“All right, let’s try this again,” Luna said, once they were in the dream realm. “I’ll just link myself to your dream, and we’ll see where you end up going.”

“Why me?” Celestia asked. “Why not try to see where you end up going?”

“I am the Princess of Dreams!” Luna said.

Then coughed.

“Was, the Princess of Dreams,” she amended. “So I should be in charge… but if you insist, I’ll link you to me and then we’ll see where my dream ends up going.”

“Oh, so there actually wasn’t a reason?” Celestia said, with a shrug.

Her diaper crinkled, and Luna frowned slightly. Something about this was… odd. Unusual. It wasn’t quite what she was expecting…?

She shrugged her wings, unable to work out what the issue was, then linked the two of them together with a magical tether and cast a spell to shuffle them into a random dream.

Whatever it was, the Nightwear memorial should be there somewhere…

...Celestia trotted through the door of the school-house, then held the door open with her big crinkly diaper-butt to let Luna in after her.

“Ah, good,” the teacher said. “I’m glad to see you two have arrived on time. You were nearly late!”

“I wouldn’t want to be late,” Celestia admitted.

“Nor would I,” Luna agreed. “But we aren’t late, so we don’t need to worry about that.”

The teacher smiled. “That’s right,” she said. “There’s a lot of things you don’t need to worry about. In fact, that’s what this lesson is about…”

"Um... what lesson are we here for again?" Luna asked with a bit of a sheepish blush as she looked around to see what the lessons were about. The words on the chalkboard said something, but Luna was finding it hard to understand what it said...

"You're here for Wonderbutt training of course!" the teacher said, sounding suspiciously like Nightwear Luna didn't recognize the voice, the large alicorn was wearing a Wonderbutt costume and a big, poofy diaper, but the outfit prevented either princess from telling who the teacher was.

"O-oh... um, we're actually needing to look for a statue..." Celestia said hesitantly, not wanting to get drawn into a long class when they had a goal for tonight. Plus the name seemed a bit off from what she remembered..?

"That's why you're here to be a Wonderbutt! Wonderbutts learn how to travel fast in big, poofy pampers and show off their crinkly butts find things! You two are wearing thick, poofy pampers already, so you're clearly Wonderbutts in training!" the Teacher said. "Now get ready for class and put on your Wonderbutt uniforms!"

"Oh... well if it will help us be faster later..," Luna said, putting on the tight fitting outfit that left nothing to the imagination, her poofy padding included.

Celestia did the same, and the princesses hesitantly took their seats. "So... where do we start?" Celestia asked, just as their goggles started to turn shimmery and shiny and swirly.

"The first rule of being a Wonderbutt is to obey," the teacher giggled.

“S-so, umm… how do we…?” Luna tried asking, not sure if she should focus on the goggles or focus on what she wanted to learn, or even both. The goggles were so distracting, but… were they part of the lesson or not?

She wriggled back and forth a bit, settling in for the lesson.

“Oh, it’s quite simple,” the teacher told her, and by extension also told Celestia. “Actually, learning to obey is more about learning how to not do something. The simplest thing to do is to obey, to do what someone tells you to do. But to think about it is much harder, and that’s something you’ve learned to do for a long time… but to obey you just need to learn how to not think about something first. Just do it before you have time to think about it.”

Celestia frowned, through the swirling patterns. “But… isn’t, thinking about something good?”

“Not if you’re going to be a Wonderbutt,” the teacher said. “Imagine what it would be like if the head Wonderbutt told you to do something and everyone thought about it first! They’d all go in different directions and wouldn’t act in time, and it would be complete chaos… but low ranking Wonderbutts listening to someone who’s higher ranking than them makes sense, doesn’t it?”

She chuckled. “Of course, I understand it’s going to take a while to learn that. So we’re going to start with some simple lessons… if you’re having trouble thinking, just focus on the goggles and their patterns, it’ll help you stop thinking. But first, here’s what you need to repeat after me… Wonderbutts don’t think. Wonderbutts obey.”

“Wonderbutts don’t think,” Luna repeated. “Wonderbutts obey...”

