Starlight, Twilight's pupil, was on her way to Trixie's wagon. Why? Cause The Great and Powerful Trixie needs Starlight to help her with a magic trick she's been practicing.
Starlight trotted down the dirt path to Trixie's. She started muttering things under her breath "of course it HAS to be magic. Why can't it be for company or tea or something!?" Starlight then bumped into a blue and purple wagon. She was at Trixie's.
Starlight knocked three times on her door before the magician herself appeared behind it. "Starlight! You're here!" Trixie got out of the wagon and hugged Starlight tightly before pulling out a huge chest. Upon looking inside the chest, they could see a bunch of magician props, but that's not what Trixie was looking for. She had to dig in deeper until "AHA!" Trixie yelled, pulling out a dusty book. It had a blue cover with a bunch of old tattered pages inside.
"What's that?" Starlight asked Trixie, not expecting her to actually use a book for a magic trick.
"Oh, it's just a book I've been using to try out new spells. And well, one of them caught my eye." Trixie explained, opening up the book so that both Starlight and her could read it.
"Hmm, it's an age spell." Starlight said, reading the description.
"Ok. I already know that. It's supposed to transform you into a younger version of yourself!" Trixie explained, her horn lighting up with a light pink aura.
"Um, you do know that a younger version of us would be a foal, right?" Starlight asked.
"Don't be silly Starlight. A foal would be a MUCH younger version of us. But a teenager would be a younger version of ourselves." Starlight just facehoofed at her statement, but didn't think much of it as Trixie began to cast the old spell.
"Oh, so you wanted to cast the spell on me, huh?"
Trixie rolled her eyes at Starlight's question. "Obviously, duh."
Now Starlight rolled her eyes as Trixie's pink aura suddenly shot straight at her, engulfing her in Trixie's magic. Her eyes suddenly turned all white and Starlight could swear she felt herself shrink and shrink and shrink until she felt small. The spell was finally done and Starlight's now small body, thudded onto the cold ground.
Starlight's eyes finally started to open to somepony screaming her name.
"STARLIGHT!!!" Trixie screamed.
"Wha-" Starlight was about to say, but all that came out was foal babble that Trixie didn't understand.
"What are you- oh no! Oh nononononono!" Trixie exclaimed unhappily. Starlight was very confused as to why Trixie was acting this way.
"Trixie why are you acting like this?" But nopony understood her.
Trixie takes it that Starlight doesn't know yet so she grabbed her favorite mirror and showed her what she looked like. Starlight looked into it and saw herself as a...foal!?
Starlight started wailing at the top of her lungs "I dun wanna be a foal!"
"I'm so sorry Starlight, I never thought this would happen. I-I have no clue how to change you back, but maybe Twilight will."
Starlight just cried in response, refusing to let Twilight see her like this. Trixie didn't want to deal with this so she just teleported herself, Starlight, and the old book to Twilight's Castle.
"TWILIGHT!!!" Trixie yelled.
Twilight and Spike immediately rushed down.
"Trixie what's-" Twilight was about to yell when she saw a foal that looked like...
"STARLIGHT?!" Twilight yelled, running up to her, now, foalified pupil.
"NO! I don't want Twilight to see me in this state! Oh, how embarrassing!' Starlight thought as Twilight came closer, making her bawl. Why, why did Trixie HAVE to go to Twilight for this?!
"Oh, I didn't mean to upset you but...why are you a foal?" Starlight cried even harder.
"I uh, might have, accidentally used an old spell I stole from your library on Starlight, which ended up turning Starlight into a foal. I was hoping you could you know, find a counterspell for this." Trixie explained.
"Trixie?! You stole from my library!? AND tested one of it's spells on my pupil WITHOUT my knowledge?!" Twilight bursted out, clearly upset, which only made Starlight even more upset, eventually falling out of Trixie's hooves and onto the cold castle floor.
"Starlight! Are you alright?" Twilight asked levitating her student into her own arms. Starlight wanted to cry again, but her foalish instincts came in and she snuggled into Twilight's warm fur, making Twilight blush and Trixie snicker.
"Trixie, this isn't funny!" Twilight whined.
"Aww, but you and Starlight are sooo cute! I just couldn't resist!" Trixie exclaimed, laughing for a bit. Making Twilight blush even harder as Starlight snuggled in deeper. Which even made Twilight say "Aww." Even Spike had to d'aww before falling to the ground in laughter beside Trixie.
