Celestia was fixing Sombra’s mane and tail brushing them slowly and humming a tune while doing it. Sombra starred into a mirror at his poofy blue suit and his poofy blue diaper with little duckies decorating the front of it. He sniffled a bit, knowing that tonight would be the last night that he’d be living in the palace. He looked at Celestia, whose eyes were also wet, and he asked, “Mama, ya thin tha me goin to Ponyviwe is a good idea?”
Celestia paused in her brushing, “Yes it is,” she assured Sombra. “Everything is going to be fine. I promise I’ll still come to see you when I can.”
Sombra wiped the tears from his eyes, “Ya, bu itll be gweat to see my fwiends again.”
Celestia then placed the foal bonnet around his mane pulling out the white frills and tieing it around his neck. “You know something?” she asked the former king.
“Wha Mama?” Sombra asked as he looked up.
Celestia nuzzled him and said, “When you learn to write, we can send each other letters everyday. Then we’ll be in touch all the time.”
Sombra nuzzled her back and replied, “I pwomice I will wite ya evewy day.”
“Now let’s get you downstairs, your friends should be arriving soon.” Celestia told Sombra then placed him on her back then as she strode through her room. The next thing they saw Prince Blueblood coming down the hall in his best suit. Sombra looked at him with intent eyes and then crawled off Celestia’s back. he crawled over and hugged Prince Blueblood’s left hind leg.
Blueblood looked down at his legs and shouted, “Cur! Get off!” Sombra hugged harder as he shouted, “Celestia get your foal off me!”
“Come on Blueblood, this is his last night here,” Celestia replied. “He just wants to say goodbye.”
Blueblood looked down as Sombra whispered, “Bye Bwuey, I’m sowie fow makin messies aww the time.”
“Oh, I guess I can forgive you,” Blueblood told Sombra, knowing that Celestia would surely punish him if he was mean to Sombra. “Now, go back to Celestia. This castle certainly won’t be the same without you.” He told Sombra then galloped off.
“Ya think I’ll be fwiend with Bwuebwood some day?” Sombra asked, as he was placed onto Celestia’s back.
Celestia laughed, “Maybe, but with Blueblood who knows for sure?”
Sombra hugged her mane then he looked down the stairs as he saw Luna standing near the front doors.
Luna dawwed at Sombra’s appearance, “Oh Tia, he’s adorable,” she informed her elder sister. “I can’t wait to see how the rest of his friends look.” She turned and opened the doors waiting for the first guests to arrive.
Sombra’s friends arrived soon afterward. On Applejack’s back Chrysalis wore a pink petticoat with a pink bonnet hugging her face. Underneath was a puffy white diaper with little red apples decorating it. Discord sat on Fluttershy’s back, he wore a light green onesie with bunnies decorating it and a button flap. His white diaper was clearly visible underneath with pink frills coming out of his legs holes. Pinkie Pie came out with Nightmare Moon in a big puffy pink princess dress with a pink cone hat. But she was the only one that wore a pink pair of pull ups. They all bowed to the princesses when they got near the entrance.
Celestia replied to them all, “It’s okay, you can rise.” And so they did.
Luna was just smiling looking at the foals. Then she turned to Applejack, Fluttershy and Pinkie Pie and asked, “Is it too much to ask? I promised to show them all something tonight before the party starts. It was a surprise I didn’t get to show them on the night they were almost foalnapped.”
“Want to go with Auntie Luna for a while?” Fluttershy asked Discord.
Discord laughed and replied, “Yeah! I wan see the supwise.”
Chrysalis was nudged by Applejack, “Wha ya say? Ya wanna hang with Luna for a while?”
Chrysalis laughed, “Eyyup,” she said, mimicking her uncle Big Mac’s famous catchphrase. “I wana see what the supwise is.”
Menawhile Pinkie bounced up to Luna and said, “Alright Moony, Be a good girl for Auntie Luna. No disappearing.”
“I wun, I’ll be good.” Nightmare Moon promised,
Luna then took the foals on her back and flew to the top of the palace. She had the foals all sit on the roof, then she asked “Alright you four, ready for your surprise?” The four all giggled and clapped as she flew into the air. They all looked up as Luna raised the moon, the four foals were wide eyed as they saw Luna raise the moon to the top and shine on the foals! Luna then came down and asked, “How was that?”
They all clapped and Chrysalis was the first to shout, “Woona, that was amazing!”
They all started climbing ontop of Luna causing her to laugh, as she then she fell onto the roof with the foals hugging her. She hugged them back and laid there for a few minutes, smiling (while holding them in her magic so they wouldn’t slide off the roof) “I’m going to miss you all, you especially Sombra,” she told the four. Then, placing them on her back shetold, “Alright, time for the party!”