"Wonderbutts don't think," Celestia said as she followed along, "Wonderbutts obey..."

"I'm a trainee Wonderbutt," the teacher said.

Luna and Celestia nodded along: that made sense after all, they were in class right now.

"I'm a trainee Wonderbutt," they repeated.

"Everyone outranks trainee Wonderbutts," the teacher said. That made sense: trainees were just learning after all.

"Everyone outranks trainee Wonderbutts," the Princesses Wonderbutt Trainees repeated.

"I'm a good Wonderbutt," the teacher said, making Luna and Celestia feel all fluttery. They were good Wonderbutts, right?

"I'm a good Wonderbutt!" Celestia and Luna said together enthusiastic, earning pats on the head.

"Good Wonderbutts Let Thoughts Flow Out," the teacher said, turning around to display her rump as she relaxed, a gentle pssssshhhhh letting the pair know their teacher was really good at letting all those pesky thoughts flooooow out, her Wonderbutt onesie uniform snaps popping open one after another to reveal a soggy swirly diaper that was getting bigger, soggier, squishier, swirlier... and the teacher began to shake her rump from side to side, drawing in Luna and Celestia's gaze as they felt their own diapers growing warm as they let the thoughts flow out...

Neither Celestia nor Luna was paying much attention to how many times they repeated their instructions. That would have been thinking, not obeying, and they knew good trainee Wonderbutts didn’t do that.

So there was just a haze of soggy dizzy obedience and repetition, over and over again, letting the lesson sink in…

...until there was a bright flash in front of them, as a TV turned on.

“Now, since you’ve been such good Wonderbutt trainees,” the teacher said, making both Celestia and Luna squirm with happy obedient thoughts… “...you get to watch the next bit of the lesson about what Wonderbutts do as a cartoon!”

She clicked the remote, and a colourful cartoon spiral appeared counting down until the lesson began.

A cheerful little cartoon-Nightwear appeared on the screen, telling them to listen closely like good Wonderbutts, because she outranked them, and the addled alicorns accepted that easily. Then the cartoon began talking about the duties of Wonderbutt trainees, and how they flew around and listened to anyone who outranked them and watched out for sneaky infiltrators who might try to steal Wonderbutt diapers secrets and obeyed and wore whatever they were told to wear and obeyed...

As they watched the swirly, shimmery show, Luna and Celestia gradually waddled closer and closer to the screen, letting thoughts flow out, listening like good Wonderbutts...

And just like that, they stepped through the TV screen and into the show itself! Above them, they could see the screen of the TV leading back into the class room, the view mostly occupied by a swirly giant Wonderbutt with a moon print on it that lit up the night, the shifting, soggy moon making the lighting and shadows dance ever more swirly, shifty and dizzy...

"Wonderbutts!" a voice said, belonging to Spitfire Soggfire, the commander of the Wonderbutts! Her Wonderbutt uniform had a thicker, poofier diaper then they did, clearly marking her as the leader. (Everyone outranked trainee Wonderbutts, after all.)

"Yes Ma'am!" Luna and Celestia said, trying to stand as much to attention as their swollen, sloshy diapers allowed.

"We've heard news that Shadowbutts, Pooffins, Sissybutts, Draaagons and Changlings are coming to steal our diapers secrets! Your task for today is to Submit guard the diapers secrets and obey repel anyone who comes to steal them!" Soggfire said.

"Yes Ma'am!" Luna and Celestia said, then Celestia paused.

"Um, what are Poofins and Draaagons?" Celestia asked sheepishly.

"Poofins are Poofy Griffins, and Draaagons are Diaper Dragging Dragons silly! Now go to the vault and look for swirls trouble!" Soggfire commanded, the two Wonderbutt Trainees heading to the easy to find super secret hidden vault to Soak and SubmitStand guard!

“So… how exactly are we going to be able to tell any of these infiltrators if we spot them?” Celestia asked after some minutes, frowning.

“I guess… that’s why we need to be alert?” Luna replied. “Uh, if it was easy to spot them then they wouldn’t need us on the case, right?”

“Right, but if it’s really hard then how do we know if we’ve spotted them at all?” Celestia replied.

