Shining Armor awoke in the same playpen from a few hours before. He looked around to see many of the royal guards surrounding his parents as they seemed to be interested in some book his mother had in her hooves. She was babbling on about a birthmark on his bottom or something. He then slowly got up, not noticing his diaper was quite soggy with the padding stained yellow and the patterns fading. Shining didn’t seem to care as he waddled over with an angry look on his face. “Hey, wha gives?! Are ya wooking at my photo awbum?”
The guards all looked up as Celestia squealed, bouncing on her padded bottom. “Ya weawwy have a famous diapee dance, and ya nevew towd us?!”
Luna snickered as she shook her diaper about, making it crinkle and have powder puff out and shouted! “Wook at me go! Is tis how ya did it?”
Shining rolled his eyes, seeing Luna shaking her rump about. The princess was giggling and seemed to be having a good time.
But the embarrassed colt whined. “No, stop tis! Mom, why ya showing my embeawssing baby pictures wook?! I dun need ya embawassing me! I a baby aweady!”
Fluttershy hopped over with a smug grin on her face as she went about picking the padded prince up and cooing. “Oh yes you are! And your diaper is quite soggy too! You need a change.”
“No, stop tis! I not gonna be tweated wike tis!” The little colt whined and kicked frantically as he was placed on a nearby changing table, and his diaper was changed in a matter of seconds. “Ugh, sewiouswy?! Peeing my diapee again? I had enough embewwasment fow one day!”
“Well, cutie, get used to it. You think I was going to leave you in a soggy diaper? I couldn’t let you get a rash, you wouldn’t be able to have a wedding or wage battles with one. You’d be too distracted by the feeling.” Fluttershy scolded and plopped the freshly changed foal back into the playpen with a poof of foal powder.
Shining groaned as he began to shake his rump about, trying to get the excess powder out. “I hate it when someponies do tis!"
All the other foals nearby were now coming over to watch the famous diaper dance in action. They cooed and awwed over the adorable dance. The colt continued to do it despite the growing audience, and it was entirely too late when he saw that all his royal guards were snickering, and he plopped down on his padding with a blush on his face. “Stop tat, ya aww being supew wude! Ya gonna gets time-outs fow tis!"
Twilight Velvet just giggled as she shook her own padded rump. “Tis is quite fun! No wonder ya wiked doing tis aww ta time when ya was a baby.”
Nightlight snickered and shook his padded rump about with powder puffing out. “Yeah, tis is fun! Come on, wets aww do ta diapee dance!"
The foals all soon joined in shaking their padded rumps, making the entire playpen fill up with foal powder.
Shining coughed and gagged as he waddled out from the clouds of foal powder and plopped into the corner. “Ugh! My pawents awe cwazy! Why ta awways gotta do tis?”
The young teal coated collt from earlier giggled as he waddled over. “Hey, wooks wike ya awake.”
Shining stomped about and whined, “Yeah, I awake and angwy. My pawents awe being supew annoying and embeawwasin me again!"
The teal coated pegasus waddled over. “Sowie. If anything though, ya pawents awen’t as cwazy as my mommy. She can be vewy mean.”
Shining eyed the colt and curiously asked. “Who is ya mommy, anyway?"
The pegasus blushed, scrunching his pampers between his legs as he whimpered. “Oh, she...uh...she a bug cowwectow? Anyways, tats not impowant,” And he quickly changed the subject. “Did ya wememba anything I told ya befowe?”
“No, not weawwy, so what ya saying on how we stop ta changelings?” Shining asked.
The teal pegasus sighed. “Otay, aww we need is some ponies to daww and mothew them so tey feast on tat wove. We need Fwuttewshy fow tat.”
Shining blushed and explained. “Weawwy? We need a awmy of mommies and nannies?"
The teal pegasus shook his head. “Yes, bu we dun have the time ta do tat so we needs Fwuttewshy since she so mothewwy. Anyways we can use tat to owa advantage wike with ya mom since she was a mommy, and ya sistew Twiwight and Pinkie cause tey cows and have woads of wuv."
