Trixie blinked. Everything from the day before was a blur: She’d challenged Twilight to a magic duel to prove she was more powerful. She’d tried to perform an age spell. But after that she couldn’t remember a thing… what had happened? Did it go wrong somehow? She kicked about and felt something soft around her rump. What was it? She blinked, looking up to see a mobile over her head. There was something wrong, was that a mobile for foals? Why would she be sleeping under one? 

Trixie slowly rose up and could see bars surrounding her. Was she in prison? No, the bars were made of wood and painted pink. She looked down to see a mattress and found that she held a plush teddy bear in her hooves. Then she looked around at the soft pink blankets, it was all coming together! She looked down to see a thick, white diaper around her rump, rising to her stubby little legs as she placed her hooves on her cheeks. Now she realized what had happened, her age spell had backfired on her!

The regressed magician groaned, rubbing her hoof down her face. "How couwd tis happen?! Did Twiwight do tis?!" Just then, something “poofed” into her crib. 

Trixie turned to see that a small, grayish-purple coated little filly was there and she had a smug grin on her face as she replied. "Hewwo Twixie."

"Who awe ya?!" The blue coated filly cried out in surprise! 

The grayish-purple coated filly placed a hoof on her chest as she introduced herself. "I Stawwight Gwimmew. Fiwst off, I gots to apologize, ‘cause I ta one who tuwned ya into a foaw."

"What?!" Trixie was beyond furious as she shouted. "Ya ta one who did tis ta me?!"

"Weww, I just wediewcted ya age spew. But yes, I did, “ Starlight explained. “I couwd've tuwned Twiwight into a foaw, but ten she wouwd just get back to nowmaw somehow. So I gots a better idea instead, I just needs to stay one step ahead of hew and hew fwiends. Fow tat to happen I need ya spy fow me on Twiwy and hew fwiends."

Trixie was starting to like this plan but she was still rather angry at Starlight and snapped. "Ya fowgetting tat ya tuwned Twixie into a foaw!"

Starlight held out her pudgy hooves and cried out. "Weww, if ya do tis and hewp me defeat tem, not onwy wiww I turn ya back to nowmaw but ya can join me in creating a utopia."

Trixie tapped a hoof to her chin. "Otay, but I a foaw. Is not wike Twixie is gonna give ya wetter of wha's going on."

Starlight waddled over and plopped next to her fellow filly as she continued. "I’ww come by a week watew." She then placed a plush bear into Trixie’s hooves and continued. "Whenever ya neaw Twiwy, and she tawking about someting important, ya press tis button and it’ww wecowd everything."

Trixie smirked and replied. "Ah, I see. So Twixie just gotta act cute and record Twiwy's secwets. Ten when you come back, I give it to ya."

"Exactwwy. Ya do tat and we gonna defeat them once ahd fow aww!" Starlight exclaimed, her cheeks flushing pink as she replied. "I wiww come back in one week...as an aduwt of course. Tis is onwy tempowawy.”

"Wight." Trixie snickered, wondering what this mare looked like as an adult and if maybe they could be friends later. 

Starlight then waddled off as she waved a hoof and babbled. "Now, ya gots to pway nice and be a cute wittwe baby. Dun bwow ya covew."

The filly then suddenly disappeared, leaving Trixie with the spy teddy in her hooves. She held the plush bear close to her chest and nuzzled it. The regressed mare had to admit, the alicorn amulet was great but she had felt it taking over her mind, and who knows what would have happened if she let it continue.







Trixie laid back in her crib and pondered what would happen next. Then she turned to see Twilight getting up from her bed. 

The filly was starting to wake up, stretching her hooves as Twilight looked over with a smile. "Hello, Trixie. I'm guessing you need a diaper change?"

"No I dun!" Trixie shouted but squeaked as the violet coated unicorn gently lifted her from the crib and gave her padded rump a few pats. Trixie was quite embarrassed to feel her padding squelch.

Twilight, however, wasn't phased at all as she yawned. "Sorry, I'm just way too used to this by now. Even your dirty diapers don’t phase me anymore."  She lifted the little filly and placed her on a changing pad, going about cleaning her up. 

Trixie whined and kicked the whole time, getting rather fussy. "Stop tat! I ta Gweat and Powewfuw Trixie! Ya can't tweat me wike tis!"

"Oh, stop! I can't leave you waddling around in a soggy diaper." Twilight snickered out loud as she continued the diaper change. All the while, the blue coated filly tried to fight back, kicking and bawling. But this Twilight clearly had enough experience with foals to keep Trixie from falling off the changing table. In a few minutes, she’d dressed her charge in new padding and a cute purple onesie with little stars printed all over. Twilight looked down at the blue coated little filly with a smile. "Rarity made that just for you."

"Next time, I'ww make her weaw a diapee!" Trixie snapped back as she was quite tired of this patronizing. 

The violet coated unicorn just plopped the young filly on her back as Spike got up and looked over with a tired expression. "Guess Trixie decided to wake up early today?"

"She was out for most of the day yesterday, so I assumed she would wake up early. Besides, it's not the first time I've had to wake up early to care for foals." Twilight explained with a wink.

"Whatevew. So wha now, ya gonna feed me baby food?" Trixie grumbled in an irritated tone. 

