Chapter Six: Trixie's Many Firsts

Trixie had an adorable pout on her face, looking rather annoyed as she was being pushed down the street by Twilight, who was simply humming a tune to herself. The little blue filly was pouty due to the fact she had just endured a few hours of having to do an embarrassing magic show routine and was just glad that it was over.

Trixie now looked around with an embarrassed expression on her face, seeing that she was wearing nothing but a diaper around her rump. At least, it was a simple white (and rather poofy) diaper. Still, Trixie couldn’t help but throw her hooves over her exposed padding and was trying her best to cover it up. The filly was starting to feel self-conscious from ponies continuing to stop by, waving their hooves at her, or commenting at how cute she looked.

Twilight took notice as she looked down at the foal with a reassuring smile and cooed. “Don’t be so shy all the time; who knows how long you’ll be like this? You might as well enjoy it.”

“Tats easy for ya to say!” Trixie snapped back at Twilight as she plopped her charge down into the stroller with a pout on her face. “Why we goin’ to Abbwejack’s anyway?”

The violet unicorn lifted her head up and continued. “Well, I can’t say for sure. But I figured you can play with Zecora while Applejack and I do some big pony things that we need to take care of.”

“Weawwy?” Trixie asked. “You so secwetive.”

“You have no idea.” Twilight snickered as she continued to push Trixie along without making a fuss.

The little filly then just settled back into the stroller and cuddled her spy teddy close to her. Despite having just come from a rather embarrassing morning with Twilight having Trixie couldn’t help but ponder about how relaxing it was being a foal: Being able to sleep in and just being fed bottles and some rather tasty oatmeal. She had to admit being a foal had its perks, minus the diapers and constant coddling, of course.

Trixie was lost in thought when she looked up rather suddenly and happened to notice that she was at the Apples’ house and there was Applejack opening the farmhouse door. “Hey, Twilight, glad to see you came!”

“Yes, it is; oh you should’ve seen how adorable Trixie was practicing all day for her show tomorrow. She’s definitely going to be the talk of the town.” Twilight chirped with a smile as she then walked inside and placed her little filly down into the playpen already setup.

Trixie’s cheeks flushed red at the compliment, knowing that her show would be both fun and rather embarrassing. As the little filly was plopped inside the playpen she took a moment to look around, seeing the toys were relatively simple: Some wooden blocks and a few plush animals all looking homemade. The little filly trotted over to the blocks as she decided just to try practicing using her magic while the adult mares continued their conversation.

“Oh, that does sound rather cute. Zecora’s mostly been just playin’ with her potions all mornin’. She’s trying to make smoke grenades for Trixie’s show tomorrow.” Applejack replied. Soon the mares were deep in a conversation about their charges, almost like they were actual moms.

The filly tried to pay attention, but she mostly concentrated her magic to lift blocks. “Come on; I can do it,” Trixie mumbled under her breath, taking all her strength to levitate the blocks and stacking them neatly on top of each other. The filly showed off a proud smile upon noticing that she was improving.

Just then, Big Mac trotted over with little Zecora on his back, and she waved a hoof upon seeing Trixie. “Hey, Twixie! Glad ta see ya came by!”

The little blue filly flashed a smile back, then waved a hoof at her friend and greeted her back. “Yeah...nice to see ya too! Wook! I can use my horn!”

“Oh, wow! You gettin’ better at tat!” Zecora commented with an astonished expression on her face.

As the big red stallion placed Zecora down in the playpen a moment later, Applejack turned to face her brother with a stern look and ordered, “hey Big Mac, you're gonna have to be watchin’ the foals while Twilight and I are gone. You keep an eye on them; I don’t want any funny business while we’re out.”

Big Mac gave a slight nod and a nervous sounding. “Ey’yup!”

The farm mare looked down at Zecora with a glare. “That means no makin’ potions and no potty trainin’ with Trixie while we’re gone, ya hear?!”

“Yes, Mama.” The zebra squeaked as she hid her face behind her hooves.

Applejack continued trotting over to Twilight and asked, “Now why don’t we do some pracitin’?”

“Right, we’d better get going,” The unicorn responded as she got up and trotted over to Applejack’s side. She then eyed Trixie as she said, “You better be on your best behavior as well.”

“Trixie will!” The filly snapped back as she used all of her energy and squinted, using her horn to place another wooden block on top of the others slowly. She gasped upon seeing that she’d done it without having a magic burst and clapped her hooves together. “Wook, Twiwy, I did it again! Ya, see?!”