Shining smiled. “So we can use tem to hewp distwact ta change-” But then the prince paused and eyed the suspicious colt.”Wait...how couwd ya know about Twiwy and hew fwiend tuwning into cows? Ya’d have to be at the wedding when evewypony got twansfowmed by the chaos bomb.”
The little colt plopped on his pampers, puffing out some more foal powder. “Otay, wook...I actuawwy a changeling, awight? But I not a bad changewing...my name is Thowax. I wanna hewp ya.”
Shining waddled over and shook the colt. “How I know ya not spying on us fow Chwysawis?”
The teal colt crossed his hooves and responded. “Wook, why wouwd I tewws ya I a changewing if I was a spy? Why wouwd I give mysewf away?”
Shining Armor plopped on his diaper with foal powder puffing outwards as he sighed. “Guess ya make a good point. Besides, we need to deaw with anothew pwobwem fiwst.”
“Oh yeah, what’s tat? The teal pegasus asked with a smirk on his face, having a feeling about what was going to happen next.
“We needs to stop my pawents fwom embewasin me anymowe!” Shining whined, pointing a hoof at his mom and dad who were still shaking their pampered rumps.
But the teal colt sighed and shook his head. “Sowie, ya on ya own fow tat one. I not gonna hewp ya.”
Shining Armor rolled his eyes, seeing his parents continue to dance about. “Ya two awen’t even doing it wight! Tat’s not how ta diapee dance wowks!” The little colt then waddled over and started to shake his rump around. “See! Ya gots to shake it wight so ta foaw powdew comes out, tats ta weason fow it!”
The little colt continued to waddle and shake his rump in an adorable fashion. He didn’t stop until Fluttershy bounced over and cooed. “Sorry to interrupt your adorable little dance, but we need to get you all fed.”
Fluttershy then started shoving all the foals into her pouch, and then bounced off to the kitchen to feed her new charges. She plopped them down into dozens of highchairs as she explained. “I went by the foalstore where the changelings attacked us while you were all napping. Luckily, the store owner was happy enough to sell us highchairs and other things in bulk. With the foal pandemic almost over they had a lot of excess supplies they needed to get rid of."
She then placed Shining down, who sighed as she took out a giant bowl of foal food (which was Mashed Peas) and began to shove the green mush into each of the foals’ mouths. It was cute as she fed them one by one, and Shining had to wait awhile before it was his turn to gobble down some of mush.
Luckily Fluttershy had dozens of foal bottles filled with formula, and the motherly kangaroo went about plopping the bottles into her charges’ mouths.
Shining sighed, burping and blushing as he spat up a little, then he saw his parents waddling down the halls with a horde of foalfied guards. He eyed them as he plopped down from his highchair and followed them through the halls.
The colt was quite surprised at how big the hallway was, now full of baby pictures of him and Twilight, and he sighed. “I can’t bewieve I actuawwy waddwing thwough my owd house in pampews. If I had memowies fwom me as a baby tis wouwd be De Ja Vu.”
Shining waddled further, passing by the bathroom as he saw the door was open. He waddled inside, feeling a paint twinge in his bladder from all the milk he’d drank. “I don’t wanna pee my pampers again,” He thought to himself as he approached the toilet. “I bet if I actually used the potty, that would show everypony that I’m not a baby, and they could stop treating me as such.”
Yet in order to even get up on the seat, Shining had to stand on his tip hooves and jump up. As he balanced precariously on the slippery seat, he fiddled around with the tabs holding up his diaper. Doing so made it hard for him to concentrate on holding back his bladder, and focusing on that made removing the tabs more difficult. “Urgh!” The little colt groaned as his face turned red and beads of sweat began to pour down his face. He was forced to switch from his hooves to his teeth, and only barely managed to undo the tabs enough to wiggle them halfway down.
Sighing with relief, Shining slowly sat down on the seat and let his bladder empty itself. He was surprised though when he heard what sounded like giggling and clapping. Looking down from the toilet seat, he saw his parents along with several of the guards from earlier were all watching him.
Eeping, the little colt swished his tail! “Hey! Wha ya aww doing hewe?!”
Twilight Velvet just giggled. “Ya weft the doow open, siwwy. And ya so cute when ya going potty.”
“Need any hewp, son?” Night Light offered. “Ya dun want the potty monster to eat ya.”
