Gilda's revenge prank on Pinkie Pie does not go as planned.

Furious at the realization that her best friend has been stolen from her, Gilda plans her revenge on the dweeb who did this to her: Pinkie Pie.

A Dish Best Served Cold

It wasn’t a quiet day on the outskirts of the dweeb-filled town of Ponyville. Not a quiet day at all.

Sure, the wind wasn’t whistling, the sky was still, no animals were out and about to cause a ruckus, and there weren’t even any wimpy ponies nearby to whinny, or whatever it was wimpy ponies did to make noise.

There was, however, a rather irate and aggravated griffon, who was pacing about in mid-air creating a cacophony all on her own. She grumbled, growled, and even yelled at all the stupid nothing around her in a futile effort to expel her misplaced rage.

“Stupid, dumb, wimpy, dweeb!” Gilda screamed, channelling her eagle half into a primitive screech at the sky. “Why did that pink moron have to ruin everything?”

Everything being Gilda’s day trip to the lame land of Equestria to hang out with the only non-lame pony in existence. Formerly non-lame pony, she should say.

“Stupid flip-flopping ex-friend,” she grumbled to herself. Though her rage towards that pink menace was vast, her bitterness toward Rainbow Dash was a far colder variety.

After everything they’d been through, she would side with that annoying dipstick over her? Gilda? The only awesome thing in her boring and dull life?

“Stupid, stupid, stupid…” Gilda’s internal thesaurus had broken down quite a while ago, leaving her with little else in way of synonyms. Thankfully ‘stupid’ summed everything up pretty nicely.

“How could she not see how all those pranks were stacked against me?” Gilda caught herself mid-huff. Dash had said she’d had a hoof in setting up all those pranks, hadn’t she? Could that mean…. “No…”

Gilda caught herself again. She shouldn’t be so quick to dismiss Dash as innocent in all of this. Pinkie Pie had set her up for all of them so perfectly that there was just no way Dash hadn’t told her about them. And the way she acted all innocent too! As if she was as dumb as a foal; which she probably was, given what Gilda had seen.

But, how could Rainbow Dash do that to her? “Unless…” Gilda scratched the underside of her beak.

Rainbow had seemed pretty chummy with all of those dweebs. Clearly their dweebiness had dweebed off on her, somehow. It was the only explanation!

“Those… dweebs!” She really should fix her internal thesaurus soon. “I’ll bet they’ve got Dash wrapped around their hooves. They must’ve been making her believe I’m the bad guy here! That pink one probably had her think about everything… like an idiot!”

Gilda pounded a fist into her open claw. She knew what she had to do; she had to get her friend back and un-dweebify her. And soon.

“It shouldn’t be too hard,” she reasoned. “All I gotta do is show her what big dweebs her prissy pony pals are. Starting with that pink one.”

But how to do it? Threats and intimidation were Gilda’s bread and butter, but they didn’t work on Pinkie Pie, which was frustrating. It was like that dweeb was too dense to know any better. She just went right along, prancing and pranking like no one’s business.

Wait a second… Gilda snapped her claw. “That’s it! I’m gonna prank the living daylights out of that stupid dweeb!”

It was perfect! Using her own tactics against her was a guaranteed success to humiliate her. But it wouldn’t be with joy buzzers or tick candles. That was foal’s play as far as Gilda was concerned. She would show Pinkie a real prank. But it had to be good and humiliating if it was going to snap Rainbow out of her dweebishness.

The image of Pinkie’s oblivious, stupid face came to her mind and gave Gilda pause. “What would humiliate that stupid foal?” she wondered aloud.

Actually…

Making her look like a stupid foal in front of everypony was probably just the trick. Nothing else would get through her thick, pink skull than to be seen as a foal by her ‘friend’ Rainbow Dash.

If Gilda had a handlebar mustache right now, she be twirling it maliciously. She settled instead for rubbing her claws together, just as maliciously as a mustache twirl.

“Alright. So all I’m going to need is an industrial sized spring, some rope, and an adult sized diaper.”

Well, why stop there? Gilda was sure she could make this prank even more humiliating for Pinkie Pie. After all, she wasn’t just saving her friend from the clutches of dweebdom, but was also getting a little revenge for all those wimpy pranks earlier.