Trixie’s adorable outbursts were greeted with a loud “Awwww!” by everypony around her.

The violet unicorn placed a hoof to her chest with tears in her eyes. “Oh, you're growing up so fast.”

Trixie gulped and lowered her gaze as she was now feeling somewhat embarrassed. It was so awkward getting praised for basically doing nothing, but it also felt really good for some reason.

Twilight slowly came over and nuzzled Trixie. “Oh, stop being so embarrassed. Your magic is progressing pretty well for a foal your age. Now just have fun and relax.”

Trixie eyed the two mares with a ton of questions going through her mind and asked. “Wha awe ya two even doing?”

Twilight booped Trixie’s nose then cooed. “Sorry, that’s a secret.” She then trotted off with Trixie watching Twilight with a glare, wondering what exactly was her rival up to?

“Hey, can I hewp ya build a tower?” Zecora asked with that lovely little smile of hers, interrupting Trixie’s thoughts.

The little blue filly gave a slight nod. “Yeah, tat’s fine.” Trixie was preoccupied with her own thoughts as she wondered about what she’d do next and what Twilight was doing with Applejack.


While Applejack and Twilight walked off, Trixie busied herself playing with plushies. The little filly thought and reflected on her predicament. She had more or less a guarantee of turning back to normal with the information she had on Twilight (who obviously had something that could derail Starlight’s plans). But if Twilight did have a way to change Trixie back to normal? Would it be better just to let Twilight cure her? Or what if it was the worst-case scenario: Twilight’s secret didn’t work, and then Starlight betrayed Trixie!? Would that mean she was stuck in diapers forever!”

Zecora, unaware of what was going on in Trixie’s mind, trotted over and asked. “Um...Twixie, awe ya doing otay?”

The little filly looked over at the zebra as an idea crossed her mind. She needed to figure out at least what Applejack and Twilight were doing in the apple orchard, and she also wanted to get out of these embarrassing diapers. So she replied. “Yeah, I fine...um Twixie gots a question?” And then she asked. “Can ya help me with potty training again? Twixie wants to twy it again.”

Zecora nodded, but she started to twiddle her hooves as she stammered. “Yeah, of course...but Mommy said we can’t do tat wight now.”

Trixie trotted over and gave Zecora the most adorable puppy dog eyes look. “Oh, come on! She outside doin’ somethin’! It’ww be quick, she’ll neva know.”

“I seriously want to, but…” Zecora pointed a hoof at Big Mac, who was sitting on a nearby couch, reading a book.

Trixie nodded, knowing they would have to ditch the big stallion to sneak to the potty. She started suckling on her hoof, thinking of a plan, “Hmmm. Mama said ya made some smoke bombs?”

“Yeah! I wanted to give them to ya for ta show!” Zecora squealed as she showed off some pink-colored plastic balls.

Trixie squealed as she took them into her hooves. “Wow! Tese wook amazing!”

The little zebra’s cheeks flushed pink as she admitted. “I haven’t tested tem yet, though.”

Trixie took one of the smoke bombs and brought a hoof to her mouth as she snickered. “Weww, why dun we test tem on ya uncwe?”

The little zebra started to get rather excited as she whispered. “Otay, sounds wike a plan...but we gotta make it wook wike an accident, so I dun get in twoubwe.”

Trixie then took one of the smoke bombs and snickered. “I have an idea! Just follow my wead!”


Without warning, the two foals began to throw stuff at each other, having a fun little game of using other plush toys as projectiles! Trixie then took the opportunity of picking up one of the smoke bombs and tossed it at Zecora: She ducked as the smoke bomb hit Big Mac, and the room was covered in a thick, white fog of smoke!

The zebra then took her friend by the hoof, and they ran off down the hall, giggling as they headed towards the bathroom together. They then went inside the bathroom as Zecora showed her friend a plastic pink training potty, and Trixie had a shy smile. “Ugh, do I have to?”

“Memba wast time? Ya barely even made it to ta twaining potty,” Zecora replied with a nod. She then pointed her hoof at the diaper and asked. “Now, do ya need help?”

“Yeah,” Trixie grumbled, standing on her back legs to let Zecora untape her diaper. When it came off. Trixie trotted about it feeling proud that the embarrassing diaper was finally gone! But she did sort of miss the warm, comfy padding around her rump.

“Come on! Get on the potty, quick!” Zecora exclaimed as she hastily placed Trixie down on the training potty.