The violet coated unicorn mare couldn't help but snicker under her breath as she chirped. "Yep! Get used to it Trixie, foals like yourself can't digest real food,"  Twilight slowly took the little filly downstairs, placing her in a pink high chair and strapping her in. "This was Cadence's for a while, I had a feeling I would need it again."

"Gweat, ya just bwagging how smart ya awe." Trixie grumbled. Despite the fact that it actually wasn't Twilight's fault she was like this, it was still irritating to be around the mare.

Twilight shook her head. "Nope, I'm just being prepared. You know that both Ponyville and Canterlot had a lot of ponies turning into babies over the past few years, right? I don't get why you even came back, Trixie."

"Trixie towd ya yestewday! I wanted payback fow what ya did to me!" Trixie shouted at the top of her lungs!

The violet coated unicorn mare rolled her eyes. "Seriously? Payback for what? You did it all to yourself, and you even got yourself turned into a foal by using spells beyond your understanding."

Trixie grumbled under her breath, she wanted to say something back but knew that she needed to get on Twilight's good side. "Otay, fine, get it. I should stop twying to get my vengeance on ya."

The unicorn mare then beamed a smile at the little filly as she went to a cabinet and took out two jars of foal food. "Seems you learned your lesson. And for being such a good filly you get to choose breakfast: Mashed Bananas or Mashed Strawberries?"

The blue-coated filly cursed under her breath, but she had to admit she was hungry. Like Starlighthad  said, she just had to deal with this patronizing for a week and then she could make Twilight suffer! She pointed at the jar of mashed bananas, and Twilight nodded. 

The violet unicorn then tied a bib around Trixie’s neck, then began to feed her the food by spoon. 

Trixie reluctantly chewed on the yellow mush. After a few scoops made it into her mouth. Trixie had to admit the food wasn't as bad as she thought it would be, it was actually rather sweet and tasty. 

Spoon feeding was soon done as Twilight wiped Trixie’s mouth and chirped. "Alright, now for part two."

"No, not gonna have ya breastmilk!" Trixie shouted! She placed her chubby hooves over her mouth as Twilight gave a snicker. "Nope, just formula for you." 

Twilight then plopped a bottle of formula into Trixie’s mouth. She watched Trixie suckle the formula with a motherly smile as the little unicorn filly glared at her, trying not to show that it was actually tasty. 

But Trixie didn't even notice when she finished the bottle as she popped it out and Twilight chirped. "There we go, all fed."

"Twixie tinks tat breakfast was otay, but my mama's food was way bettew." Trixie grumbled as the violet unicorn then spotted the pudgy foal's tummy. She took a hoof and tickled the little foal's belly while making funny faces. "Oh come now, let's turn that frown upside down."

Trixie tried not to, but found she couldn’t resist as she started to kick her little legs while babbling and cooing happily. 

The violet coated unicorn mare then picked Trixie up and nuzzled her. "Oh, you’re not so bad, cutie! Celestia and Luna were way fussier."

"Dun cawe, ta Gweat and Powewful Twixie is fussy!" Trixie cried out but then squeaked suddenly as she was placed over the violet unicorn mare's shoulder and given a few pats on her back, making her spit up.







After wiping Trixie's mouth, Twilight took her to the library where she sat down and placed the little foal in a playpen. 

Trixie looked over and babbled, "I not gonna pway with baby toys."

"You don't have to, but I can't have you wandering off without adult supervision," Twilight responded. She then cleared her throat as she asked, "So, I think it's time I explain what's going on with you. But um, do you want the good news first or the bad news?"

Trixie eyed Twilight; she knew that Starlight Glimmer was why her age spell failed, but she still wanted to know if this Twilight would turn her back to normal. "Otay, good news first."

The violet unicorn mare nodded and continued. "Ok, the good news is I've actually researched the age spell you used yesterday. I assume it simply backfired and calculated how much power I need. So I should have you back to normal eventually."

"And ta bad news?" Trixie grumbled.

Twilight gave the little filly a suspicious look but continued. "The bad news is you used the alicorn amulet to use that spell, and Celestia and Luna have already forbidden me from using it because it’s too dangerous. So I'll be practicing age spell magic and trying to learn how to turn you back to normal within a month at the latest. Hopefully, we'll get there sooner rather than later. But until then I'll be your caretaker, seeing as I don’t know who your parents are or how to reach them."

Trixie pouted, it was obvious that it could take longer than a month. That age spell would be almost impossible for any unicorn to perform under ordinary circumstances. At least now she was a spy for Starlight, and had been promised to be an adult within a week. She would just have to spy on Twilight, give Starlight the spy teddy and make that pompous unicorn pay for what she did to her. 

"Alright. I have a friendship lesson to write to Celestia, then we're off to Sugarcube Corner." Twilight proclaimed as she trotted over to her desk. 

Trixie was a bit confused and asked. "Why we going to tis Sugawcube Cownew?"

"Oh, for your regression day party. It was Pinkie's idea, but I think since you'll be a foal for a while you might as well meet the other regressed foals in Ponyville." Twilight replied as she started her report. 

Trixie pouted, plopping on her padded rump. The sooner Starlight could save her from this humiliation, the better!