Gilda grinned evilly. Time to get to work.

Sweet Delights hummed to herself as she tapped a few keys on the cash register. “Ten bits, please,” she said.

The exact change was dumped onto the counter before her and she barely had time to process it before a green blur grabbed the pack of diapers next to them and fled the store.

Sweet blinked, before sweeping the bits into her white hoof and dropping them off into the register. She never understood why ponies got embarrassed about buying supplies from her. Was shopping at an adult foal store really that humiliating?

She glanced up at the shop around her, taking the time to brush her curly blonde mane out of her eyes. The aisles of her store met her gaze, their pink coloring almost blinding in the bright lighting of the room. The wares they held only served to add to the chaos, with more bright pinks, along with purples, yellows, and baby blues covering the packages of diapers, pacifiers, and oversized foal toys. All of this, was of course, complimented by the magenta wallpaper that bore soft pink swirly designs.

Sweet blushed. Maybe it was the lack of subtlety in her store that embarrassed so many.

She turned back to the cash register to close it up, debating with herself if maybe changing the store to be a little more low key would be a good idea. After all, it wasn’t like business was bad or anything. Plenty of adult foals lived in Ponyville. It was be a hassle to do so anyway.

But at the same time if it managed to attract the more shy potential clients out there…

FWOMP!

Sweet was jostled back to reality when a bundle of goods was dropped onto the checkout lane. She glanced up to see a butter cream yellow sundress with a set of matching, massively poofy booties, and bonnet right next to it. On top of them was a pack of the largest diapers the story could offer (twenty centimeters of pure padding, to be exact), and a strapable pacifier to rival their size with a massive rubber bulb.

It was quite a surprise to see so much be purchased at once. Most customers were a little more conservative, buying only the smallest amount at each visit so it would be easier to hide on their way out.

But that wasn’t the biggest surprise. That honor went to the customer herself. When Sweet Delight looked up, she found herself face to face with the surliest griffon she’d ever seen.

Also the only griffon she had ever seen, but that didn’t detract from the pure scowl that graced this particular cat-bird’s face.

“Ring me up,” she said with a rough and tumble voice that made Sweet’s skin crawl.

“Uh… okay.” Sweet happily took the opportunity to break eye contact with the griffon to start punching numbers into the cash register.

They were silent for just a brief moment, save the clacking of the register’s buttons. Then--

“You got muscle relaxers, right?” The griffon grunted.

Sweet looked up, eyebrow raised.

“The sign says ask the cashier, so do you, dweeb?” She pointed with her… sharp claw at the notice on the back of the register.

“Y-Yes,” Sweet stammered, taken aback at being called a ‘dweeb’. Whatever that was. “It’s for those who wanted a more… immersive qualifying experience.”

“Sounds right up my alley,” the griffon said. “I’ll take a bottle of the strongest you got.”

“T-The strongest?” Sweet Delights asked. “You sure that won’t be too intense for you?”

“Do I look like a wimpy pony?” the griffon barked. “Now, give me the strongest stuff you got. Not the weak sauce garbage, I’m talking the crap-your-pants-in-an-instant kind of stuff.”

“Oh my…” Sweet definitely had an elixir like that. She reached down below the counter and unlocked the small chest she kept back there. Never breaking eye contact with the griffon, she produced a small vial of dark blue liquid. “This should be what you’re looking for.”

The griffon leaned in, squinting. “This? Really? That’s puny!”

“Trust me,” Sweet said. “One drop of this is enough to give even a griffon like yourself the muscle control of a foal. Er… hatchling?”

The griffon rolled her eyes. “Yeah right. That wimpy looking stuff?”

Sweet’s features compressed. It was one thing to be talked down to by a customer, it was another to have her wares be doubted. Especially by some...griffon? And somegriffon so rude on top of that!

“Listen here, this muscle-relaxant is specially brewed by a zebra who lives in the Everfree Forest. I’ve personally tested it out and I can safely say that a vial this size is strong enough to leave you with the body of a foal for a full day.”

The griffon leaned back, rubbing her chin with hesitation. “I dunno, that’s probably not enough. Gimme all of it.”

Sweet nearly choked. “A-All of it?”

