Shiny vs Sunny

Both Shining Armor and Sunburst were now forced to play with the other foals until Cadence could come to pick them up. They indulged in a game of catch with a ball covered in foal drool. Shining sighed as he tossed it to Sunburst and grumbled. “So ya weady to be babied? Because if ya taught being a toddler was bad, wait until Cady gets hewe and sees us.”

Sunburst eyed the white-coated foal and threw the ball back at Shining as he retorted. “Weww I don’t tink this wiww be so bad, she gonna wet us pway in ta playpen with ya daughters. Besides, I’m sure we didn’t wose our potty wraining competewy.”

The little white colt just sighed and shook his head as he threw the ball back at Sunburst. “Well I hate to bweak this to ya, but Cady is most likely gonna keep us in diapees fow a while. And not just ‘cause she’ww punish us for steawing the potions.”

Sunburst rolled his eyes and growled, “I not going to stay as a foaw! Cady wouldn’t do tat!”

The foal prince scoffed. “Ten ya dun know my wife weally well. Ya weally tink she was okay with us tuwning into toddlers just because we can hewp teach Fwuwwy Heawt and Fizzwepop how to potty twain? She’s gots what they call ‘Mommy fever.’ and tat’s not even a wowd!”

Sunburst gulped as he whimpered. “Bu...but didn’t she wose mommy fevew after Fwurry was bown?”

Shining Armor gave a small nod. “She did, until Fizzwepop came into owa lives. Now she’s in mommy fevew ovewlowd. And I tink she’s gonna be that way tiw Fizzwepop’s in pweschool.”

Sunburst gulped as he looked down at the diaper, remembering how Cadence had been during her first bout of mommy fever. “I evew told ya how one time Flurry was crying and both me and Cadence woke up to calm her down? After she put ta baby ta bed she wawked me back to bed and tucked me in.”

Shining rolled his eyes. “Oh ya gots it easy. While she was pwegnant she would call me ‘Shiny’ and would even ask if I needed to go potty during meetings. It was so embawwassing!”

Two of the other foals burst into laughter as one babbled. “Oh yeah? Owa mommy stiw gots mommy fevew. She diapees up the class sometimes.”

The other colt nodded and as he looked down at the class, who were all watching with awe at the foals (who imagined the entire kindergarten class padded up) and they burst into laughter.

Just then, Cadence burst through the doors and turned towards the two colts as Shining sighed and laid down. “Get weady, Sunbuwst! She’s gonna wana punish ya by giving ya kisses.”

Sunburst eeped but was instantly swept up into her hooves along with Shining Armor as Cadence cooed. ”Oh you naughty foals, what am I gonna do with you?” She looked over them and sighed, ”I should be quite furious, but how can I be when you’re two chubby wubby foals?!”

The kindergarten teacher approached Princess Cadence and cooed. “Oh, you had two little colts as well? Forgive me, I didn’t know.”

Cadence turned around with a smirk and waved a hoof. “Oh, they’re not my foals. This is actually my husband, Shining Armor, and my elder daughter’s crystaller, Sunburst. They were regressed accidentally by my daughters. Now it seems these two drank a regression potion without my knowledge, and this is the result. Still, I suppose it could’ve been worse.”

The teacher gasped and whispered. “Oh dear, that sounds like a lot of work!”

Cadence looked down at the quivering foals. “Oh, I don’t think I’ll mind having two more foals. I’ll just tell everypony, Shining and Sunburst are on vacation. I’ve already come up with names for them while they’re toddlers, in case anypony asks.”

Sunburst placed his hooves over his diaper and whimpered as Shining just sighed and plopped down on his diaper. “Told ya, Sunny, she gots mommy fevew and it’s weawwy bad.”

The two colts were taken home and brought to Flurry’s and Fizzlepop’s nursery in their thick diapers. Rebecca Pie scanned them with her magic.

Cadence asked the mare. “So, Rebecca? Did they lose all their potty training? Are they going to have start all over again?”

Rebecca shook her head. “No, my potions are safe and aren’t volatile. Since I can’t make potty training potions, I also can’t make anything that undoes it. What your daughters did was a very advanced age spell, and when it’s done improperly it can lead to things like a lack of control over bodily functions. I can turn them back into toddlers if you want though. You said you gave them each one drop of the potion?”

But Cadence replied. “Actually, I was thinking that for their punishment they will be foals for a weekend. I’ll let them use the potty of course, but they're staying in thick, cute diapers so they have to ask me first. I won’t risk any mishaps like what happened at the museum.”

Sunburst turned around and groaned. “Ya wight, Shiny, she gots ta mommy fevew and she gots it supew bad!”

Shining (who was now being levitated over to the other foals alongside Sunburst) had a deadpan expression and he just replied “Eeyup!”, just as he’d often heard Big Macintosh speak.

