smirk. Unlike Trixie, she could see what was happening, and she liked the result. “Come on, who was it?”

“Well, um...” Trixie looked from side to side, not noticing the thick, plushy sleeper growing over her. Every time Gilda pointed something out, the sleeper changed, picking up the features or details in question and getting thicker still.

Trixie’s suit grew thicker and thicker, slowly spreading her legs as stripes grew along them, and a thick draconic tail sprouted from the puffily padded rump. “I… well… er…” Trixie continued, gulping as the belly of her suit swelled out along with the rear. Gilda simply giggled, rocking back on her own rear as she tried to bite back laughing at Trixie’s silly form. Squeezing her legs together, she snickered further, until a faint ‘hiss’ joined in her laughter. Her own padding began to swell slowly as Gilda wet it, Trixie still attempting to bluff her way fruitlessly.

Starlight and Ember were now neck and neck in the game, both standing at the big pile of cheese at the end of the map. Each was stuffing their suit pockets full of slices, occasionally chomping down on them as their suits grew bigger and bigger. Neither was paying much attention as Starlight planted her puffy butt down, causing the final piece of the trap to be put into place. Discord began to turn the crank, causing the rubber ball to roll down the ramp, which bounced off of a puffy plaid mattress to land in a basket, that began working an air pump to blow up a balloon, which tipped up a plank to send a wrecking ball swinging and knocking a marble onto a track… which promptly got stuck. Discord grumbled, walking over to the track and giving it a swift kick. “Stupid thing, never works right…” The marble was dislodged, rolling faster and faster until it hit a crib-like cage.

The cage fell down, the rattling causing both Starlight and Ember to look upwards. Before either could react, though, they were suddenly squished tightly into each other’s puffy butts as the cage landed on top of them. Muffled cries for help could be heard as they pushed against each other, their suits squeaking as they wriggled their puffy trapped rears.

“Wasn't that fun?” Discord asked, picking up the cage with one hand. For some reason it stayed sealed at the bottom, keeping the mouse-costumed pony and dragon inside, and he put it under his arm and walked off with a whistle.

As he did, the miniature world of the Mousetrap game vanished in a puff of cheese, leaving them back in the play area with the other 'pupils' who'd just finished their games.

“Didn't everyone enjoy that?” he asked, ignoring the simmering glare from Day Breaker. “Play is important for Princesses as it keeps them properly proud! And other things that begin with p.”

Placing the cage back on the ground, he lifted it so that both Starlight and Ember could get out, though with their squeaky, padded costumes they weren't going anywhere fast.

“But now it's time for more fun!” he announced. “Everyone knows educational videos are common for school students… but that's boring, so we'll just watch a nice movie instead!”

“Wait, hold on,” Gilda said, frowning and trying to think. “That game wasn't fun… hey!”

A neat ribbon wrapped around her beak, tying it shut with a pacifier in it for her to suck on. “Don't speak out of turn,” Discord chided her. “Now, take your seats!”

Not looking to see if any of them were doing as he'd told them, he teleported to the front of the class and pulled on a window cord on the side of the blackboard. It wound up like a blind, revealing a giant television screen, and it showed a snowy static image for a few seconds before pausing just as it cleared up.

“Nightmare,” Discord said. “Either stop sitting on your sister or move so she can see the screen.”

Nightmare obliged, turning around so that Daybreak was now facing the screen, but continuing to lean backwards into her sister’s puffy rump to use as a backrest for her new sister seat. Daybreak grumbled, wriggling about under the fat alicorn. Even occasional grunts of embarrassment and attempts to free herself could be heard from Celestia as she tried to push Nightmare off her.

Discord started the movie back up again before wandering out of view of the projector. The screen flickered back into motion, showing the title card of some old cartoon. Twilight stared up at the screen, rocking slowly forward and back on her diaper. The screen showed some filly waddling along the street, thickly padded and several books tucked under her wings. She bobbed her head to the music, a bow in her mane and tail bouncing as she did. As she waddled along, she noticed an unattended balloon stand, marveling at the globes of rubber floating above her.

As the movie continued, Trixie’s attention was momentarily pulled away as Discord walked up beside her seat, several bags of popcorn and oversized bottles of soda in his arms. He began to pass them out, each pony beginning to munch and suck on the bottles as they watched the film.

The filly was now attempting to climb up the stand towards the balloons, her padding wiggling precariously closely to the tank with which the attendee filled the balloons.

For a moment, as Ember stared at the screen, she thought she saw something else on it at the same time. Something-

She blinked, and lost it, and within a moment it didn't seem important at all, so she subsided and continued to suck on her bottle.

The filly on the screen got a hoof over the edge of the stand, and pulled hard – lifting her most of the way onto the stand top. Then she slipped back again, and got her diapered rump stuck squarely into the nozzle of the helium tank.

It hissed automatically, and began to make her padding puff up and inflate. The sounds were oddly pleasing, squeaks and creaks and crinkles, and they made more than one of those watching smile faintly – something about them just feeling right, as if they wanted to make that kind of sound themselves.