“Did I stutter?” The griffon narrowed her eyes. “All. Of. It.”

Sweet Delights gulped, and pulled out the chest to reveal twenty-four more vials of equal size. “W-Will this do?”

The griffon grinned menacingly. “That might just work, dweeb.”

While Sweet could hardly believe she was about to sell all of this to one customer, it was still inarguably the biggest sale of the day-- no, week! She hastily tapped in the numbers to the register as the griffon picked up a vial to inspect it further.

“By the way,” she said.

Sweet glanced up. “Uh, yes?’

“You know where I can find sprayable glue? Like, basically instant cement type stuff.”

Sweet Delights blinked. What exactly was this griffon intending to do?

“Stupid expensive potion garbage.” Gilda’s wallet was feeling substantially lighter after all the shopping was done. Seriously, was that diaper-selling dweeb serious with that price tag? It was highway robbery!

But, as long as it did the job, she wouldn’t complain. ...Probably

Gilda overturned the twenty-fifth vial, letting the dark-blue liquid spill out onto the pacifier, only adding to the globby mess. She let the vial fall to the ground as she finished tying the pacifier into place.

With a grin, Gilda flew back to admire her handiwork.

The lonely tree that sat in the middle of this field was now given purpose in the form of Gilda’s revenge prank. Hidden among its many leafy branches were the instruments of Pinkie Pie’s humiliation.

All the stuff she’d bought at that stupid adult foal store (seriously, how wimpy were ponies if they would pay to wear diapers. If Dash did that too then maybe their friendship was beyond salvaging.) was now carefully planting within the tree. They were each tied into the perfect position based on Gilda’s expert eyeballing when it came to trajectory. The best part though was the liberal amount of glue she had sprayed on the inside of everything, ensuring there would be no easy escape for Pinkie once she fell victim.

Gilda swooped down to the ground, landing right next to the trigger for her trap. A slice of pie, resting on the grass. The pie was right on top of a platform, which in turn was right on top of a massive spring, ready to be set off once the unsuspecting pony offset the perfect balancing act set up.

Gilda grinned, really in need of a handlebar mustache to twirl.

The trap was in place, the bait set, and the cogs in motion. She’d already sent anonymous letters to both Pinkie Pie and Rainbow Dash, asking them to come to this spot before sun down.

She glanced up at the sky, seeing the sun already beginning to dip to the horizon. Her grin widened.

Everything was too perfect. Soon Pinkie would be humiliated and Rainbow would be begging for Gilda to be her friend again.

“La lala lala~” A singsong, annoyingly familiar voice hit Gilda’s ears.

Looking around, she saw Pinkie Pie skipping through the field and heading right for the meeting spot. Gilda almost froze, worried she’d been spotted, but noticed her prey’s eyes were closed.

She darted around the tree, hiding against the other side of the trunk. Peeking just around the corner, she could see Pinkie approach even closer now. Looking up, she saw Rainbow Dash flying towards the tree as well.

Her grin was going to split her face in two if she kept this up.

Resisting the urge to snicker at what was about to happen, Gilda just leaned against the tree trunk and prepared to watch the show.

“Huh?” Pinkie stopped her skip as she saw the slice of pie lying on the ground. She tiltled her head and looked it over.

That’s it. Gilda chewed the inside of her cheek. Go on, have a bite you dumb, dweebish foal.

Pinkie knelt down right over the spring and sniffed at the pie. Gilda clenched her claw, knowing this was it. She saw Dash beginning her descent and nearly squealed.

“Pinkie?” Rainbow asked as she landed. “You wanted to meet me out here?”

“I wanted to meet somepony out here,” Pinkie replied. She picked up the pie, taking a step forward. Gilda braced herself.

Nothing.

“Check out what I found,” Pinkie said. “It’s cinnamon apple pie!”

Gilda could hear glass shattering. It took every fiber of her being not to scream. WHAT?!

That dweeb was standing right on the spring trap! How was she not twenty feet in the air right now?

“Oh, nice.” Dash smiled. “Mind if I have a bite?”

“Sure, I love sharing free pie! Or any pie for that matter. Did you know Gummy once found a pie that--”

Gilda wanted to scream in agony. Sharing? Dash really does need my help. She watched the spring as Pinkie stepped off it without a hitch and her jaw tightened with fury. You’ve gotta be kidding me!