Luna considered. “Well…” she began.

“And how do we know that there isn’t one creeping up on us right now?” Celestia added. “We can each only look in one direction at a time… what do guards normally do?”

Luna shook her head. “I don’t actually know,” she admitted. “I was hoping you had an idea?”

“I think guards normally… patrol, right?” Celestia suggested. “That sounds like something guards do. They go back and forth, and, uh, march around, so they can check everywhere. Instead of standing there and waiting for someone to show up.”

“That’s a good point,” Luna said. “But we don’t want to leave this place without anyone defending it… what about if we take turns?”

“Taking turns!” Celestia agreed. “That’s a great idea – let’s do that! So… who goes out on patrol first?”

One coin flip later (Celestia had picked ‘butt’), Luna was out on patrol, her horn lit up as she waddled back and forth down the corridors of the super secret hidden vault.

“I still don’t know what I should be looking out for,” she muttered, under her breath, turning left and then right as the glow from her horn lit up the corridors.

Then she saw somepony moving up ahead.

She almost shouted, but the other pony wasn’t moving very fast and they didn’t seem to have noticed her. So she waddled up more quickly, getting a spell ready, before seeing that it was a stallion in a Wonderbutt onesie.

“Oh, it’s… what’s your name?” she asked. “I was worried you were an infiltrator.”

“I’m Shadowy Secrets,” the pony replied, smirking and wiggling his butt. “And you don’t need to worry about that.”

“I’m not,” Luna said. “...should I be worried?”

“Not at all,” Shadowy Secrets said, wiggling his butt again, and the poppers holding the flap of his onesie strained… then popped off, revealing that he was wearing a second onesie under his Wonderbutt onesie!

This one was a much more sinister, purple-and-yellow, Shadowbutt onesie, and it had a swirly pattern on it as well!

"O-oh!" Luna said, knowing she had to submit guard the diapers secrets from being stolen! "Well, um, you don't look like a Wonderbutt! So you have to go!" Luna said.

"Of course I have to go~" Soggy Secrets said, relaxing as his diaper began to warm and swell, the Shadowbutt onesie looking bigger and bigger as the diaper underneath expanded until it popped open, hitting Luna with a dizzying puff of powder. "You have to "go" too. After all, my diaper is bigger and heavier then yours. How are you going to guard if you can't beat me in a bump butt contest?"

"Have to... go..." Luna mumbled, her diaper growing even warmer and soggier as she felt her diaper swell even further.

"That's right! Now your diaper is even bigger and heavier then mine! But you have to defeat all the Shadowbutts, right? How are you gonna defeat the Shadowbutts if they know a Wonderbutt is coming?" Soggy Secrets smirked.

"Um... I'll just defeat you and figure out what to do next!" Luna said, trying to butt bump Soggy Secrets with her saggy rump, connecting with a SQUIIIIISH that made Luna feel all subby and squirmy, letting Soggy Secrets easily sit on top of her.

"I think you'll be a more fun Shadowbutt then a Wonderbutt~" Soggy Secrets giggled, layering Luna into another, extra poofy Shadowbutt Diaper and her very own Shadowbutt suit, the goggles already making shimmery swirls…

By the time Soggy Secrets had finished diapering- and suiting-up Luna, he smirked. “Oh, but you’re going to need to make sure you don’t get noticed as a Shadowbutt by that Wonderbutt guard, aren’t you? So if you’re going to infiltrate, you need a Wonderbutt disguise!”

The swirly goggles made it hard to impossible for Luna to think of a counter for that, and within a minute Soggy Secrets had fitted her with a disguise as well – a clip-on name badge that said Not A Shadowbutt.

“Remember, don’t tell anyone you’re really a Shadowbutt!” Soggy Secrets added. “A secret Shadowbutt!”

With that, he rump-bumped Luna back down the corridor, and Luna waddled along with her rump and name badge swaying from side to side…

“Luna!” Celestia said. “I see you’re back from your patrol!”

She frowned. “Are you all right?” she asked. “You look… different.”

“Like what?” Luna replied, tilting her head.

“Well…” Celestia began. “Like a Shadowbutt, maybe?”