Ember blinked again, catching a glimpse of something else on the screen. It was like a spiral, and there were words on it… but as she tried to read them, she relaxed, and the spiral vanished again.

By that point the diaper had become large enough to start to make the pony bob about in the air, too, and then her surprised flailing knocked the tank valves so the helium rate increased.

As the filly’s diaper ballooned, lifting her rear up into the air, Starlight squeezed her own enormous padding between her legs. She thought about how fun it would be for her own diaper to swell that large… it certainly had gotten quite big already. She smiled, imagining it swelling like the one the filly was wearing. She squeezed her diaper again, sighing as it crinkled softly.

Daybreak and Nightmare were munching away on their snacks, Daybreak attempted to swell enough to push Nightmare off her, and Nightmare attempting to pack on enough pounds of fluff to keep Daybreak pinned.

Cadence watched as the filly began to float along through the sky over the town towards her school. She blinked, suckling on her bottle as she watched. She leaned over, flopping against Shining as she wiggled her own padded rear. Shining looked over as Cadence fell against her, and thought he saw… something glittering in her eyes. As he blinked, it seemed to go away, and he was just left with this warm fuzzy feeling inside. He leaned into her as well, both eating their snacks as the movie showed the pony attempting to deflate her diaper to land back down at her school.

Gilda clicked her beak as she sucked on her bottle, eyes drooping a little as she kept watching.

It was kind of funny, actually… normally, she thought TV like this was just for total dweebs, but this time it was kind of interesting. Even that there was a pony in it didn't stop her being interested, and she stared at the screen.

Her eyes shimmered a little as the programme taught her things. Things which a casual observer would think weren't on screen at all, but she learned them all the same.

As she watched, the pony drifted slowly down from the sky. Her diaper didn't deflate all at once, producing a series of melodious paa-arp sounds like a particularly silly trumpet, until finally she reached the ground just outside her school.

Going inside, she was met by a teacher, and the teacher asked her if her diaper was comfortable.

“Yes,” Gilda answered, barely hearing the rest of them all saying the same thing, and wiggled in her soft, comfy diaper.

The filly trotted to her seat as the teacher looked down at a list of ponies. Most had appeared, but one was still missing! The scene zoomed away to show a pony curled up in bed, squeezing a small bird plushie in his hooves as he buried his face in the pillows. Crinkles could be heard as he wiggled his rear happily under the covers, sighing contentedly.

Trixie sighed, wishing she was able to curl up in her bed with her own plushies. She closed her eyes, imagining herself laying in a big crib just like the colt was. As she did, she felt some thick blankets falling around her, letting her wrap them up around her to keep her warm. If being a prissy padded princess meant she could be this warm and cozy, she thought it certainly would be something she could get used to.

The colt rolled over in bed, kicking his legs as a soft hiss could be heard as he wet his padding, letting out a soft sigh. As if on cue, several more hisses could be heard as the class wet their padding as well, enjoying how warm and soft their padding was.

Twilight yawned, feeling tired just from the suggestion of somepony snoozing in diapers, and snuggled down into her own sleeper a bit more. It made her feel cozy, and safe, and a little bit more of the messages in the film slipped through into her mind as she watched.

The view on the screen swished and dissolved as it went from showing a pony asleep to showing that same pony, galloping along with a falcon on his back and a determined expression on his face.

Oddly enough, it was as if there were two pictures at once – the one showing the cool-looking stallion and his fierce companion falcon, and another one showing a little colt waddling along in his diaper with his plush in one hoof.

The lesson was obvious, and Twilight nodded absently – absorbing the lesson that foals had a vivid imagination, and it was more fun to do things like that. That playing was absorbing, and could feel very real.

The colt was waddling as fast as he could, a determined look on his face as he imagined great beasts popping up out of the ground before him. His adult form slashed at the beasts with a sword, the colt prodding an oversized pooltoy with his own foam sword at the same time. The pooltoy bounced backwards, the beast recoiling and crying out a rather squeaky yell of pain.

Shining leaned forward, thoroughly invested in the colt’s playtime. He wasn’t the only one, as Ember watched with wide eyes as well, though she was rooting for the other team. The toy and creature swatted at the colt, who dodged to the side, only barely avoiding tripping from how widely his thick padding was spreading his hind legs. He threw his plushie at the beast, imagining his falcon flying high to scratch and claw as the monster. The toy leaned backwards before flopping forwards, and the colt leapt upon it.

Several squeaks and creaks followed as the colt attempted to defeat the monster, but his struggling only ended with him pinned under the toy, his imagination creating a laughing plump rubbery creature smushing him under its oversized behind. He grumbled, pushing against the toy as he tried to free himself.

No matter how hard he tried, the colt couldn't manage to get himself out from under the pooltoy, and his movements made it squeak ominously. His imagination turned that into the rubbery monster laughing louder, squeaking with every breath, and inhaling much more than it was exhaling – growing larger and larger, squashing him down and rendering him helpless.