That spring had been set to go! It was begging to launch something. How had that pink dweeb completely avoided it!

As Rainbow Dash and Pinkie walked off, engrossed in their dweebish story, Gilda stepped out from behind the tree, a furious scowl on her face.

How dare that spring not work! She approached the platform cautiously and gave it a little poke. Nothing.

Curious, Gilda pressed her claw against it. Again, nothing.

With a harrumph, she pushed down with both claws. What do you know? More nothing.

Did I do it wrong? Gilda shook her head. She was a pranking master. No way this thing was broken.

Just to be sure, Gilda stood on it. Nope, still no reaction from the spring.

You gotta be kidding me. Now angry, Gilda gave a short hop. The platform creaked at the movement, but didn’t budge.

With a growl, Gilda leapt into the air and slammed her whole body down, determined to see the spring react.

FWOOSH!

Gilda blinked, going from ground to mid-air in a split second. Her body flipped and flailed in the air, as she saw the spring below for a brief second, now hanging out. It took only a second to realize that it had finally worked, but by then Gilda had already opened her beak and started screaming.

Then she landed in the tree.

A few feet away, Rainbow Dash and Pinkie Pie turned at the sound, but Gilda couldn’t see them through the leaves.

Her body tumbled down the branches, her claws and paws getting knocked into something soft that quickly encased them. Her eyes widened as she realized it was the booties.

She didn’t have long to process that, before her body slid into something new. Silky fabric suddenly covered her and her limbs flailed through sleeves as Gilda realized the prissy dress she’d set up was now around her body. The ropes holding it in place unraveled as her weight filled the dress, sending her further down the tree. Which meant…

crinkle crinkle

Gilda’s waist smushed into a pre-wrapped diaper that had been waiting just below the dress. It’s poofiness forced her legs apart as they slid through the waiting holes.

Her diapered rear was buffeted by the next branch, sending her spiraling forward. Her mouth was still open from the scream, which was a bad move.

Next up in her line of prank-traps was the pacifier, which her beak fell right into. The strap snapped into place against the back of her neck as she knocked it free of it’s spot. Its bulb invaded her mouth, it’s massive size forcing her jaw open. The many layers of muscle relaxant coating the pacifier now found itself inside Gilda’s mouth. Just from sheer force of her fall, globs of it already jumped down her throat, and the effects were immediate.

Her whole body suddenly felt numb. It was like her strength leaked out of her, and she found that even in the midst of her fall, she couldn’t so much as flail her limbs properly anymore. It was like her control had been sapped away.

Using every ounce of willpower, she managed to turn her body ever so slightly… just in time for the frilly bonnet, the last piece of her prank puzzle, to latch on to the back of her head. Her peripheral vision was cut off immediate by the newest addition to her outfit, but that was the least of her worries.

Gilda found she could only give a muffled whine as she fell to the ground. Her poofy butt hit the grass first, cushioning the impact for the rest of her. She flopped forward, and struggled to move.

Her limbs responded lethargically. Her foreleg slowly twitched, despite her commanding it to help her stand. Gilda was at least able to lift her head up out of the grass, but only barely.

Even if she could move, Gilda realized that wouldn’t do much for her. Her new outfit, from the booties to the bonnet to the dress, to even the inside of her pacifier strap, were all covered with the glue-spray that she had been oh so happy to apply. She could feel it harden against fur and feather alike, and wanted to rip it off her body as soon as possible. Except… her claws were covered by the booties, rendering their shredding power null.

Weakly, Gilda tried to call out for help, but her mouth was so lax that she only suckled the pacifier it held, allowing more of the muscle relaxant to enter her body.

And then her bowels and bladder weaken with a sickening squeal from her gut. She knew what was about to happen and whined loudly.

“Yeah, I heard it too. I think it came from over here.”

Gilda’s eyes bulged. Dash’s voice!

“What do you think it was?” Pinkie’s as well.

Oh no, they’re going to see me like this… and I’m about to…

Gilda struggled to flee. Her wings were pinned by her fillyish dress, but with the muscle relaxants they wouldn’t be too useful anyway. She tried running, but even summoning what little strength she still had, the best she could do was a weak half-crawl. To make matters worse, her beak couldn’t seem to stop suckling now, exasperating the problem.