“But I’m obviously not,” Luna replied, sitting back in her Shadowbutt sleeper with its Shadowbutt cutie marks on her flanks and Shadowbutt colouring and swirly Shadowbutt goggles

She raised a hoof, and tapped the name badge with its reflective purple-yellow-black swirl background. “Look!”

Her hoof made it swing back and forth, and Celestia leaned closer to look for a minute moment.

“..well, that does say Not A Shadowbutt,” she conceded. “All right, so you’re not a Shadowbutt, but… keep an eye out for them, I guess?”

Celestia frowned, thinking about whether she should stay, then shook her head.

Obviously she needed to go out on patrol, now, and nothing was wrong, was it?

Not far away, another royal was... very confused when she looked around. Queen Chrysalis wasn't sure who's dream this was, but it didn't seem to be one of hers. And why was there a giant soggy diaper butt shaking back and forward and back and forward and back and forward...

Queen Chrysalis Crinklesalis blinked after a bit, realizing she'd gotten distracted from her mission! She had to steal diapers secrets from the Wonderbutts, and find Wonderbutts to turn into cute, rubber suited changeling drones!

So she began to waddle towards the totally obvioussuper secret vault, trying to find a guard on patrol she could pounce on...

"Halt!" Celestia said, spotting the Changeling Queen waddling towards the vault. "Um... go away! This is for Wonderbutts only!"

Queen Crinklesalis grinned, pouncing on Celestia and tickling her sides, making the Wonderbutt flail and squeal in laughter as her padding began to drooooooop from a heavy soaking.

"Looks like you're in need of a changing! And, because I'm a changeling queen, I get to change you!" Crinklesalis giggled, changing Celestia's pamp to a big, black, rubbery diaper that began to spread on Celestia's body.

“H-hey!” Celestia protested, in between giggles, as the diaper’s rubbery-crinkly coating spread out across her body. “That’s not – stop it – you’re not supposed to do this!”

“Really?” Crinklesalis replied. “Then how am I doing it?”

“That’s not…” Celestia said, then got distracted as Crinklesalis lit her horn and her eyes began to glow green.

The spiralling, entrancing green patterns caught her attention… and, also, Queen Crinklesalis’s attention, because she wasn’t actually immune to her own hypnosis. Just… resistant.

If Crinklesalis was dizzy, though, Celestia was entranced… at least, until she felt her hooves coated in the rubbery-crinkly material!

She waddled backwards, falling over and landing with a crinkly springy sound on her black-diapered rump, then got caught up in Crinklesalis’s eyes again and felt dizzy all over again.

“Listen closely,” Crinklesalis said. “You are a change-ling.”

“I’m a… change-ling,” Celestia repeated.

“Change-lings don’t think,” Crinklesalis told her. “Change-ling drones don’t think. Change-ling drones just obey.”

Celestia nodded, blushing, as the drone-suit finished forming over her.. encasing her eyes behind green swirls.

“But Change-lings can disguise themselves,” Crinklesalis went on. “They’re great at infiltrating and pretending to be someone.”

She pulled out a Celestia suit, frowned for a moment as she wondered where she’d got it, then caught sight of the moon mooning her and stared at it for a minute a few seconds. Then shrugged.

It wasn’t important, anyway.

The black rubbery suit covered Celestia from head to toe, the rubber squeaking and squeezing her, the poofy, rubbery diaper underneath filling the suit with dizzying powder.

Over the squeaky suit, Crinklesalis promptly put her in a Celestia outfit, the Change-ling drone underneath it now suffering from yet another layer of swirly goggles and big, puffy pink pampers that pooofed out pink powder with every step, making her even more silly and dizzy and obedient.

"Now my little Change-ling drone, go and steal the diapers secrets from the vault! And when your diapers are all soggy and soaked, waddle back to the Queen of Change-lings for changing," Queen Crinklesalis instructed.

Celestia could only give a little "mrfff!" in response, fully encased in rubbery, plushy suits as she was, but she obediently toddled towards the vault, try to remember how to steal diapers instead of how to be a big dumb diaper drone...

At least it would be Luna's turn to patrol next.