The whole scene was especially potent for Celestia and Luna, stuck inside their Daybreaker and Nightmare plush suits which almost recreated the scene. The images made them feel more and more deeply involved in the show, as the shifting of the toy turned into the rubber critter squishing up and down on top of its victim.

Copying the critter, Luna/Nightmare lifted slightly off Celestia/Daybreaker before sitting right back down again and wiggling her tush – teasing her fellow prissy pampered princess, just like she was supposed to.

Eventually, however, the colt freed himself, and the dream transition flickered again. This time it showed the colt in bed, stirring to look out the window, and the camera viewpoint followed his gaze.

The sky was dark, the moon hidden behind a cover of thick clouds, which only dimmed the night even further. The colt gulped as he looked out through the window, thinking he saw something moving around in the distance. Despite nothing seeming to be outside, the colt, and subsequently, Twilight were both quite scared. Incoherent shapes moved outside, and the colt let out a yelp before ducking down under the covers, quaking. Twilight gulped as well, sympathizing with the young pony. The outside was scary, and her bedroom, diapers, and plushies made her safer.

Twilight squeezed a small Spike plushie, suckling on her pacifier as the foal squeezed his own toy to keep him safe from the monsters hiding outside. Even his padding seemed a bit thicker than before, making him feel even safer. The camera began to sweep out over the landscape, moving over to another filly’s room, where she was out stargazing, pointing out shapes in the skies above.

The constellations formed one by one as the filly pointed to them, showing Ursa Minor then Scorpius then Vulpeca, before moving on to show Ursa Major and Cygnus and all the other constellations overhead.

All the stars overhead twinkled, shimmered, or glimmered and wavered in the deep black sky, and a nebula swirled in the night. It was all very peaceful, and the watching diapered-up students began to have stars in their own eyes as well.

Every glitter seemed to take away a little more maturity, replacing it with foalish wonder at the beauty of the night. Every pattern of stars became an animal, or a beast, and Cadence saw one pattern of stars which looked just like a heart.

She giggled when she saw it, before remembering to be quiet.

At the bottom of the view, the filly continued to watch the stars and point them out. Her diaper was already damp, showing how long she'd been doing it, but she didn't seem to notice – and as she continued to watch, she shifted a little without noticing before starting to soak her diaper.

As the filly wet her diaper again, the stars above seemed to shift and swirl, their twinkling drawing in everypony watching even further. The stars formed more creatures, each large and plush, with thick diaper wrapped around their haunches. The constellations began to prance about the sky, waving their overstuffed pampers around as they did. A kangaroo bounced along on its swollen diaper, while a bear was chasing several large honeybees with an outstretched diaper. The plush bees swarmed in, making his padding bloat up just a bit as they buzzed, rumbled, and quivered in his diaper as the bear waddled around.

Shining giggled at the sight, the idea of the bear possibly being stung never crossing his mind. Instead, all he could think about was how silly all the animals looked, and how happy they all were dancing and parading around their thickly padded rears. He wiggled in his own padding, imagining showing off his diaper to everypony. They’d just love having a diaper as thick and puffy as his, he was sure of it!

The movie continued, yet steadily each scene lost more and more coherence until it was soon nothing but a swirl of colors and shapes, with the occasional thought of thick diapers, wet diapers, big diapers, and all kind of diapers flowing through everypony’s head as they watched.

Back in Twilight's room, Spike found himself captivated by the holo-foil effect of the page showing the film being watched. He had to keep staring, unable to pull his eyes away any more than the students watching it in the classroom, and he found himself not really able to come up with a reason why he should pull his eyes away either.

The captions told him that everyone who watched the film found themselves entranced, and Spike nodded as he absorbed that instruction.

Discord spent the time doing a crossword, filling in clues and doodling in the margins. The crossword was done on the surface of a sphere, but that didn't seem to present him any problem – though he did end up covering the entire sphere in closely spaced letters by the time he was done.

Checking his watch – a sundial with an attached lamp – he clapped his hands sharply. The movie ran through the last ten minutes in about three seconds, fast forwarding with an audible zip-zip-zip, and finally concluded.

“Now, wasn't that nice?” he asked, as the Princess Pupils began to realize the screen had stopped giving them instructions. “I thought so! And since you were all such good watchers, it's time for dressup!”

Waving his hand, Discord made one entire wall of the classroom rotate one hundred and eighty degrees to reveal a collection of wardrobes, drawers and racks of clothing.

“Now, as you all know, common sense means you can only wear one outfit at once,” he lectured. “But you're Princesses, so that doesn't apply! Go ahead and wear just as much as you want!”

It took a moment for everypony to regain their senses once the movie had finished. Nightmare was still bouncing lightly on top of Daybreak, both guzzling up their drinks to swell even larger. Eventually Cadence’s eyes adjusted back to the bright light of the classroom and noticed the ridiculous number of dresses hanging on the wall. Waddling over to them, she pulled a pink, frilly dress from off of the rack, slipping it on over her. She grinned at how the dress held her snugly, the skirt framing her thick padding cutely. Shining was following closely behind her, pulling out an outfit that looked like a royal guard’s uniform, had it been crafted for a young foal to wear on Halloween. The buckles were far larger than anypony would need them to be, and short chains running between the buttons jangled loudly as Shining attempted to slip in.