There, the little blue filly’s cheeks flushed red as she asked. “Y...ya gonna watch me?!”

“Why not?” The zebra innocently asked.

Trixie was starting to feel even more embarrassed than being in diapers as she shouted! “ Just look away, pwease?!”

Zecora’s cheeks flushed pink again as she nevertheless looked away, soon hearing Trixie tinkle in the training potty. Trixie closed her eyes, being super embarrassed. But that feeling slowly melted away as she finished. Afterward, Trixie felt somewhat relieved and excited that she’d just gone potty as she squealed! “See, Zecowa?! I went potty all by myself! Did ya see tat?!”

“Yeah, I did! I told ya can do it!” Zecora squealed as the two little fillies hugged each other. The zebra then helped Trixie wipe, and with a great deal of effort, dumped the contents into the toilet.

As the little zebra flushed it all away, they could hear Big Mac shouting down the hall. “Hey, where did you foals run off to?!”

Trixie gnashed her teeth and cursed. She’d been hoping for more time since going potty wasn’t the only thing she was after. “Hey, Zecowa! Wanna see another twick?!” She called, straining herself to use her magic to push the little zebra into the toilet!

“Wha ya doin’?!” Zecora asked before she heard the sound of the toilet handle was pressed down with Trixie’s magic, and she screamed and spun helplessly around in the bowl as a result!

The little blue-coated filly ran off down the house as Zecora shouted! “Hey, whewe ya goin’?! Dun weave me!”

The blue-coated filly couldn’t respond as she continued running down the house; she needed to see what secret Twilight was hiding from her and figured this would probably be her only chance!


Trixie ran out the back door of the farmhouse, still bare-bottomed. With any luck, Big Mac would be distracted rescuing Zecora and wouldn’t be looking for her for a long time. She then slowly trotted over as she headed towards the orchard. When she saw Applejack with Twilight, she hid behind one of the apple trees keeping an eye on the two with a devilish smirk on her face. Trixie now had a devilish smirk on her face as she thought to herself that she’d done it! She was about to see what Twilight had been hiding from her!

With her spy teddy handy, Trixie turned it on and waited paitently.

“Alright, are you ready?” Twilight said to Applejack.

“Yeah, yeah. I'll only be a foal for a few seconds, right?” Applejack nervously asked.

“Yes...now please, just try to relax.” The unicorn whispered as she lit her horn and concentrated.

Trixie noticed the amulet around Twilight’s neck: It looked similar to the alicorn amulet, but this one had small horns, had a chubby face and stubby horn on its center, and it was bright pink. The amulet glowed as Applejack was slowly regressed in age.

When the magic tendrils dissipated, it revealed the farm mare with her hat now covering half her body. “What the hay di ya do to me,Twily?!” Applejack cried out as she threw the hat off, revealing that she was now a young filly, pudgy with thick little hooves and a stubby mane and tail.

Trixie had to stifle her laughs behind her hoof, seeing that the farm mare was now no older than maybe three.

Twilight clapped her hooves and squealed in delight. “Oh my Celestia! You look so adorable, Applejack!”

Applejack whined as she started doing a funny little dance. “Otay, now will ya turn me back to normal?!”

“Aww, does somepony needs to go potty? Or maybe you’d prefer a diaper?” The unicorn teased her regressed friend, knowing by now what that little dance usually meant.

The regressed farm mare started to throw a fit as she whined. “Just turn me back to normal, quickly!”

Twilight snickered, seeming to be rather enjoying seeing her friend in such an adorable state. But eventually she did as Applejack requested as she lit her horn. The little filly was turned back into an adult almost seamlessly.

“There, it worked! It can track the age a user is supposed to be at and even regresses on command to the year the user wants.” Twilight explained in a rather excited tone of voice.

Applejack was stunned, looking over her body while making sure everything was normal before she whispered. “Yeah...that was surreal…”

“Well, now if anypony gets regressed against their will, we can turn them back immediately, hopefully,” Twilight sighed, looking somewhat relieved at that prospect before she then continued. “But...I’ll need to test the amulet out a few more times to be sure. I’ll need to try it probably on pegasi and unicorns as well, but I should be able to turn Trixie back to normal.”

Applejack turned to face her friend and then asked. “Yeah, but what about her magic show? A lot of foals are actually looking forward to that, aren’t they?”

Trixie held close to the tree and even stopped breathing for a second. Would she be saved from being humiliated tomorrow?