Luna was still looking at the vault, wondering how to open it, when she heard a squeaky, creaky noise from the left.

She looked up, and saw…

saw…

A blushy, poofy, squeaky rubbery suit wearing-

A bad Celestia costume-

...her sister, waddling up after finishing her patrol.

“I wasn’t trying to get into the vault!” Luna said, jumping.

“Mrf,” Celestia replied.

Luna tilted her head a little, not sure why her sister wasn’t saying much, then shrugged.

“Well, I’ll… go on patrol,” she said. “And, definitely not try and work out how to get into the vault!”

“Mrf!” Celestia nodded, head wobbling a bit, and squeezed her diapers with her hind legs.

Satisfied, Luna trotted off.

“...what?” Luna asked, some minutes later.

She looked around.

No mistake, this was definitely the route… but it went through the water?

And if Luna went though that water, she wouldn’t be a Wonderbutt who was really a Shadowbutt who was really a Wonderbutt who was really a Princess. She’d be a Soggybutt.

Then she heard a shout, and saw a hippogriff with a pink coat and blue mane do a perfect swan-dive into the water.

“Wahoo!” the hippogriff announced, splashing to the surface again, and shook herself out. “Diving’s great! And, get this – there are stairs up to the diving platform!”

“...do I know you?” Luna asked.

“Oh, probably not,” the pink hippogriff replied, sitting down on her moon-themed diaper. “I feel like I should know you! But when I look at you, all I can think of is the moon?”

Luna looked up at the mooning moon, and so did the hippogriff, and a few minutes seconds later Luna shook her head in confusion.

“Oh, I’m Silverstream!” the hippogriff added. “I’m sort of a princess, only it’s because the queen is my aunt, not my mom. So my mom’s a princess and so am I. Funny, huh?”

She shrugged. “Anyway, you have a problem, right?”

“Yes,” Luna agreed. “There’s water across the path I was taking.”

“Oh, that’s super easy to deal with!” Silverstream told her. “See, hippogriffs are also seaponies!”

She giggled. “And that means, all you need is to disguise yourself as a seapony, meaning a hippogriff, and the water will know not to get into your diaper!”

Luna was nodding along. If she wore the outfit, she'd be extra under cover! No-one would realize she was a Shadowbutt! So when Silverstream offered the suit, Luna wiggled her already poofy and suited bottom into the new puffy suit and diaper... and almost immediately started to potty dance a bit.

The new suit was all slick and squeeezy, and it was squeezy right on her bladder, and it filled her head with Soggybutt thoughts as the head began to glow with more hypnotic swirls.

"So I just... go across the water?" Luna asked, even more dazzled then before.

"Yup! It's easy!" Silverstream said, guiding Luna to the water.

The suit immediately got even puffier and poofier and squeezier as it inflated to keep Luna above the water, the inside filling with powder as Luna was filled with silly, sloshy, ditzy, dizzy thoughts.

After idly paddling around, she sorta washed up on shore, and in a bit of a daze (and much soggier) she waddled to swap out patrol with Celestia…

Celestia-drone hadn’t had much luck thinking of a way to get in to steal… whatever it was she was supposed to steal.

She hadn’t had much luck thinking in general, really. But she did see when her sister arrived, and looked up in vague confusion.

She didn’t remember Luna being that shiny. Or sloshy.

“I’m, mrf, back,” Luna said. “So… your turn to go and patrol.”

Celestia nodded. “Mrf,” she said, trotting out to go on patrol herself, not questioning the instruction because it was like an order and… it was easier than thinking of what to do herself.

As she waddled along, Celestia looked back and forth, then nearly ran into a pink poofy diaper.

The pony wearing the pink poofy diaper turned around, then sat down with a puff of foal powder. “Oh, good, you’re here! Auntie Celestia, I had some new diaper designs for you to try out – say you’ll try them on!”

“I’ll try them on,” Celestia agreed, automatically, the pacifier falling out of her mouth as she opened it for the first time since meeting Chrysalis, then blinked a few times as she tried to focus. “Cadance, what’s-”

“Oh, I’ve been thinking about making my own Butts team,” Princess Cadance replied. “The idea came to me in a dream… last night? Or maybe it was tonight? I’m not really sure…”

The pink princess shrugged her wings. “Anyway, the idea I had was, if you have the Wonderbutts and Luna has the Shadowbutts… I think that’s right?”