Meanwhile Starlight was busy stuffing herself into a sleeper not-unlike a spacesuit. The material creaked as it strained to stretch around her large diaper, Starlight blushing and grunting from the effort as she slid down into it. A flap on the back of the suit bulged outwards as her diaper pushed up against the inside. The front squished down into the floor from the bulk of her padding, and Starlight’s hooves were lifted so high she could only reach the floor by squeezing her hind legs into her diaper as well. It wasn’t too long before she had managed to slip it on, the buttons on the flap straining to hold in her overstuffed padding as she bounced into the air.

To her surprise, however, she bounded much higher than she would have expected, her head bumping into the ceiling before she came flopping down on her pampered behind. As if she were really on the moon, any soft step sent her sailing through the air!

Starlight laughed with joy at the sensations, a peal of enjoyment which made Trixie look up from what she was considering.

Turning her attention back to the costumes, Trixie held up first one and then the other. There was a costume worthy of an archmage, with starry swirls and coils of flame and smoke decorating the robe, and there was an entirely different outfit to make the wearer look like a classy, aloof cat.

After several more seconds of thinking, Trixie decided there was no reason she couldn't have both of them.

Unzipping the cat costume, she fiddled around with it to make sure she could fit inside and then stepped in. Her hooves slid down to the ends of the sleeves for all four legs, reaching snug little compartments which cushioned them with plush paws, and she used her magic to pull hard on the zipper and get it back up to the neck.

By the time she was done, only her face stuck out of the feline outfit – which now seemed to be a lot more puffy than it had been when she was considering it. The bulk of the outfit only magnified the puff of her diaper, and the paws made it so every step was even more of a waddle than it had been when she was just coping with a thick diaper.

Undeterred, she draped the archmage costume around herself as well. The springy tail of the cat-costume meant she couldn't get the robe to drape down and conceal her feline diaper-butt, but she still liked the look – especially with the very impressive hat that came with the mage outfit.

Nightmare glanced over to watch the others, only to spot something hanging on the rack. Something she thought would just look perfect on Daybreak. She jumped to her hooves, Daybreak taking a gasp of air at the weight finally removing itself from her. She glared over at Nightmare, only to see what she had in her hooves. In stark contrast to much of the other outfits on display, the jacket Nightmare held was rather drab, a simple faded blue color, but what worried Daybreak was the number of straps and buckles along its overly-long sleeves. Daybreak got to her hooves as well, only to have Nightmare begin to chase her. The black alicorn leapt forwards, tackling Daybreak and causing the two to roll over each other.

Despite her struggles, Nightmare soon found herself attempting to tug the straitjacket away from Daybreak, both ponies holding tightly to one sleeve. “Nnngggh, quit struggling, Daybreak, you’ll surely be the talk of the town in this!” Nightmare cried out.

“Ha! As if I’d even take your fashion advice on something that wasn’t meant to trap me!” Daybreak replied, pulling again on the jacket.

“Girls, girls! There’s no need to argue, I’m sure you two can share!” Discord suddenly puffed up between the two, his arms outstretched to press against both of their rears. The ponies paused, looking confused, only for a second later Discord to shove on their rumps and push them together. With a pomf, the sisters were squeezed tightly together, the jacket wrapping itself around both of them until they were stuck, side by side, diapers pressing snugly into each other with their hooves bound tightly across their chest. The sisters squirmed, crinkles filling the room as they tried to free themselves. Inside the alicorns, Celestia and Luna blushed brightly as they felt themselves squeezed and confined even further by the jacket hugging their sentient suits.

As the two struggled, Twilight was considering her options at the other end of the room.

This end seemed to be devoted largely to costume outfits that were like sleepers – complete from horn to hoof, and swaddling up the pony who wore them so they looked like somepony or something else entirely. The rack she was looking at contained costumes as diverse as a fox, a hawk, a sea urchin and what looked like an accountant.

As she pushed through them, however, one of them moved more than she could explain from just how she'd been trying to move it aside.

She examined it, confused, then tried again – only for it to suddenly animate, leaping off the hanger and going after her.

“Help!” she yelped, falling over backwards in a cascade of crinkling from her diaper and the alicorn sleeper she was already wearing, and Discord appeared next to her.

“Oh, Twilight, how wonderful!” he said, clapping. “You found one of the special self-applying sleepers!”

Twilight tried to kick out at the yellow sleeper as it wrapped around her legs. “Get it off me!”

“Sorry, no can do,” Discord replied, holding up a ten-page section of small print. “By activating it you've chosen to wear it, and you'll have to take it off yourself.”

By the time he'd finished, Twilight was already mostly stuck in her new sleeper, and it finished zipping itself up as she struggled back upright. It was mostly yellow, with a white underbelly, 'paws', eartips and tailtips, and looked mostly like a fox except for the odd white-and-black markings on the flanks.