"Ok, you two. Haha, very funny. Now let's get serious. Obviously I need to see the book first." Twilight explained as Trixie and Spike got off the floor, their laughs no longer there.
"Of course." Trixie levitated the old spell book from behind her and showed it to Twilight, showing her the same spell she used on Starlight.
Twilight carefully read the aged spell and she couldn't believe what she just read.
"Nonononono! TRIXIE!" Twilight yelled, but still managing to hold Starlight close to her snuggly, warm body.
"Twilight, i'm standing right here." Trixie stated flatly.
"Sorry, but you used one of Starswirl the Bearded's old age spells on Starlight! No wonder she's a foal!"
"I knew that it was an age spell. But, I didn't think that it would turn Starlight into a foal!" Trixie said defensively.
"But, it literally says that it'll transform you into a younger version of yourself! What did you think it meant?!" Twilight asked, obviously annoyed.
"Um, I thought it would turn her into a teen..." Trixie said slowly, realizing her mistake.
"Really?!? You thought that Starswirl the Bearded would actually make an age spell to make a grown mare a teen?!?" Twilight asked, totally peeved.
"I can see that I was totally wrong! But, how do we change her back? I honestly just came here to get a counter spell or cure or something from you. Since you're a Princess and all. But, I guess all you want to do is yell at me!"
"Trixie! I don't know any counter spells for this. But, I can try to find one in the library, IF you help as well."
"Ugh, fine, fine. But only because Starlight is my best friend."
"Good. Now let's go."
Twilight and Trixie both walked to the library, and began searching through rows upon rows of books.
1 hour of book searching later...
Twilight popped her head out of a messy book pile. "Find anything!?"
Trixie popped her head out of her own book pile and shouted "No!"
Starlight was on the floor crying. She didn't want to restart her life. She just wanted to be a big pony again!
"I'm sorry Starlight but...I don't think I can help. But, maybe Princess Celestia can help?" But that made Starlight cry harder.
"Twilight!? We can't go to the Princess about it!" Trixie said, landing on the floor with an "OW!" She took little Starlight in her hooves.
"Why?"
"She'll throw me in a dungeon or something! It's obvious that age spell is illegal. Considering that even you don't know any counter spells. And we've been through this whole library!"
"Trixie, don't be ridiculous! Princess Celestia would never do that! Especially since you're innocent."
"But, isn't this illegal?"
"Why?"
"Because it's old and I shouldn't have mettled with it! Also, if it's written by Starswirl then, isn't it even more important and illegal!?" Trixie explained, although she does sound a bit crazy.
"Trixie. It's not illegal. If it was, then why was a copy of it in my castle library?" Twilight asked Trixie.
"Well. I guess it wouldn't hurt to go to Princess Celestia." Trixie said, but that didn't cheer up Starlight.
"I don't want to see Princess Celestia! How embarrassing it would be! Please Twilight! Please don't take me!" Starlight thought as she whined about the idea.
"Exactly! Now, let's go to Canterlot!" Twilight said, ready to go out the door. But she stopped and looked at Spike.
"Um Spike, could you look after the library while we're gone?"
"Sure."
"AND tell Princess Celestia that we're coming!?"
"Sure, i'll get to writing!" And Spike went to the library to find some scrolls and quills.
Twilight and Trixie (who was holding foal Starlight) ran out of the castle. And to the train station.
"All aboard!" The train conductor yelled. "Train to Canterlot leaves in 5 minutes!" He yelled again.
Trixie, Twilight and Starlight boarded the train after showing the conductor their tickets (including Starlight's).
Starlight, already knowing that meeting Celestia was inevitable, she stopped crying and remained with Trixie while Twilight was looking through that same book that Trixie had found.
"I can't find anything! And i've searched the WHOLE book and the spell itself! Even the WHOLE library! Yet I- Princess Twilight Sparkle- can't find anything remotely related to this spell or even a cure! I'm a failure! I-i'm so sorry Starlight." Twilight almost shedded a tear but before that could happen Trixie smacked her across the face, making Starlight giggle.
"Trixie! Wha-" Twilight was about to ask, but Trixie beat her to it.
"Princess Twilight Sparkle! Get a hold of yourself! Just because you can't find the cure, doesn't mean you're a failure! Now, i've heard Starlight talk a lot about you, and not once has she ever said you're a quitter!"