Inside the palace, the party was ramping up with the ponies all dancing or talking. When Luna strode through with the foals on her back, everypony looked up and dawwed at the four foals. Some clapped and cheered shouting “Good job!”or ”Thank you for saving Ponyville.” having been informed of the events of the shadowy mare.
Discord laughed and waved his claws in the air trying to take in the glory by standing up and plopping onto Luna’s back. Sombra blushed and hid behind Nightmare Moon. Nightmare Moon looked up and giggled, waving to evrypony gathered. Chrysalis was the most nervous as she hid behind Sombra.
Suddenly, Discord saw the dancing ponies and asked, “Auntie Wuna, can I go dance!”
Nightmare Moon bounced on Luna then shouted, “I wana go dance too! These pull-ups awe perfect for moving around!”
Luna smiled, “Alright, I’ll clear some space,” She then lit up her horn and placed a circle of magical power in the center of the room. The ponies all stared, as Discord and Nightmare Moon were placed inside the circlce. Luna told them, “Alright you two, when you’re done or need something, just ask for me, alright?”
Discord laughed as he shouted “Alwight Wuna!”
“Yeah, and than ya.” Nightmare Moon smiled. She looked around as all the ponies were watching them.
Discord blushed, “Alwight, weady?”
Nightmare Moon blushed, “Yeah Discowd, I weady. Wet’s show them what REAL dancing is!”
While Nightmare Moon and Discord danced to their heart’s content, Luna went through the palace and came to the buffet table. She saw Blueblood looking around with a pout.
Sombra, with a determined look on his face said, “Luna, tell Wawity I'll meet hew watew.” He jumped off Luna ,then started to crawl towards Blueblood. “Sombra, wait!” Luna shouted, but Sombra refused to listen!
Blueblood was looking around, when he felt something pull on his mane. He soon discovered the culprit, and he was anything but pleased, “Ahh! What the buck?!” he exclaimed!
Sombra hugged Blueblood’s neck and shouted, “I’m not weaving until ya my fwiend!”
Blueblood frantically galloped around shouting “Somepony help, Sombra’s hugging me!”
Everypony just laughed, as Luna smiled. Chrysalis laughed out loud, then said to Luna “I wana be bwuebood’s fwiend too!” She then teleported and appeared on Blueblood’s back, laughing and giggling, as Blueblood tried to shake off the foals.
Back on the dance floor, Discord held Nightmare Moon’s hooves. He bowed and asked, “May I have this dance?”
Nightmare Moon blushed and hugged her dress, “Of couse, Discowd.” They took their hooves and claws. Then they both stood up (with much difficulty on Discord’s part) then they waddled around with everypony just watching the two as ponies dawwed at the toddlers.
Discord looked up as he waddled around. Everything was quiet as the music was still playing. However, the chatter was very minimal. Suddenly, Discord saw one mare, then he looked back at Nightmare Moon in her dress and asked, “Hey, Moony, why do fillies weaw dwessies?”
Nightmare Moon shrugged, “I have no idea but I think it would be funny if everypony switched cwothes.”
Discord blushed, “Ya weally think so?”
Nightmare Moon smiled, “Ya it will be hiwaious.” And before she can say anything else Discord snapped his claw.
Blueblood was now outside, out of breath.
Sombra looked down at Blueblood’s face as he asked, “So ya weady to be my fwiend?”
Blueblood cried, “No, I don’t want to be your friend!”
Sombra pouted “Why not?”
“Because...because you were a villain and a evil king! That’s why!” Blueblood protested.
“So you awe a meanie poopy head!” Sombra retorted.
“I am not!” Blueblood shouted back. “Is that anyway to talk to the stallion that changed your dirty diapers, even when he’d rather be rotting in Tartarus?!”
Chrysalis giggled and poked her head, “Weww, I think ya need to lighten up.” she remarked.
“Whatever, Changeling Queen! You’re just as bad as Sombra!” Blueblood protested. “Thanks to you, my adopted sister’s wedding almost had to be cancelled! And after I spent all that money getting her a wedding present too!”
Chrysalis was furious, as she stuck out her tongue while her horn glowed, “Well if ya gonna act wike a wittle foal, then ya gonna be a wittle foal!” she remarked.
Blueblood’s eyes became hypnotized as he lisped. “Alwight what ya wana go pway?”
Sombra smiled, “How about we go to the buffet table and pway thewe?”
Blueblood galloped back to the palace shouting “Yeah, I wan cake!”
Sombra laughed and giggled, as did Chrysalis. “Ya think we gonna get in twouble?” Sombra asked.
“Na, we jus pwaying. Thewe’s no hawm in that ,wight?” Chrysalis responded.
In the ballroom, Fluttershy saw a bright light and then saw her dress turning into a suit, she blushed seeing that it was designed for a stallion, due to being a bit bulky.