Celestia was sure there was something worrying about the Shadowbutts, but Cadance kept going. “Anyway, I tried to think what mine should be, and of course I’m the alicorn of love so it only seemed right to call them the Sissybutts. But I trust your opinion, so could you try this on and see how comfy it is?”

"Of course," Celestia said automatically before realizing she may have spoken too soon... but what was the worst that could happen?

So she waddled over to the Sissybutt uniform Cadance had laid out, and started with the big, poofy pink diaper. By now her padding was becoming absurdly thick and clumsy to move in, and the cute puffs of pink powder made her feel all subby princessy.

"The diaper is very soft and comfy... it makes me feel more like a princess," Celestia said with a blush hidden by her many uniforms as she moved onto the suit. The suit was an even more frilly and pink addition to her outfit, covered in cute ribbons and bows that made her want to wiggle shyly from just how over the top and cute it was. In fact, she did wiggle shyly, making her outfits and diapers crinkle and rustle adorably.

"Do you think it needs more frills and bows?" Cadance said in concern.

Celestia shook her head again. "Um, no, this one is already cute and plushy and soft enought I think..." She said as she put on the swirly mask, knowing the booties would make doing anything harder.

Immediately she was bombarded by more pink Subby, horny princessy swirls that made Celestia feel all flustered and even more squirmy... and when she added the booties, she blushed even more about the fact the hind legs were slippery, and kept her legs spread apart so every could see her humpable royal behind.

"I-I think this uniform will be perfectly cozy and comfy for the Sissybutts…" Celestia said, getting rather dazzled by the all the swirls in her many uniforms…

“Excellent!” Cadance replied. “Which means that, since you’re wearing a Sissybutt uniform, you must be one, yes?”

“...um,” Celestia said, confused, but the swirls on top of swirls on top of swirls were confusing her a lot.

“Yes,” Cadance went on. “You’re a Sissybutt, and Sissybutts do what I say! Because I’m the Princess who’s in charge of them.”

Celestia nodded, a bit confused, but Cadance seemed to know what she was talking about and good… drones?Wonderbutts?Sissybutts did what they were told.

“So, to make sure my Sissybutts are as good as they could possibly be, I order you to go and steal the diapers secrets from the vault! That way I’m sure that the Sissybutts will be as good as I need them to be!” Cadance finished.

“Yes, Ma’am!” Celestia said, saluting, then fell over onto her rump as she slipped on her slippery booties.

Trying to get upright led to her slipping over again before she finally got all four hooves under her, and she waddled off uncertainly.

And giggling.

“How come this isn’t… working?” Luna asked, then heard a giggle and turned quickly away from the vault.

Celestia was waddling-and-blushing her way towards her, and Luna tilted her head, because… something about her sister seemed different?

“Hmm,” she said, focusing on Celestia’s pink ruffly frilly padded outfit with bows and booties and a tutu and swirls and spirals perfectly normal outfit. “Did you… get your mane styled?”

“Yes!” Celestia replied, then giggled. “That’s what happened! I’m definitely not being all sneaky!”

She wiggled her rump, giggling again.

“Well… good!” Luna said. “Right, uh, my turn to go out patrolling…”

Luna was soon waddle sloshing her own way around the vault, trying to not go too far with how slow and waddly her gait had become.

She... quickly became confused when she found a second vault somewhat nearby their super secret vault... did everyone know about the super secret vault?!

Huffing in annoyance, Luna waddled up to the vault and opened up, surprised to see... stacks of diapers. And in a big, poofy diaper of her own, Diaper Lord Ember sat on her pampered throne, grinning at Luna.

"Ah! A worthy servant to join my cause! I needed someone to take the diapers treasures from the super secret vault for me, and you will do nicely." Ember said, her own padding so poofy she could hardly move. "I'm, erm, a bit stuck..."