"But-"
"NO! I don't want to hear it! Now, stop apologizing and don't give up!" Trixie finished.
"Are you done?" Twilight asked cautiously.
"Yes." Trixie answered.
"Good. Cause I just wanna say, we're here." Twilight pointed outside.
"Oh. We're here." Trixie repeated.
Trixie, Starlight, and Twilight got off the train and into the fine city of Canterlot.
"Ok. Are you guys ready?" Twilight asked
Trixie took a deep breath before answering. "Yep."
"Good, now, this might feel weird. But, it's the fastest way there so..." Twilight droned on before she just suddenly lit up her horn, and before Trixie knew it, she, Starlight, and Twilight were in Princess Celestia's throne room.
Princess Celestia stood in front of the mares.
"Twilight, so nice to see you again. Spike informed me you were coming. What do I owe the pleasure?"
"Um, Princess Celestia. Trixie over here, used one of Starswirl The Bearded's oldest age spells. In the spell it said it was supposed to transform you into you're younger self. And Trixie thought that would mean transforming into a Teenager, but it instead, turned Starlight Glimmer into a foal. And, we came here for a counter spell." Twilight explained, making Trixie blush at the mention of her name.
"Alright, give me the spell book." Celestia said.
Twilight levitated the spell book to Celestia, making sure that it flipped to the same page as the spell.
Celestia read a mere sentence before gasping and letting it out of her magical grip.
"Princess, what is it?" Twilight asked, not expecting her to react that way.
"This, spell was created by Starswirl to provide an alternative method to stopping monsters such as Sombra. I-it has no cure because it was designed to be cast by him only, or a Princess. Which explains why it ended up in your castle library. How was Trixie able to cast this complex regression spell on Starlight Glimmer if she's not a Princess?"
"Starlight gave me lessons on how to cast complex spells and, I guess after some digging in my magical reserves I found the strength needed to cast the spell. But, I never knew that only a Princess can cast it. I guess I really am that powerful!" Trixie boasted after her explanation.
"Trixie! This is not the time nor place to be boasting or gloating! Understand?!" Twilight scolded.
"Yeah, yeah." Trixie said dismissively.
"Ugh. Anyways, are you certain we can't turn Starlight back into an adult? Or at least try?" Twilight asked, but she knew the answer.
"Yes. I'm certain. She'll just have to relive her foalhood all over again. But, Twilight." Celestia started.
"Yes Princess?"
"Before you go, I must tell you that her mind will also be regressed."
"As in?"
"As in her memories of you, or anyone else that became her friend, will be erased. She will literally start her life all over again. So, you must find somepony suitable to take care of her and become her mom/dad."
"Oh. I-I wish I could but, i've got too many responsibilities as a Princess. And Trixie is a terrible choice because she lives in a wagon and is way too busy with her magic shows to take care of a foal!"
"Well, that may be true and all, but who else besides me or you could take care of her as if she was their daughter?"
"I might know. But, I hope he's up to the task. Since he's Flurry's foalsitter and crystaller. But, I think he could handle it. Plus he knows Starlight better than we do. He's the perfect choice!" Twilight explained.
"Are you suggesting Sunburst?!" Trixie asked.
"Y-yes. Why?"
"Because he lives in the Crystal Empire! That's why!" Trixie yelled. Which made Starlight cry.
"I cawn't wet Sunburst see me wike dis! He'ww waph or worse, he'ww wease me ta no ewnd!" Of course, all they could hear were screams and wails and foal babbles. What was the use of her speaking if they couldn't even understand her.
"H-hey, it's ok. I'm sure Sunburst will say yes. He'll make a great dad. You'll see." Twilight said, cradling her after taking her from Trixie's grasp.
"I not so sure Twiwight." Starlight babbled again.
"Sunburst seems to be your best option so far so, go and see him." Celestia said, ushering them out of her throne room.
Twilight and Trixie walked up to the front door of Sunburst's house and knocked. Starlight was trying so hard not to cry but considering the situation, it was almost impossible for her not to shed at least a tear or two.
"Relax Starlight, I know that Sunburst will understand, and he won't make fun of you." Trixie said, trying to calm her nerves down.
Starlight breathed once more before putting on her brave face, ready to face Sunburst.
"I'm comin'!" Sunburst yelled as he got up to the door.