Sunburst squealed as Fizzlepop was prodding his diaper with a curious hoof. “Hey, you gots a good bwand of diapee on ya. Why is it so thick?”

With a blush growing on his face Sunburst stammered. “I d...du...dun know. tat cwazy kindegawten teachew put them on us.”

Fizzlepop looked down at her blue diaper and groaned, “I wish Cady stopped getting these diapees. I mean, tey cute but they dun wowk too well.”

Flurry Heart fluttered over and gave a confirming nod. “Yeah, I agwee. I wanna get ta diapees Auntie Tia and Wuwu got fow us.”

Shining (who was still being held by the magic) just grumbled. “Well, Cady wikes tose diapees because tey easy to cwean.”

Flurry crawled over and asked. ”Can ya get us ta one ya got on, pwease?! They wook supew comfy.”

Shining (now upside down due to his daughter’s magic) squealed. “Alwight, alwight, I pwomice! Now pwease put me down!”

Flurry obeyed and slowly let Shining plop onto the ground with his diaper, causing Cadence to chuckle. “What was that all about, Shining?”

Shining just rubbed his rump and grumbled, “Flurry and Fizzlepop want bettew diapees is all. Tink you can get tem ones wike what Sunbuwst and I awe weawing?”

Cadence grinned. “Well I’ll think about it, but I also have a surprise for you all! Two very special ponies are coming to see you.”

At that both Princess Celestia and Princess Luna burst through the doors with big smiles on their faces and diaper bags strapped around them.

Both colts just gulped and whimpered awaiting for the oncoming cuddling from the princesses.

The princesses held the two little colts together pinching and cooing at them. Celestia smirked while lifting Shining up with her magic. “I can’t believe this little foal used to be my Captain of the Royal Guard. I’m afraid I don’t have any diapered regiments for my royal guards right now, though perhaps I could look into a peewee one for the little ones of guard families.”

Luna lifted Sunburst with her magic and patted the diapered rump. “Oh, I can’t believe this little colt once helped to save the entire Crystal Empire. How on earth could they be such adorable little heroes now?”

Shining, now getting fed up at constantly being babied exclaimed. “Pwincess Cewestia, ya know tis isn’t the first time you saw me in diapees!”

The princess of the sun smirked. “Oh yes, that’s true. I’d almost forgotten. You caught me while I was thinking about babies and I couldn't help but put a cute diaper on your butt. Fortunately I quickly took off it and we both agreed not to speak about it, until now.” She plopped Shining into her lap and stuck a bottle in his mouth as Luna did the same to Sunburst.

Celestia then turned around and cooed. “So, Luna what do you think we should do with these two? Maybe we should to go that foal’s birthday party with these cuties?”

Cadence grinned. “Sounds like a fantastic idea. Just make sure to keep an eye on them, they’re little trouble makers if I ever saw them.”

Luna grinned. “Well, since nopony can know who these two really are and it’ll look weird for them to be cared for by the princess of Equestria, I think I have an idea on how we can go to the party without attracting attention,” She lit her horn and let tendrils of magic wrap around her body as she slowly transformed herself. The mare's body soon became that of a dark blue crystal pony with a light blue mane, and dark velvety eyes. The mare tossed her mane and cooed. “Meet Clear Night.”

Celestia laughed as she commented. “Well, well, Luna. You look quite flattering as a crystal pony if I do so myself. Now it's my turn!” And lighting up her horn, she turned herself into a white coated crystal pony as she smirked. “Meet Sunshine.”

The disguised princesses turned to the two little foals and both groaned as they were picked up and were placed into strollers.Then they were pushed out into the streets of the Crystal Empire.

“Have a good time!” Cadence waved a hoof.

The two regressed colts soon found themselves at a birthday party with mothers and their foals playing about in the house. But the sounds were mostly foalish babbling and playing as Shining and Sunburst were seated in the laps of both Celestia and Luna (who were chatting with the other mothers).

The colts had bottles in their mouths and were kicking about in sodden diapers, unable to ask even to go potty with bottles full of formula, not that they were sure they’d even be allowed to without Cadence.

Just then they happened to look over and saw their friends Crystal Shard and Crystal Clear! Both were chasing each other until they spotted the foals as they came over. Both Shining and Sunburst whimpered as the two came up, and Crystal Shard asked. “Oh are ya Sunny Day and Cwoudy Day?!”

They whimpered as Celestia turned and explained. “Yes they are. They had a little bit of a magical incident regressing them. They’ll be fixed soon enough. But for now, they’re staying as babies as punishment!”

The two giggled as Crystal Clear looked at Sunburst and cooed. “Oh, he’s even cuter as a baby. Can we pway with tem?”