Not to mention trying to move only pushed herself closer to having an accident.

“Holy cow! G...Gilda?”

Gilda winced, and weakly turned around. Pinkie Pie and Rainbow Dash stood right behind her, jaws touching the ground at the sight before them.

“Mmmph mrr mrph!” Gilda whined, trying to explain the situation and failing oh so miserably.

It wasn’t long before the surprise on the two pony's faces turned to amusement.

“What are you wearing?” Rainbow asked, hoof not even covering her mouth as she broke out in a laugh.

“You look soooo cute!” Pinkie squealed, at least bothering with a hoof over her mouth.

Gilda whined and whimpered, praying that she could hold back what was about to happen. This had just cemented herself as a dweeb in Rainbow Dash’s mind, no doubt. But even with that, she couldn’t have her seeing--

Too late.

Gilda’s poofy butt instinctively raised, tail hiking in preparation. Rainbow nearly choked on her laugh as she saw this, while Pinkie just gasped.

It started with her bladder giving way.

A tiny, dribble amount of urine escaped, and then the floodgates were open. A hiss could be heard as Gilda peed herself, a steady stream of liquid pouring forth only to be thirstily soaked up by the diaper she wore. A blush dominated her face as she wet herself, but that wasn’t even the worst of it.

She didn’t even need to push as her bowels followed her bladder’s lead. A hot, steamy mess roared out of her butt with a resounding fart and slammed into her padding. Her diaper crinkled as it expanded, the feces staining it brown almost upon impact despite it’s thickness. Gilda grunted with exertion as halfway through she found herself pushing anyway.

Her diaper sagged as her poop loaded it up, bulging out in a chunky mess. The stench of crap and piss mixed in the air and hit her nose, which was coincidentally the only way she could breathe at the moment.

Gilda gagged at the smell of fresh manure, whining as her accident finally ended. Her butt fell back to the earth below, squishing the wet padding and stinky mess together in unholy matrimony.

All of this, in front of Rainbow and Pinkie.

“Holy… Holy mother of Celestia.” Dash plugged her nose. “G, are you serious right now?”

“P.U.” Pinkie waved her hoof viciously, trying to dissuade the stink. “That’s one big accident.”

Gilda’s face was red from pure embarrassment. To think that this had to happen to her in front of these two of all ponies! If Pinkie hadn’t been so stupid that she broke the spring somehow, it wouldn’t even be her in this mess.

“I think, maybe we better go, Pinkie,” Dash said.

“And leave her like this?” Pinkie asked. “That feels kind of… mean…”

“Not really. She probably chose to wear and… do all of this.” Rainbow said.

“MMPH!” Gilda complained.

“See,” Dash said, taking that as proof. “We should give her some uh… alone time.” She leaned in and whispered. “Besides, looking like this I feel like talking to her even less right now.”

“Okay,” Pinkie sighed. “Oh, still up for that pie?”

Dash took one look as Gilda’s filthy diaper and cringed. “I’ve lost my appetite.”

“Okay then,” Pinkie waved at the humiliated griffon. “Bye, Gilda. I hope you enjoy… whatever this is.”

Gilda whimpered as the two turned and scampered away. She wanted to yell back that they were dweebs… or something, but wasn’t really in a position to do so.

Paralyzed by both the muscle relaxants and humiliation, Gilda just laid around in her filthy diaper, still suckling on the pacifier uncontrollably. Finally, she crawled forward a little more and thought about what to do to escape this mess. She hadn’t designed this prank with a failsafe, so she was going to need some help getting out of everything. Between the glue and the muscle relaxants, even with some help she could be stuck like this for quite a while, even with help.

She almost regretted letting those two go. Almost.

Continuing to crawl, she winced as the mess in her diaper spread with each movement and tried to think of what to do.

Maybe that wimpy diaper salespony can get me out of this.

With a grunt, Gilda realized that was probably her best option at this point and struggled to crawl back to Ponyville. Seeing the large, crowded town she would have to go through to get to the adult foal store, she whimpered.

Her humiliation wasn’t over yet.

...Stupid dweebs...