Twilight shrugged as she stowed the amulet away in her diaper bag and declared. “I’ll let her decide if she wants to do it. Luna made her such adorable diapers, though.”

Trixie stepped back as she shut her teddy bear off. She had enough; now she knew the secret Twilight was keeping from her: An amulet that helps with age spells. That definitely would be a hindrance to Starlight’s plans. She had to steal that amulet! But...Twilight was supposedly able to turn her back to normal now; could it be done today? But if so, what then?

Trixie thought hard. She hadn’t forgotten how Twilight had humiliated her a year ago and how Twilight had been treating her like a helpless foal! And not only that, she’d been making Trixie wear humiliating diapers and clothes! “No,” She thought to herself. “I don’t just want to turn back to normal anymore! I want to see Starlight’s plan come to fruition!” So, for now, she’d stay a foal and just steal the amulet instead!

“Hey, there ya are!” Big Mac exclaimed as he trotted over towards the filly looking somewhat relieved as he picked Trixie up and asked. “What were ya doing out here all alone?”

“Um...I...um… wanna see apple twees? Can you buck some abbwes, pwease?” Trixie stammered as she flashed her puppy dog eyes.

Big Mac gave a small daww now being completely hypnotized by Trixie’s adorableness as he then nuzzled her. “Alright. You shouldn’t be runnin’ off by yourself, but I can show ya how to buck apples for a bit if ya want.”

“Yeah! Tat sounds like fun!” Zecora exclaimed, looking only slightly worse for wear after what Trixie had done to her.

“But somepony needs a diaper first, even if Zecora says you went potty.” Big Mac chuckled as he laid the little filly down on a changing pad he’d brought with him and started to tape her up in a fresh diaper.

Trixie grumbled under her breath but allowed the strong stallion to tape her up in a fresh diaper. It was a small price to pay for the sweet victory of not only knowing Twilight’s secret but also progress on using her magic and using the potty! After Trixie was padded up in a fresh diaper, she trotted over, feeling rather comfortable with the padding around her rump.

Zecora turned and waved a hoof at her. “Hey, gwad to see ya otay! I was worry when ya just wan off wike tat. Ya gotta warn me ta next time ya gonna do tat, ya almost made be wike Hoity Toity and Bwuebwood who went down the howe! My diapee saved me!”

“I knew ya’d be otay; I needed to make a distraction,” The filly apologized. “I just weally wanted to see aww tese abbwe tees!” She exclaimed with a cute grin.

“Oh yeah, tey awe pretty coow. I love watchin’ Applejack and Big Mac buck the tees all ta time!” The little zebra commented back.

Trixie trotted over and plopped down next to Zecora. “Otay ten, wets watch together!”

Big Mac scooted the foals back a bit. “Ok, just y’all stay back here, alright?”

The two foals nodded and watched in anticipation to see Big Mac’s thick hooves smack into the apple tree that was in front of them. The tree shook as apples plopped down in the baskets below, making the foals coo in delight. Big Mac continued to smack the trees repeatedly as he continued to make apples rain down into the baskets below.

Trixie and Zecora clapped their hooves, both being rather impressed by the earth pony’s strength.

Trixie then trotted over and tapped at Big Mac’s leg. “Uh...Big Mac ca...can I twy?”

“Sure, go ahead. But be careful.” Big Mac cooed. He gently let the filly face her padded rump at the tree, watching as she started to smack the base of the tree with her tiny back hooves.

Zecora stood up, cheering her friend on. “Come on, Twixie! Ya can do it!”

Trixie kept on smacking her hooves into the tree until a single apple fell from the tree and plopped into the basket below. The little filly stood there, heaving with sweat all over but with a proud smile on her face.

“You did such a great job!” Trixie heard Twilight cheer as the unicorn trotted over, picked the filly up in her magic, and nuzzled her.

The little filly couldn’t help but flash Twilight a smile. So many firsts today: Her first time really using magic, going potty, finding out secrets, and even bucking apples! It was a great little day full of small little victories.

Twilight promptly placed her charge down into a stroller, strapping her in. “Alright, we’d better get going. I have to tell Celestia what we learned, plus get Trixie to take her nap.”

“I not tired!” The filly whined but then gave out a rather cute yawn making everypony dawww.

Applejack scratched her head, eyeing the little filly as she asked out loud. “Say, what was Trixie doin’ out here in the first place?”

“Oh...um…” Big Mac stammered.