“What even is this...” Twilight asked, trying to reach the zipper only to find it appeared to have vanished entirely.

“Well, I'd love to tell you, but Bandai would probably sue,” Discord said. “I hope you enjoy your Renasleeper!”

“Rena-what?” Twilight asked, then she slipped as her sleeper's silky paws failed to give her traction. She fell rump-down onto the floor, producing a squish sound, and put her head in her puffed-up paws.

Grumbling, Twilight tried to get back to her hooves, but no matter how slowly she moved and how careful she was to keep her balance, the paws of the suit were far too slippery. She flopped down on her rump once again, Starlight bouncing over her and giggling happily as she wiggled her rump about. Forced to crawl along, Twilight moved away from the animated sleepers in hopes of finding something a little more modest.

Gilda and Ember were both still searching, Gilda pushing aside the still damp raincloud outfit that she had been forced to wear earlier. She soon spotted an oddly thin sleeper, one that was a jet black, save for a blue back and two insectoid wings. Stretching the rubber, Gilda slipped herself into the material, which folded neatly around her talons to allow some amount of dexterity with them. She looked over to see Ember flopping down on her diaper, wrapping a bib around her neck with a few booties slipped over her feet as well. Despite the absurdity, Gilda was a bit jealous as Ember’s look, wishing she had spotted the booties first.

With flash of light, Gilda suddenly felt her suit plump up, shifting colors to resemble the dragon in front of her, until she and Ember were indistinguishable. At least, they would be if Gilda’s head wasn’t perched atop the fat dragon. “Eeep, what the heck?!” Gilda cried out.

Discord appeared beside her, as if on cue. “Gilda, you’ve forgotten the hood! Nopony will be fooled without that!” He suddenly revealed a changeling hood, slipping it over the gryphon’s head. With another flash of light, Gilda’s head now resembled the dragon, if only for a moment before another flash left Gilda now wearing a rather plump Discord imitation.

“This is just ridiculous,” Gilda muttered, pushing the hood back, and looking around to see if anyone else – largely any pony else – had noticed the embarrassing outfit she was wearing.

Looking between the straitjacketed rulers of Equestria, the posing rulers of the Crystal Empire, Twilight's odd fox-like sleeper and whatever Trixie was trying to pull off, she realized she might just have gotten off lightly – though, speaking of lightly, Starlight was still jumping around.

“I think there's altogether too many grumpy Princesses in this room!” Discord said. “Remember, good princesses love to dress up!”

The words echoed in Gilda's mind for a moment, making her feel a bit odd, and then she frowned.

Had she felt annoyed about something? Why would she be doing that, when she had the best costume of all – the costume that could let her have whatever anyone else picked whenever she felt like it!

Feeling much more happy about her choice, she put the hood back up again and went over to play a prank on Cadence and Shining, her outfit shifting as she wondered which of the two to imitate.

The two in question were busy debating over what the theme for their next costuming should be, prissy, or pampered?

“Prissy, obviously! The frillier, pinker, and cuter, the better princesses we are!” Shining declared, holding up an almost painfully bright pink tutu.

“Shiny, dear, pampered is what we need! Why, with the thickest diapers, we’ll be unable to be ignored!” She held up a onesie with a built in padded behind, one almost as large as Starlight’s.

“Oh, I suppose you’re right, pampered it is.” Replied the second Shining. Shining and Cadence looked over, to see another Shining, in the same outfit, sitting beside them.

“What the? Who’re you?” Cadence asked, dropping her outfit.

“Cadence, how could you! You know your dear tubby wubby hubby!” Shining replied, looking hurt.

“What? No, I’m her tubby wubby hubby!” Shining interjected, crossing his hooves and pouting.

“Well, I don’t see how that’s true! You’re aren’t looking too tubby to me!” Shining answered, poking at Shining’s belly.

Shining blushed. “I may not be tubby, but I am just as wubby!”

“Prove it.” Shining stuck his tongue out.

Shining glared at Shining, moving over to the rack of clothes and pulling out as much frilly, prissy, padded, pink, princess pampers and costumes he could. He slipped the tutu on, Shining yawning as he did. “Oh, so you’re a little wubby. I’m still tubby.” Shining grinned. Indeed, the waistband of his diaper had stretched a bit, and the buttons on his jacket were straining to hold in his swollen gut.

Shining gasped, only to slip on another silly overstuffed bonnet. “Stiiill not enough!” Shining proclaimed, his gut now poking out from under his jacket. Shining added more clothes, while Shining continued to balloon out, chuckling as Shining embarrassed himself.

Eventually, after more than three minutes, Shining and Shining were both shaped almost like beachballs from the sheer volume of costume they were wearing.

“Well?” Shining asked, panting. “Is that tubby-wubby enough?”

Cadence giggled. “I think much more tubby might be too much for the room!”

“Yes!” Cadence agreed. “Just as cushy a captain as can be!”