He opened the door and what a surprise it was. "Twilight! Trixie! What are you doing here?"
"Sunburst, may we come in?" Twilight asked.
"Sure." Sunburst replied as he let Twilight and Trixie follow him inside. Making sure to close the door behind them.
"So, what do I owe this surprise visit?" Sunburst asked.
"Sunburst, if you haven't already noticed, Starlight is now a foal. And she needs a daddy. And I thought you could be her daddy." Twilight tried explaining.
"What do you...?" Sunburst was about to say, but then he saw a little purple maned foal in Twilight's hooves. Trying to bury herself in her fur.
"Starlight?" Sunburst asked, trying to get her attention.
She looked at Sunburst and looked a bit confused.
"Dadda?" Starlight asked. That time, everypony knew what she just said.
"Uh.." Sunburst said, speechless.
"Did she just?" Trixie tried asking.
"I-I think Starlight's memories are starting to fade. A side effect of the regression. As in, she must not recognize Sunburst. Which probably means she won't recognize us either." Twilight explained.
"She was regressed!? By who?"
"By Trixie." Trixie smiled sheepishly at her name being mentioned.
"What!? Why would you do that?" Sunburst asked, clearly not happy.
"I-I thought it would be cool to use for my next act so I used it on Starlight to see if it works." Trixie tried explaining.
"What?! Why would you even try to use a regression spell?!" Sunburst said, his face turning a bit red.
"I-"
"She thought it would be cool." Twilight interrupted, flatly.
She looked down at Starlight and she started yelling and crying for her dad, thinking that Twilight was foalnapping her.
"Can you stop yelling at Trixie and take Starlight!" Twilight yelled, breaking up Sunburst' argument.
"Sorry." Sunburst apologized as he magically levitated Starlight into his hooves.
"Hey, hey, hey. Don't worry Starlight, Daddy's here." He said, but suddenly blushed as he said the word 'Daddy'.
"Did I-" Sunburst said, though everyone already knew he did.
"Don't worry. You'll make a great dad. Besides, she already called you Daddy." Twilight said.
"Yeah but, I have no foal supplies! How can I take care of her?"
"Uh, go buy some or ask Cadence for some?" Twilight said, as she Trixie left the two, closing the door behind them.
"*sigh* guess it's just you and me, Starlight." Sunburst said, smiling.
"Baba!!!" Starlight yelled.
"But I don't have one! I need to go to the store and buy one first. So let's go." Sunburst said as he left his house and entered the town square, searching for a certain foal store.
Sunburst entered a foal store called 'Sunshine's Amazing Foal Store and More!'.
He placed Starlight in one of the pink carts, and began the shopping, while Starlight kept whining for a bottle.
"Hang on Starlight, we need other supplies besides a bottle."
Sunburst went down the diaper aisle. He already knew which brand was the best. The one's that Flurry wore, Ms. Sunshine's Princess Print Disposable diapers. The other print was Wonderbolt Print, and that wouldn't suit Starlight at all. He took the big 50 pack and placed it in his cart, making sure to grab foal powder, foal wipes, and rash cream. Once he was done he went into the next aisle, which had various foal bottles lined up on each shelf, making Starlight whine even more.
Once Starlight was in reach of a bottle, she tried grabbing it. Sunburst levitated the bottle away from her as he put it in the cart. But Starlight wanted another one, and tried grabbing another one, making one or two fall off the shelf and onto the floor.
After picking the bottles off the floor, Sunburst scolded Starlight as he moved the cart away.
"Starlight! You can't just grab things off the shelf because you want it! You made them fall! And what if that was glass? You could have seriously hurt yourself. Besides, I already put the first one you grabbed in the cart."
"Bu I wanna baba!!!" Starlight screamed, kicking her hind legs in frustration.
"Starlight! You're making a scene. Come on now, let's go get you a paci and some toys."
"Baba!" Starlight screamed again, preparing to light up her little horn.
Sunburst just ignored her as he pushed his cart to the Pacifier and Blankets aisle.
Sunburst started humming as he began to look at the different pacifiers.
"Hmm, Starlight? Do you like Pink with stars or Purple with flowers?" Sunburst asked as he presented the two pacifiers to Starlight.
Starlight stopped her whining and looked at the two choices. Since she wasn't going to get her bottle anytime soon, she might as well pick before Daddy picks for her.
She pointed to the pink one. Much better design than flowers. Ew. Maybe she'd get to suckle on it afterwards.