Twilight (who was talking with Fluttershy), was now wearing what looked like Shining’s suit.
Rarity screamed the loudest, seeing that her dress was now a fancy purple suit!
Fluttershy had a feeling what had happened, and she turned just in timeto see Luna flying back into the ballrooom! Fluttershy followed the princess, the two seeing Discord and Nightmare Moon laughing, and the ponies in the ballroom either laughing or shouting at Discord. “Discord!” Fluttershy bellowed.
Discord turned around and gulped, as he saw Fluttershy’s disappointed face and him in a dress. “Oh no, we in twouble!” he told Nightmare Moon.
Luna released the shield, allowing Fluttershy to pick up Discord and Nightmare Moon.
That was when they heard Sombra shout ”Hold on!” and a large crash that followed right after. The ponies turned to see Blueblood, dressed in a beautiful white dress, crash into the cake, with two ponies playing in it, babbling and shouting happily.
Then Blueblood got up, laughing with the two, as he started smearing cake on his hooves and placing them in his mouth, while babbling gibberish. All the ponies surrounding him started laughing, and soon the rest of the mares, now seeing how hilarious their husbands or coltfriend looked in dresses began to laugh too.
Luna smiled slightly, as everypony was relaxing. Then Celestia came in and saw the mess and the swapping of clothes. Then she had to stifle a laugh before sighing, “Discord.”
Discord rolled his eyes then snapped his claws. The party was over.
The six mares were with the foals in Celestia’s room, as Celestia came up to the four, all of them sitting on her bed. The sun princesses sighed, “After all this time and work you four are still quite naughty.” They all began to cry as Celestia tried to stifle a laugh, “It’s alright, I should have expected something like this was going to happen.” she told them.
Discord blushed, “I sowie, I jus wana see what the stawions would wike in dwessies.”
“Yeah, I did too. I was the one who gave him the idea.” Nightmare Moon confessed.
“What are you talking about?! That was great, and nopony got hurt!” Pinkie replied.
Discord bowed his head as Fluttershy looked over him, “You’re still going to be punished though. What do you did was wrong, it’s not nice to play tricks on ponies like that.”
Pinkie, reluctantly agreeing with Fluttershy, sighed, “She’s right,” she said, as she picked up Nightmare Moon. “Messing with ponies just for the fun of it isn’t funny. Pranks like whoopie cushions or squirting flowers are harmless fun, but swapping everypony’s dresses isn’t. Some ponies payed good money to look their finest.”
Rarity smiled at Sombra as Sombra blushed, ”Don't think you’re going to get out of trouble, just because you’re in my care,” Rarity warned him. “While I’m happy to say that Blueblood got what he deserved, the fact of the matter is you still brainwashed him. And even royal pains like him don’t deserve such cruelty.” She then picked him up, as he looked back at Celestia. Celestia smiled at him as he waved goodbye to her.
Then Applejack picked up Chrysalis, and briefly mentioned that she would be in trouble for hypnotizing Blueblood, and then everypony but the two sisters left Celestia’s room.
When the room was void of foals, Celestia laughed, “Well that was one way for Sombra to say goodbye. I don’t think I’ll ever be forgetting it.”
Luna looked at her sister, “You think Blueblood lightened up a bit?”
Celestia sighed, “I hope so.”
When Rarity came back to her boutique with Sombra, she brought him up to her room. As she laid him on the bed she then said, “Sorry Darling, your room isn't ready yet. I hope you don’t mind.”
Sombra was sniffling as he nodded. “I jus wanted to make Bwuebwood waugh.” he confessed.
Rarity smiled, “And you did. But making Blueblood act like a foal wasn’t nice. I do hope you’ve learned you lesson about that.”
Sombra muttered, “Well he could of just been nice.”
“Indeed he could have, but that doesn’t mean your behavior was acceptable.” Rarity briefly scolded, as she took off his foal clothes, leaving him in his poofy blue diaper.
As Rarity placed a small star symbol on his diaper, Sombra asked. “Wha is that?”
“This is something Twilight wanted to give you to control your powers until she can teach you how to use them.,” Rarity explained. “We can’t keep having incidents like this.”
Sombra nodded. “You wight, we got a wot of wok to do befowe we can contwol owa powas. I pwomice I wont eva use my powas withou pewmission again.”
Rarity smiled, “It's fine. Besides, I think it was quite cute what you did to Blueblood, he needed to get out of his shell.”
Sombra smiled and laughed, “ha weally?”
Rarity smiled, then brushed his mane. She then laid on the bed next to him and nuzzled close to her.
“Wawity..will it be okay if i have some of ya milkies?” Sombra asked, blushing a bit.
Rarity gave him a loving smile, then lifted him in her telekinesis to her crotch boobs, “Go right ahead and call me ‘Mama’ frrom now on.” she told Sombra.