Cadence and Shining both looked at Cadence, neither noticing that the other Shining had vanished. “Where did you come from?” Shining demanded.

“Don't you remember?” Cadence asked. “We met years ago!”

“But that was me!” Cadence said crossly. “This is my tubby-wubby-hubby, go find your own!”

Cadence looked Cadence up and down. “You're Cadence, are you?”

“Yes!” Cadence agreed firmly.

“Well, you don't look nearly royal enough to be Cadence,” Cadence challenged. “So therefore it must be me. Simple!”

“I do too look royal!” Cadence gasped. “You take that back!”

“Don't look very royal to me,” Cadence replied. “You're not nearly frilly or sissy enough!”

Cadence snatched up the bright pink tutu Shining had been holding, and put herself in it. “There! See?”

She looked at Cadence, and her jaw dropped. Cadence was just as frilled-up as Cadence was, and struck a pose.

“See?” Cadence said. “You don't have the glam to be the real Cadence.”

Cadence turned, her tutu's miniskirt flaring up as she rummaged through the nearby outfits, and began throwing on frilly outfit after prissy, pink, sissy outfit – trying to outrun whatever Cadence was doing to match her.

Starlight bounced by again, her rump squeaking and crinkling as she rebounded off the floor with it, tumbling through the air. She waggled her rear, the buttons still straining to hold in her massive diaper. As she fell from her arc once again, she landed on top of Ember, who was searching around for a bow for her tail. With a few pops, the buttons on Starlight’s spacesuit flew open, exposing her thick diaper. The unicorn blushed, wiggling her rear as Ember tried to pull herself out from under her. Discord walked up, helping to tug Ember out and giving her a pat on her rear. “Oh, Ember, if you wanted to snuggled up to Starlight, all you had to do was ask! I’m sure she’d love to have you squished under her rear!”

Ember shook her head, but Discord simply dropped the dragon into the sleeper before pulling the flap back up and securing the buttons. “There you are!” He bounced his rear into Starlight’s, sending her flying back through the air again as Ember struggled to free herself from between the cozy sleeper and Starlight’s puffy, plastic pampers.

Meanwhile, Trixie was examining herself in the mirror – from hat to tail, her outfit looked just right!

Still, though, as she swung her rump out to the side, she couldn't help but think something was missing…

Thinking about the look, and about her kittysuit and the puffy paws it included, she suddenly realized – of course! She wasn't dressed as a magic user herself, she was dressed as a witch's familiar!

But that meant she needed a witch to be the familiar of – at least, that seemed to make sense. So she looked around, at the ponies and non-ponies who were already paired off in their costumes.

The two rulers – Nightmare and Daybreak, or Luna and Celestia – weren't an option, because they clearly went together. And Ember and Starlight were clearly having fun as a pair, and so were Shining and Cadence and Cadence.

Trixie's mind skipped a beat at that one, but she shrugged it off and moved on to the final Princess – Twilight, who was dressed in a cute, puffy fox-like costume but who wasn't wearing anything on top.

Trixie nodded to herself. Of course – Twilight was dressed like an animal, and so was Trixie. It made sense that one of them would be the familiar of the other.

Which was the familiar of which, though, was something she would have to think about. Once she'd persuaded Twilight to dress in something similar.

Mind made up, she gathered up a collection of costume bits a lot like the ones she was wearing – all kinds of things related to magic – and headed over to Twilight.

Twilight was attempting to free herself from her costume, her hooves running along the body in search of any form of zipper or buttons to open. She flopped onto her back, grumbling, only to notice Trixie leaning over her, grinning. “Uh… Trixie? What’re you doing?”

“Why, Sparkle, I would think that was obvious! Being a magical feline familiar, I need a familiar to be familiar to too! And you are the pony Trixie is most familiar with.” Trixie stated matter-of-factly. Twilight just looked confused, but Trixie waved her hoof dismissively as she lifted Twilight to her hooves again. “Oh, it really isn’t that complicated, all it means is that you get to be the witch! Once you’re more familiar to me, that is.” She said, holding up the witch’s outfit. The cloak looked more like a Halloween style quilt, very thick and very warm. The hat wasn’t much better, seeming just as heavy as the cloak was. Twilight’s eyes widened and she shook her head, stepping back.

“Uh-uh, no way! I’ve got enough fluff on me already!” Twilight proclaimed, indicating the thick suit.

“Remember, there’s no such thing as too much fluff!” Discord shouted over the others, snickering.

Twilight’s head grew a bit cloudy. Why was she so afraid of getting more fluff? After all, fluff did mean being comfortable, and more fluff would mean more comfort, wouldn’t it? As she thought, she barely registered her hooves reaching out to take the costume from Trixie and begin to wrap it around her.

Trixie beamed as she watched Twilight slipping the cloak over her suit, sure that they’ll be the best magical duo since… come to think of it, Trixie wasn’t sure how many famous magical duos there were. Well, then they’ll be the first!

Once Twilight was dressed in the thick, comfy cloak, and the big, puffy hat, Trixie passed her something else to put on as well – a pair of costume-glittery anklets, oversized so they would fit on the puffy fox-suit she was wearing just above the paws.