"Um... I'm supposed to guard the diapers treasure..." Luna said, though she was also supposed to steal them, so perhaps stealing them some more wouldn't be bad?

"That's why you're the perfect agent!" Ember said as a plushy and somehow familiar Night-Fury outfit bounded out of the diaper pile and pounced on Luna, jaw opening to nom her down in a single move that somehow ended up with her suited up properly wearing it the right way around, and then diapering her up in an extra thick dragon diaper as the eyes became swirly...

"Now Pamp-Fury, waddle along and get my diapers treasure!" Ember demanded, waving her rattle staff of entrancing light around.

"Yes, Diaper Lord..." Luna nodded, waddling back towards the vault, more ditzy and dizzy then ever…

Poking at the vault with her bootied hoof, Celestia wondered how exactly she was supposed to open it and get at the contents. It had all sounded very simple when she’d been ordered to open it, by…

...whoever it was, again? She couldn’t remember…

...but whoever it was, right now it was impossible to see how to open it. And she wanted to make sure she did what she was told.

Even if, right now, she was mostly feeling blushy.

Then she heard a sound, and looked around to see a dragon Luna waddling towards her.

“Are you trying to mess with that, uh, hoard?” Luna asked, suspiciously.

“No!” Celestia replied. “It’s not a hoard, I mean, I’m not trying to mess with it, I mean, it’s not something I’m trying to mess with! What do you mean, hoard?”

“Oh, um… good question?” Luna answered. “I wouldn’t say hoard because I’m totally not a dragon and I don’t obey Diaper Lord Ember!”

She blushed a bit. “Obey Diaper Lord Ember… um, t-that is, isn’t it your turn to go out on patrol and let me try to work out how to open this?”

“Right!” Celestia replied. “I, uh… yeah, I’ll go out on patrol! But you’d better not open this! Not while I’m not around! I mean, um…”

She blushed, squeezing her diaper with her hind legs. “I mean, you’d better not open this, because…”

The sentence trailed off, and the two sisters looked awkwardly at one another.

“Patrol!” Celestia said, eventually, and waddled off – leaving Luna to poke awkwardly at the vault with her plush-dragon-pawed hoof.

Celestia waddled her sissy, poofy and powdery butt in the only other direction left to patrol, hoping that she could sneak back later to open Guard the vault for Queen Crinklesalis, Queen Pampdance Soggfire.

At least, she thought she was supposed to be doing something like that, involving diapers treasures and secrets. It was hard to remember with her feeling so dizzy and ditzy...

"Hey dweeb!" A familiar voice said, belonging to none other then Gilda the Griffon Poofin representative. And this Poofin looked extra regal in her pink princess dress and frilly pampers, and the grumpy look on her face told her she didn't exactly like being royal. Or pretty.

Even though, in Celestia's totally unbiased opinion, she pulled off the look.

"Oh, are you joining the Sissy butts too?" Celestia asked, which earned a snort from Gilda, who was about to retort when they were both distracted by a faint "Clunk" from the sky as the full moon mooning them pressed against the glass, giving them an extra distracting show for a few minutes seconds.

"No! I'm supposed to be finding someone who can get into a dumb super secret vault," Gilda said as the wind in the dreamscape shifted, all the pink poofy powder from their pamps rolling over her and making it harder to remember why she was annoyed as she felt dizzy and ditzy. "Say... I'm sure you'll do!" Gilda perked up, flying up in the air a bit in a fit of silly inspiration before butt slamming down on Celestia with a big POMPF of thick diapers and silly filly power that had both "princesses" giggling.

"Now I just need to dress you up... where did I get..." Gilda frowned, the idea of playing dress-up seeming rather dorkish before her gaze was drawn to the moon swaying across the sky, leaving Celestia squirming under her pamps for a few minutes seconds before Gilda remembered what she was supposed to be doing, swiftly dressing up Celestia into the pink, powdered pink griffon suit.

Celestia saw the swirly, shimmery goggles activate on the griffon suit, and giggled as she saw even more swirls fill her vision, every flap of the wings of the griffon suit spreading silly filly powder and making them all giggly and squirmy and soggy~

“Now, you… hee,” Gilda giggled, then shook her head, and tried to get a more serious expression.