"Alright Starlight. Star design it is! Here, to keep you occupied." Sunburst said as he placed the star designed pacifier into her mouth while the other went back onto the shelf.
Starlight soon forgot about her bottle and concentrated on the rhythm of her suckles, while Sunburst began to look at the blankets. Since this store has the most comfortable blankets for foals ever, it wasn't too hard of a decision. But, he still wanted Starlight's opinion. So, he showed her some options.
"Starlight, would you like the one matching your paci or this beautiful mint green one?"
Starlight really liked stars so, she picked the star design one.
"Alright." Sunburst muttered as he placed the star one in the cart and the mint one on the shelf.
He was close to being done, but he still needed to get some toys. He'll worry about the crib installation later.
Sunburst pushed the cart to the toy section. Making sure he get's a mix of everything.
"Hmm. Is it better for her to have wooden or plastic blocks?" Sunburst asked himself.
He tried weighing them out but, in the end, he had to ask one of the staff members. He knew Flurry had Plastic blocks but...he wasn't sure if wooden was better and if plastic blocks were better or worse for Starlight.
"Um, excuse me?" Sunburst asked a light pink mare with a fuchsia mane and tail. Both were tied up into a neat bun. She was a unicorn.
"Yes?" She asked.
"I'm Sunburst and I was wondering...are plastic blocks better than wooden blocks or...?"
"I'm Fuchsia Blush and I think it depends on the foal. Like, if they like to chew on things or have growing teeth than, plastic would be better. But wooden blocks could be better for foals that like to make towers and push them over because if it were to fall it wouldn't potentially break, raising low risk for the foal. And wooden blocks would be a bit better for the environment overall. So, wooden blocks would be a way to go." Fuchsia Blush answered.
"Alright, wooden it is! Thank you Ms. Blush." Sunburst thanked, levitating a bag of wooden blocks into his cart.
"No problem. Have a good day, Mr. Sunburst."
Sunburst blushed as Fuchsia walked away to help another customer.
He looked for some stuffed toys and found a cute pink teddy bear.
"Oh Starlight! Look what I found." Sunburst sing-songed, levitating the bear to Starlight.
Starlight got out of her trance as she looked at the pink bear. She reached out her hooves. Oh, how she wanted to cuddle her!
Sunburst just chuckled as he let Starlight hug the teddy bear. He took out her pacifier so she could speak.
"So, what's her name?" Sunburst asked his filly.
"Hew name is Mowwy." Starlight said.
The only thing Sunburst got out of that was Molly.
"That's a nice name. Here's your paci." Sunburst placed the pacifier back into her mouth.
Sunburst kept looking for more toys. But, the only other toys he needed would be bath toys because, Starlight isn't of age to play with dolls and...it might be better if Starlight only had one stuffed animal right now, so he went straight to the bath section.
Sunburst decided to start with the rubber ducks. He took the original yellow duck, and then a few pink and green ones. He then went through some other toys but they weren't all that great. At least there were still some plastic boats. But, that's all he got. He also got some foal shampoo and body wash.
He was almost done! He just needed some onesies and that's it! He made the cart into a racecar and raced to the sleepwear section, making Starlight giggle behind her pacifier. They were in the aisle in a matter of seconds. He began looking over at all of the pretty colors until...he found one that matched her pacifier and so, placed that one in the cart as well as a nice purple and mint green onesie.
"There, that should be it. We'll look into strollers and crib installation later." Sunburst said as he raced to the cash register to pay. Then Sunburst placed Starlight on his back as he levitated all of the bags of foal supplies as he walked home.
Sunburst entered his house. He walked into the living room and placed all of the bags of foal supplies on the floor and took out the bottle he just bought. He then prepared the bottle for Starlight.
"Alright Starlight. Since you really wanted your baba so, here ya go." Sunburst replaced her paci with her baba and let her drink.
Starlight greedily drank the milk. She was really hungry. Like, REALLY hungry. She had to take breaths in between suckling, she even hiccuped.
"Starlight, take it easy. The milk's not going anywhere." Sunburst said cautiously, causing Starlight to blush a bit before suckling the last bit of milk left.
Sunburst burped Starlight and placed the pacifier back in her mouth, she began suckling it again. Sunburst also gave her teddy bear Molly to cuddle while he got his living room ready. Starlight ended up taking a nap.