Trixie knew she had to say something to remove any suspicion. So she looked over at Applejack and soon said. “Is just tat I wanted to see Big Mac buck abbwes and wan outside to have him chase me!”

Zecora bounced up and down. “Yeah, and guess what?! Twixie alwo went potty with a wittwe hewp fwom me!”

Trixie let out a groan as both Twilight and Applejack glared at Big Mac, who stepped back. “They threw a smoke bomb at me!” He nervously insisted.

Applejack then turned her anger at Zecora. “Is that true?”

The zebra’s cheeks turned a hot red as she whimpered. “Yeah, a wittwe…”

“Well, Twixie thwew ta smoke bomb! And Twixie awso wanted to go potty so dun bwame Zecowa, blame me!” Trixie exclaimed! Despite her hating being a foal, Zecora had been her one true friend throughout this ordeal, and she didn’t want her to get into trouble for her actions.

Twilight trotted over and ruffled Trixie’s mane. “Ok...well...did you use the training potty and not the big one?”

“Yeah...and Zecowa was ta one who flushed ta contents down the big potty,” Trixie replied, trying to be as blunt as possible and not wanting to go into details.

Twilight gave a nod as she replied, “Well, that clears things up. It seems nopony was hurt, and the foals seem rather happy, but I would advise we confiscate the smoke bombs.”

“Yeah, should’ve known they would only cause trouble.” Applejack growled and eyed her charge.

“Weww, wike Twilight said nothin’ happened,” Trixie quickly replied. “So why dun we get somethin’ to eat and then I’ve take a nap?”

“Sounds good to me!” Zecora squealed as she bounced up and down on the farm mare’s back as she, Applejack, and Big Mac headed back to the house.

Twilight then strapped Trixie into her stroller and gave her a playful nuzzle. “Alright, cutie, why don’t we get you home too?”

“Otay,” Trixie yawned. She didn’t want to admit it, but she was rather tuckered out. The little filly hugged her teddy, not even worrying if ponies see her in a diaper with her being too happy to care.


When Trixie got home to the overly pink padded library, Twilight was getting her charge ready for a nap, dressing her in a cute little purple sleeper.

Trixie was bouncing up and down in excitement, too giddy to stop as she chirped! “Hey, Twily! Did ya hear I went potty by myself?! I not gonna need diapees soon!”

Twilight placed a hoof over her chest and cooed. “Oh, I heard! You're growing up so fast,” The mare then pulled out the strange-looking alicorn amulet and continued. “Speaking about growing up, I think I can turn you back to normal now if you want.”

Trixie blushed, seeing Twilight had just revealed to her the amulet she spent all day trying to figure out. All that trouble, and it was all for nothing. But, the thing that nagged at Trixie’s brain now was this: Did she still want revenge on Twilight? Or maybe it was more than that; maybe she wanted to be a foal again. After all, she’d had so much fun doing things as a foal; it was an experience that couldn’t be replicated.

Trixie took a deep breath and said. “Wook....Twixie...dun mine being a baby fow a few more days, otay? Also, Twixie tinks ya should test it out more before ya use it on Twixie, just in case if ya make me younger.”

Twilight eyed Trixie, being a bit suspicious of her answer. “This morning, you were complaining about your diapers and now this? Are you up to somthing?”

“I’m not up to anything’, Twixie sure! And I wana do ta magic show tomorrow, otay?” Trixie responded rather suddenly. She knew that staying as a foal meant more embarrassment. But at the same time, Starlight’s utopia wouldn’t happen if Twilight had that amulet.

Twilight seemed not to notice the expression on Trixie’s face as she gave a nod. “Alright, well, I’m glad you decided on your own,” She then levitated Trixie into her crib and tucked the little foal under the blankets, plopping a pacifier into her mouth. Twilight kissed her charge on the cheek and whispered. “Ok, then have a nice nap.”

“Tank you mam-” Trixie clammed up as soon as the words left her mouth.

Twilight blinked looking rather surprise and asked. “What was that?”

“N...nothing, otay?!” Trixie cried out as she started to suckle her pacifier at a frantic pace. She couldn’t believe those words had come out of her mouth.

Twilight, however just gave a smirk and a nod before trotting to her desk to write to Celestia.

Trixie laid back, suckling her pacifier at a more rhythmic pace, unable to fall asleep. Why had she just called Twilight mama? She was not her mom! Now she regretted her decision and could only hope she didn’t grow too attached to Twilight.