Then she looked embarrassed, before remembering what was supposed to be going on and fixing Celestia with a glare.

“So, listen up!” she said. “I’m a bigger Poofin than you, which means I’m in charge!”

Celestia looked back at her suit, which certainly seemed bigger, then Gilda shook her head.

“No, I mean, I’m in charge!” she insisted. “I’m a more important one than you! I’m the head Poofin, okay! And that means you do what I say!”

Celestia was still confused, with swirly patterns going across her vision, and Gilda glanced around at the mooning moon again before pouncing on something.

“Aha!” she said, and put on a giant mascot griffin-head several times bigger than her own head, which had a hole for her actual head to look through and which had a pair of already-swirly eyes.

“There!” Gilda declared. “See? I’m the head Poofin! That’s why I’ve got such a big head!”

Now Celestia couldn’t argue, and it was a lot less confusing.

“So go and open that vault!” Gilda added. “I’m sure there must be something silly valuable in there! That’s an order from the head Poofin!”

Celestia giggled, nodding. “Got it!”

“Good!” Gilda said. “Now, go back there quick! I want those diapers that treasure!”

Celestia sat down on her rump, making a big poof of powder, and tried to salute, but it took her three tries with how much they were both giggling.

As the hypnotized princess pony changeling sissybutt poofin left, Gilda reached up to feel the big plushy head she was wearing, and frowned.

“Why am I wearing this stupid thing, anyway?” she asked, reaching up to pull it off, but the swirly eyes glowed.

Her forelegs relaxed, dropping away from the big plushy head, and Gilda Frillda giggled.

“Oh, of course!” she said. “Because I’m the silliest of all the Poofins, as their Princess!”

Once Celestia got back to the vault, she found it was a little crowded. It seemed the secret about the vault was well and truly gone, or all the other princesses had gotten bored of waiting and had come over to see how their agents were doing, and now there was a three way argument between Embutt, Soggystream and Soggy Secrets over who's agent Luna actually was, with Soggfire trying to chime in and argue Luna was a Wonderbutt, since clearly they hadn't broken into the vault.

"She's clearly a Wonderbutt! My vault is still locked up as tight as her diapers!" Soggfire declared, huffing needily as the royals patted her bottom and kept layering cute diapers on her and Soggy Secret's butts, arguing over which patterns were better.

"I'm a Wonderbutt!" Luna agreed.

"No, she's a Shadowbutt! She's got on the Shadowbutt uniform and everything!" Soggy Secrets said as Embutt layered another diaper onto Soggfire's rump, only for Soggystream to add one to his rump too.

"I'm a Shadowbutt!" Luna agreed.

"No, She's Seapony! She can swim in water!" Soggystream said, patting Luna's extra soggy diapers. "And she's soggy like one too!"

"I'm a Seapony!" Luna agreed.

"No, she's a dragon looking for treasure! She loves shiny, swirly things, and she flies!" Embutt declared as Soggfire and Soggy Secrets were layered up again.

"I'm a dragon!" Luna agreed, and the argument kept going around and around in swirly, silly, soggy circles... and when Celestia waddled up, the debate began anew between Soggfire, Queen Crinklesalis, Queen Pampdance and Princess Frilla.

"Well, why don't we just open the vault and see what the Diapers secrets are?" Soggfire declared, getting tired of trying to have two arguments at the same time. "Even I can't get into the vault, so we'll have to put our heads together..."

Luckily, they would get a helping hand: they'd been so distracted they didn't notice the freshly changed, still swaying and shaking moon pamp coming down from the sky...

It sat on all of them and the vault with a massive POOOOMPFFF of powder and crinkles, filling the air with more pink silly filly powder as they were preeeeeesed into the vault door, forced to see the big, swirly pamp in their faces.

Nightwear did have the best diapers after all~

After smoooshing and squuuuuishing them for a bit to help press out those big girl thoughts, the vault door suddenly opened, spilling them all into the inside of the vault…

Author's Note

There seems to be a lot more in the way of Princesses here than before, including at least one honorary one.

Not a sign of things to come, I think.