“Okay mama.” Sombra replied, then went to the right one, grasped it, and started to suckle, while Rarity watched him with a content smile.
Discord was on Fluttershy’s bed as she paced back and forth in front of him and finally said, “Alright, Discord I thought it over, and your only punishment is that you’ll be grounded for a few days...But I need you to stop playing tricks on other ponies.”
Discord whined, “But I wasn’t weally twying to pway a twick I jus wanted to make Nighmawe Moon waugh.”
Fluttershy sighed, “Discord, pranks can go too far, and I think this one did.”
Discord mumbled, “Alwight, I guess it was a wittle too faw.”
Fluttershy then came over and sat on the bed. She stripped Discord of his onesie, and slapped a gold star on his diaper. “Until you can use your powers properly, I have to put this on you.” she told him.
Discord reluctantly nodded, “Alwight, so Twilie is going to teach us again?” he asked.
”That's right. And this time, no putting her in in a diaper!” Fluttershy warned.
“Wight I twying to change, not her.” Discord joked.
Fluttershy giggled at the joke then picked Discord up and then placed him with her on the bed.
“Do ya fowigve me?” Discord asked as he bopped her on the nose.
Fluttershy smiled, “Of course I do. But I need you to listen to me, alright?”
Discord nodded again then went back into the covers, with Fluttershy covering him with one of her wings.
Applejack was with Chrysalis at Sweet Apple Acres, and was changing her diaper as Chrysalis mumbled, “So, I in twouble?”
Applejack replied, “No, but I’m very disappointed in you. I thought you knew better than that, especially since you’re since you’re gonna start potty trainin’ soon.”
Chrysalis looked down as applejack placed a new white diaper on her then placed a small yellow star on it and continued, “Until ya can learn to use your powers responsibly, Twiligh tells me I'm gonna have to use this to keep them in check.” she explained.
Chrysalis pouted and whimpered, “Alwight. I wasn twying to be mean this time, I jus wanted to play with Blueblood to make Sombra happy.”
Applejack giggled a bit, “Chrysalis ya gotta learn what’s acceptable as fun, and what’s mean. But I think I understand what you were tryin’ to do,” Chrysalis smiled at Applejack, who groaned as she felt her teats refilling with milk. “Now go on, have some applemilk,” Applejack encouraged. “And tomorrow we can discuss when to start gettin’ you on the potty. Granny Smith agrees that you’re old enough, and she’s been down this road plenty of times before.”
Chrysalis resettled herself, then turned herself into a ball and started to suckle.
At Sugarcube Corner, Pinkie was in the upstairs bathroom, helping Nightmare Moon go potty. She helped pull down Nightmare Moon’s pull-up, then lifted her dress so Nightmare Moon could sit down on her potty. It was a small plastic bowl that was a midnight blue in color (modeled after Princess Luna’s coat).
After Nightmare Moon grunted and did her business, she happily shouted “Mama, Ii went potty!”
Pinkie nuzzled her and cooed, “Good job,”She then helped Nightmare Moon wipe, then put her pull-up back on as she added, “You're growing up so fast.”
Nightmare Moon blushed. “Thanks Mama.”
Pinkie then placed a gold star on Nightmare Moon’s pull-up and while she was emptying out the potty she told Nightmare Moon, “Now I'm just putting this on because Twilight said we still need to teach you how to use your powers for good.” After emptying the potty, flushing the toilet, and washing her hooves, Pinkie scooped up Nightmare Moon and carried her out of the bathroom.
Nightmare Moon nodded reluctantly, “Alwight.”
When she was brought into Pinkie’s room (Pinkie and The Cakes didn’t want Pound and Pumpkin getting jealous of Nightmare Moon being in pull-ups. They wouldn’t be ready for potty training for a little while longer, perhaps a few more months). Nightmare Moon was placed onto Pinkie’s bed. And after climbing next to her, she sheepishly said “ Hey, I'm sowry fow wha happened.”
Pinkie laughed slightly “Oh Nightmare Moon, I’m sure you are. I know that Discord was just playing around. But he still needs to learn to control his magic, and so do you..”
Nightmare Moon nodded. “Yeah, I should've stopped him.” she realized.
“Well you are the oldest,” Pinkie commented “I think what you should do is be the example, show the others how they can use their powers for good, and for fun.”
Nightmare Moon gave Pinkie a puzzled look “How?” she asked.
Pinkie smiled, “Like when you give The Cake Twins nice dreams, that's using your powers the right way. When Twilight’s teaching you, show that to your siblings.”
Nightmare Moon pondered this statement, then said, “Alwight I’ww twy.”
Pinkie smiled, then nuzzled her young charge. “Alright, now get some sleep. But remember to wake me up if you have to go.”
Nightmare Moon nuzzled her mother, as Pinkie smiled gently and placed her head back on her pillow.