They were a bit of a struggle to get on, but Twilight did it, and then she put on the next thing as well – a similarly glittery ring which went around one of the toes of her paw-mitten.

Next was a staff, one which looked nigh useless for actual magic but which did lend a certain style.

The thing Trixie passed her after that was a large, puffed-up collar, and Twilight was about to put it on – then she refocused, and actually looked at it. “What's this?”

“It's to mark you as being the familiar, of course!” Trixie answered, the tail of her feline costume flicking idly back and forth.

“But… I thought you said you were the familiar,” Twilight replied uncertainly, wondering what she was missing.

“Oh, of course Trixie is the familiar,” Trixie said readily, taking the collar back and turning it to show the stone at the front – a stone which glittered. “But doesn't this look positively wonderful?”

She moved it so it caught the light. “Any witch would look so cute wearing this – and any familiar would look cute, too, showing how they're the familiar...”

Her voice dropped a little, as her own eyes drooped slightly – falling into her own trap just as fast as she was ensnaring Twilight. “Such a lovely, cute little symbol of… of…”

Trixie yawned, and Twilight took the collar. Neither of them noticed as Discord made a discreet pass with his claw, so there were two collars – one of which Twilight took, to put around the puffed-up neck of her outfit just above the cloak, and one of which Trixie slipped around her own neck.

The two curled up next to each other, Twilight’s head resting on Trixie’s puffy rump as they two began to drift off to sleep. Discord looked over to the others, each one stuck in their own puffy predicament. Cadence was now so overly frilly and floofy, she could do little more than lean up against her puffy Shining, while Cadence suddenly puffed to reveal herself to be Gilda. Cadence gasped, glaring at the gryphon who just laughed some more, only to start yawning as well. As much fun as she was having, Gilda did always feel a little tired after a good pranking.

Daybreak and Nightmare’s bickering continued, but neither was really in any position to try and escape, with their plump selves squished so snugly together. Even Starlight’s bounces were starting to slow, the astronaut dressed pony starting to tucker herself out…

She drifted down onto a pile of star and moon shaped pillows, snuggling into one as she wiggled her rump happily. She gave her pacifier a few suckles as she too began to drift off to sleep. Shining reached down to pull Cadence into a hug, or at least he did the best he could considering both of their overly frilly and floofy costumes.

Feeling proud with himself, Discord clapped his hands as the lights began to dim and mattresses appeared all along the floor under each pony.

“H-hey,” Ember protested, her voice a bit muffled. “I'm… not tired...”

“Don't be ridiculous,” Discord dismissed, waving his hand dismissively. “It's nap time for Princesses, of course.”

The words seemed to hang in the air, and Ember yawned – suddenly feeling a lot more tired than she had even seconds ago. She shifted a little, still not wanting to just drop straight off to sleep, but was too tired to object when Discord put a large bottle of warm milk in her claws and guided the nipple into her mouth.

All the other sleepy students – pony and non – were similarly bottled-up, and then Discord put on a bit of soothing music.

To Gilda, struggling to stay awake, the combination of the warm milk and the soft music and the snuggly sleeper she was wearing was almost totally irresistible. She yawned indistinctly, then her eyes closed and she drifted off to sleep.

After some indistinct but pleasant, warm, comfortable dreams, Twilight suddenly found herself awake as suddenly as the morning of an exam. She looked up, a little confused, and saw Discord standing over her.

“Just in time!” he said, tapping a watch on his wrist. “It's time for the graduation ceremony!”

“Gradu… wha?” Twilight asked, looking up at Discord. She tried to push herself up, only to find herself already sitting in a chair. All around her sat the others, each wearing a bright pink cap and gown, the latter of which did nothing to hide the fact each was wearing a thick puffy diaper beneath it. She was about to ask Discord something again when he simply shushed her and pointed to the front of the room.

Standing at a lectern was another Discord, this one wearing tiny glasses perched at the end of his snout. “Ladies and Gentlecolts, we’re here to celebrate the passing of blah blah blah blah…” Discord’s words faded into incoherent gibberish as Twilight tried to figure out what exactly was going on. “Our first graduate, Twilight Sparkle!” The Discord at the front suddenly said.

Twilight jumped a bit in her chair, the others turning to watch as she got out of her chair and waddled towards the front of the room. “Uh… t-thank you?” She asked. Discord shook her hoof, handing her a rolled-up piece of paper.

“Congratulations, Sparkle! Top marks in the class! You must be very proud! It’s just a shame you’re already an alicorn, so I suppose presenting you with a princess-ly crown will have to do for now.”

Discord produced a bright shiny tiara and placed it upon Twilight’s head before clapping, the others in the class following suit.

Twilight sat down again, feeling her diaper crinkle as she sat on it, before suddenly realizing what Discord had said. “Wait, already an-”

Discord was already consulting a large piece of paper, the top of which had bent towards them as he read. Twilight noticed that there were cutie marks on it, and stars as well – clusters of them next to the cutie marks of every pony in the room, as well as two symbols which looked like they represented Gilda and Ember.