The two disguised princesses gave a nod of approval and after changing Shining and Sunburst allowed the two foals to be taken to the playpen. “Play nice, you two.” Luna instructed.

Shining and Sunburst groaned as Crystal Shard stood over Shining. “Wooks wike I owdew then ya now. Ya know what tat means, wight?” He then took Shining and dressed him in a purple dragon costume that looked a lot like Spike as the young colt explained. “Your ta big meanie dragon, and I ta gweat knight twying ta save ta princess!”

Crystal Shard raised a foam sword and whacked at Shining, who got up on his hind legs and growled, “I am a big, scawy dwagon! Grrr! I wiww eat you!” He waddled forward with his cute little tail wiggling and hooves in the air. He was glad the costume covered his face, no one could see him blush.

Crystal Shad took some jabs with his foam sword into the pudgy belly of Shining, the purple dragon. The little colt dramatically fell over, then plopped onto his diaper with a face of confusion as he squeaked and pressed his hooves over his diaper. Suddenly, he squealed as a hiss echoed throughout the room. “Oh no! I completely forgot about the formula I drank!” He thought, ashamed that it had never crossed his mind to ask to go potty.

All the mothers just dawwed at the adorable scene as Crystal Shard raised his foam sword in triumph. “I swayed ta wittwe dwagon and made him pee pee his diapee! I am victowius!”

Shining pouted as he charged and tackled the crystal colt! Crystal Shard squeaked in horror as his diapered front turned a deep yellow. The colt’s mother cooed. “Oh my, Crystal Shard. Looks like the little dragon made you pee too. Guess you were having too much fun, soggy pants.”

Crystal Shard roared as he stood up, attacked Shining, and they continued their cute struggle.

Meanwhile, Crystal Clear had dressed up Sunburst into old fashioned foal clothes with a frilly blue foal bonnet, an onesie with a lovely little white blouse with blue frills, and his diaper poking out through the fabric.

The colt groaned while trying to walk, but the fabric and his peripheral vision made him fall down and plop onto his rump.

The other mothers dawwed at the adorable scene as Crystal Clear explained. “Tese awe foaw cwothes from wha my mommy cawws ta cwassical era. Tey designed for comfowt.”

Sunburst pouted and crossed his forelegs as he. grumbled. “Tis is so stupid! Why would any foal wear tese stupid cwothes?!”

The filly cooed. “I towd ya, tey were designed for comfowt and had a cwassy wook.”

Sunburst got up with a pout and shouted. “Weww, I not an owd foaw! I dun need these siwwy cwothes!”

Crystal Clear pouted as she growled. “Ya shouwd wespect ta past, Sunny! Those cwothes were fwom my gweat gwandma when she was my age!”

Sunburst squeaked out in horror. “Tese awe fiwwy cwothes!” He started trying to pull them off his body, despite the booming laughter coming from the mothers. He looked up, blushing as Celestia picked him up with her magic and nuzzled him. ”Oh, you just look adorable in that cute little outfit. Like a doll!”

Sunburst kicked and fussed about before a blue pacifier with a sun for a mouth guard was plopped into his mouth. The colt groaned and reluctantly accepted it as it bobbed up and down in his mouth. The mothers all dawwed and took pictures, while all Sunburst could do was whimper and suckle his pacifier nervously.

Shining Armor finally was able to get up from his struggle with Crystal Shard and turned to see Sunburst getting all the attention from the mares.

Luna then picked up Shining with her magic and cooed. “Oh, what’s wrong? Do you want some attention too, cute little Spikey Wikey?”

Shining shook his head and tried to shout. “No! I fine! I just wana pway!” But his kicking about made his diaper rustle and his cute little tail wiggle, making some of the mares come over to him. Shining groaned and squealed as a pacifier with a moon mouth guard was placed into his mouth, before he was picked up by Luna.

“Let’s get you changed, Spikey Wikey, then you can play some more.” Luna teased. All Shining could do was fuss and kick about in protest. At least the change itself was quick, Luna effortlessly removed and balled up the soaked diaper for disposal, wiped Shining down thoroughly, and placed him in a new diaper with several helpings of fresh foal powder.

When Shining returned he could already see several of the mothers taking turns pinching Sunburst’s cheeks and cooing over him, and the foalified prince resigned himself to a fate he saw he was powerless to stop.

“Hey, Cwoudy,” Crystal Shard spoke up during a brief lull on the cooing and fawning. “When ya tuwn back to nomaw next week, ya gonna be attending the pweschoow again?”

Shining nodded. “Yeah, why ya ask?”

Crystal Shard whispered. “‘Cause thew’s someting about ta potty I wanna ask ya about. I may need ya hewp on it.”

“I’ll tink about it, Cwystaw Shawd,” Shining answered. “I gots to suwvive mommy fewew fiwst!”