But Shining just groaned and hopped down from the toilet, using some toilet paper to clean up. He didn’t bother to flush, and only barely washed his hooves. “I dun need hewp I not scawed of ta potty monstew!” Then he blinked and groaned. “Wait, thewe’s no such ting!”
Velvet only giggled. “Is okay. Just wet youw foawish mind take ovew. I gots someting I wants to show ya.”
Following his parents, Shining continued to his old bedroom and gasped, seeing that it had been completely re-decorated into a foal’s bedroom! There was a giant play rug full of little animals in primary colors, his old crib had been set up with some old teddy bears, a creaky mobile and a wardrobe full of foalish outfits.
Shining pouted and whined. “Seriouswy!? Ya two aw gonna tweat me wike a foaw, even aftew wha I just did?!”
Nightlight blushed as he slowly walked backwards. “Dun wook at me! Tis is aww ya mothew’s idea when she heawd about ta foaw wedding!”
Twilight Velvet rolled her eyes. “Why wouwd I not? Is evewy mothew’s dweam to have theiw kids back. And mine’s back as a baby! I owny wish Twiwy got to be a baby again too.”
Shining scoffed, seeing all the guards going through his old baby stuff. The colt then spotted said guards going through his old toys, including his childhood snuggle buddy in Brutus Force. He waddled over and shouted! “Hey! Dun touch my toys, tey speciaw! And Butwus Fowce is mowe tan speciaw, he my bestest fwiend!” Because of this he started prying his plushies from their hooves. “Tis is aww pwivate, and ya dun have pewmission to touch any of this! Now get out of hewe, tats an owdew! And ya can’t wefuse an owdew fwom ya captain! If ya do, I make ya cwean the watwines.”
Soon all the other guards began crying and wailing, making Fluttershy bounce over and scold Shining. “That was quite naughty, Shining. Apologize and share your toys like a good little pony. I’ll make sure they don’t play too rough with them.”
The colt grumbled and snapped. "I’m stiww ta captain of the guawd! Tey gots ta do what I say, ow I gonna punish tem!"
"No, you're a foal now, and you have to listen to me because I'm your caretaker,” Fluttershy demanded with a stern glare. “You share your toys and apologize, or you’re going into time out!" The kangaroo scolded with her paws crossed over her chest. “That means you’ll lose all your big pony privileges.”
Shining threw a small tantrum but not wanting to risk time out reluctantly did as was asked of him, hoofing off the toys one by one. Soon the crying stopped, replaced with joyful coos from his fellow guards as he waddled away in annoyance.
Thorax came over with a blush, still in his pegasus disguise.. “Hey, it couwd’ve been wowse. At weast ya have a woving famiway. My mommy was anyting but woving.”
Shining whined. “Shut it, Thowax! I wants to be awone! I dun know if I can fuwwy twust ya yet, ‘cause ya a changewing too. If ya wucky though, ya won’t get punished wike the west of tem wiww when tis is ovew.”
Thorax sighed, seeing that Shining was in no mood to talk. He then turned to see Bucket Bridle, Cannon Feather, and Brightwing were also enjoying playing with the regressed stallion’s stuff. He slowly came over to Brightwing and said to him. “Hey um...we need to hewp get ya new daddy onboawd and weady to twust me in hewwping save Cantewot.”
Brightwing sighed, seeing his new daddy was kind of being grumpy and grumbled, “Wight he can be vewy stubbown, but I can hewp him! I was a big pony once too and know how aww tis baby stuff can be vewy embewassin. He hewped me, so now is my tuwn to hewp him.”
The little colt waddled after his dad as Thorax shook his head. “I just hope tey weady because even as a baby, Chwyasiws is not someone you wanna mess with. I just hope she not causing too much twoubwe at the castwe.”
Chrysalis was sitting across from Princess Cadence in her little jail (which consisted largely of changeling goo) playing a game of Go Fish with her prisoner. Both were wearing Rarity style diapers, and Chrysalis's padding was clearly soaked in urine.
The princess looked up from her cards not really being able to tell what the numbers were, glaring at the regressed queen as asked, “So...even if ya captuwe ta pwincesses and my husband, how wiww ya take ovew Equestiwa with ya being a baby? Awso, ya gots a thwee?"