“Shining Armor!” Discord called out, and the white-coated Guard Captain took the same path his sister had to the front.

“Now, your performance got much better towards the end of the class,” Discord told the somewhat confused stallion. “Your overall score was very good, and so you get our highest qualification. Literally.”

Shining accepted the diploma Discord gave him, seeming to still be waking up, and half-furled his wings. Then he noticed what he'd just done, and nearly fell over.

“Shining!” Cadence gasped. “You… you...”

“Quieten down there,” the first Discord said, not unkindly. “I realize it's quite a shock, but yes – this is a Princess Academy. What did you expect?”

He guided Shining to sit down, producing just the same kind of crinkle as before, and Cadence gave her husband a tearful hug.

“Celestia, Luna!” The two looked at each other, as if they only now noticed they weren’t stuck in the suits anymore. They waddled to the front, neither wanting to mention what had happened in the class. “I’m very proud of you two! You’ve set the perfect examples for what princesses are to be like! You’ve truly outdone yourselves. Just be sure not to slip back into bad habits, shall we?” Discord snickered, patting both of their diapers. Both princess’s padding pulsed, Celestia’s growing an orange and gold pattern while Luna’s became a pitch-black Nightmare style. They nodded, hurrying back to their desks in hopes that Discord would soon forget about them and not stuff them back into their suits.

Next up were Trixie and Starlight, Discord tutting a bit. “Fairly standard. Still, you do pass, and I hope that our dear Starlight continues work in the subject of Over-Poofology.” Discord snickered, indicating Starlight’s diaper, which was just a bit thicker than everyone else’s. Starlight blushed, Trixie glaring at Discord.

“Standard? Trixie is by no means standard! She is just as good as Sparkle, and demands the same treatment!” She said, stomping her hoof. Discord laughed, patting Trixie’s head as her wings flared up.

“Ah, still the master of tantrums, I see.”

“Ember, Gilda!” Discord called the next two up together, each waddling to the front of the room.

“Now, while you two did have some… issues, I’d still say you’ve each earned your horns!” Discord snapped his fingers, and the two began to glow brightly…

...only for the glow to fade again, leaving no noticeable changes whatsoever.

“...uh...” Gilda began, trying to sound as diffident as possible. “Should… there be a difference?”

“Of course there's a difference!” Discord said, crossing his arms and tapping his foot. “Phenomenal cosmic power! Isn't it obvious?”

The other Discord leaned over and whispered in his ear, and the Discord who'd been speaking rolled his eyes.

“Fine,” he grumbled. “No appreciation for subtlety, some princesses. Look at your diapers.”

Ember was the first to do so, and spotted the change in seconds. “The tape has a horn on it,” she reported, trying to somehow look like the crinkly garments were nothing to do with her even though she was wearing them. “Is that significant?”

“Of course it is,” Discord replied. “Your diapers will always have that mark on the tapes, as an indicator of your power.”

Gilda coughed. “What about if we're not wearing any stupid diapers?”

“What an odd question,” Discord dismissed. “Of course you'll be wearing diapers. Now, just say 'super pretty princess power', and you'll activate the transformation.”

“Super pretty princess power!?” Gilda repeated, incredulous, and her diaper promptly began to glow – light shining from the tapes – before spreading to cover her completely in less than two seconds.

When the glow faded, Gilda was wearing a diaper-suit of herself – one which most definitely did have an alicorn horn, as well as a ridiculously silly princess-type outfit that wafted in the slightest breeze.

“Oh, come on,” she groaned.

“To revert, simply say 'my Princess duties are done for now,'” Discord exposited, shooing them both back to their seats.

“Alright, everypony! Good luck in the real world! And don’t forget to tell everypony what a fantastic aide Discord’s Princess Pampered Padding Powdered Primary School (Name not final) was for you!”

With a bright flash of light, Spike’s comic began to shake and flutter, before several thickly padded princesses came falling out of it on top of him. He groaned, trying to push himself free of the crinkly rumps as they rolled around on top of him. He managed to free his head, finding Discord standing over him and brushing his paws clean.

“Welcome to your first class of Princess school, Spike! I hope you’re ready to learn lots of puffy prissy things!”

Spike looked around, thoroughly confused. “Wait, but… I thought I finished the story?”

Discord nodded, lifting Spike up. “Yes, you finished the first issue, and thanks to that, you get to be part of the second issue! All those subliminal ads I put in really seemed to work, didn’t they?” Discord laughed. Spike looked down at the pile of ponies, his eyes widening as he realized they weren’t Twilight and her friends, but ponies from all around ponyville! Lyra, Ditzy, Colgate…

Discord dropped Spike down into his desk, the dragon’s diaper puffing out foal powder as he did while the draconequus wandered to the front of the room. “Now, lesson one: Everything and Anything to do with diapers…”

Author's Note

And that's that for the story.
Discord's not totally heartless, he's just a massive troll.