Chrysalis looked up from her hand and whined, “I dun know! My awmy and I wasn’t supposed to town into foaws! This takeovew was supposed to be fwawwess! Also, I dun have a thwee, I fowgots what thwee was!"
Cadence snickered and eyed the queen. “Um, I dun mean to be wude, ya pwan was good and aww, using owa wedding as a covew to takeovew ta kingdom. But ya fowgot tat six ponies wewe hewe tat pwobabwy would’ve used ta Ewwments of Hawmony to kick ya butts!” Then she huffed. “Ya got any twos?"
Chrysalis pouted and eyed her captive. “Maybe. But ten maybe I wouwd’ve just captwed tem too! Besides, I dun got twos. Ya got any fives?"
Cadence shrugged. “Maybe, but tat wouwd've been quite difficuwt anyways, just saying. And I fowgot which one was five."
The queen of the changelings pouted and crossed her hooves across her chest. “Give me a break, considering ya awso was captured! I’ww just find a way to tuwn back into a big changeling and weave ta west of ya as babies, how about tat?!”
The princess of love rolled her eyes. “Yeah, good luck with that. I doubt ya can change any of Discowd’s cuwses. Heck my hubby and I been foaws fow a month and Twilight, ta best magiciaw usew in Equestwia twied evewyting to change us back.”
Chrysalis threw her cards down since both her and Cadence had forgotten how to properly count anyways and snapped. “Fine! Maybe I just have tis Discowd change evewypony into babies and ruwe tem aww!” She laughed wickedly as she said this.
Cadence snickered. “Good wuck changing ta diapees of evewypony in Equestwia, not incwuding ya awmy of changewings and ya own.”
The changeling queen looked down at her soggy diaper as Cadence brought out some clean pampers, along with some foal powder and wipes. “I tink tat tis is why ya decided to pway go Fish, sos ya’d tink I wouwdn’t notice ya went pee pee. Come on! I maybe ya pwisonew, but I pwetty good at changing diapees now, even as a foaw.”
Chrysalis reluctantly laid down as Cadence went to work, cleaning the regressed changel’s rump and afterward taping her into a fresh diaper. “Thewe. See, no big deaw.”
The changeling queen got up and whined, shaking her diaper about and making it puff out. “Ugh! Why did ya put so much foaw powder in?!”
Cadence giggled. “Just ta see ya do Shining’s famous diapee dance! Ya so cute in pampers!”
Chrysalis's face turned red as she felt a load of love from Cadence get absorbed into her, but it felt so weird to get love this way and turned about. “No, I not cute!”
The princess of love was feeling a bit woozy but still giggled, “Yeah ya awe, especiawwy with tose poofy cheeks and how ya got tat chubby bewwy!”
Chrysalis poked her belly. “Is just foaw fat! It’ww go away when this stupid speww is ovew! I was quite thin as a big changewing!”
The princess of love rolled her eyes. “Ya being so siwwy! Besides, ya can weawwy wowk tat diapee."
Chryaslis waddled about in her new diaper and showed it off. "Weawwy, it doesn't make my butt wook big?"
Cadence blushed as she felt more love being absorbed into Chrysalis. "Y...yeah! Ya ta cutest foaw eva! Tat diapee makes ya wawk so wobbwy and cute!" Then she exclaimed. "Come on, ya need mowe miwkies! Twiwight!”
The Twilight cow looked over with a smile. “Hey Cadence and Chrysalis, you two need some milk?” She walked over, shaking her udders about. "Go on, I’ve got plenty of milk! I'm sure I can never actually run out." She turned around, thrusting her udders out to the foals.
Cadence instantly waddled over to suckle, while Chrysalis was unsure at first but heard her tummy rumble and sighed, “Fine, one wittwe suckwe and tats it! I dun wanna get fat!” She latched onto one of Twilight’s udders and began to suckle down the creamy milk, unable to let go.
Cadence was snickering seeing the queen suckling milk out like a foal. The queen of the changelings herself was blushing, feeling embarrassed and secretly liking this feeling and hoping to be a foal for just a little bit longer.
