Big Macintosh and Applejack were both having a lunch break together at Sweet Apple Acres enjoying some dandelion sandwiches under the shade of a few apple trees. They then both saw something odd. There was a zap apple on the ground and it looked mushy and rotten. Applejack had a funny thought and snickered, "I dare ya twenty bits to eat that rotten zapp apple, Big Mac."

Big Mac shook his head and responded with a defiant. "Eenope."

Applejack eyed her brother and replied. "How about for forty bits?"

The stallion shook his head. "Eenope."

Applejack snorted and shouted. "How about sixty bits?"

The stallion tapped a hoof to his chin and responded. "How about a hundred bits? Make it worth my while?"

Applejack scoffed and shoved the zap apple in front of him. "Alright, it’s a deal. Now go on and eat it."

Big Mac eyed the apple seeing how gross and disgusting it looked. A bet was a bet though. So he slowly and reluctantly picked the mushy zap apple and threw it into his mouth as quickly as possible. He groaned while munching on the disgusting zap apple. What was he thinking?! It tasted awful! 

Applejack snickered and burst into laughter as Big Mac grumbled. "There, are ya happy now, sis?!"

Applejack couldn't help but laugh. "Well, now  comes the best part. I heard from Granny Smith that rotten zap apples can have funny side effects."

Big Macintosh gulped. "Er, like what? It's not like I'm gonna shrink like you did when you walked into poison joke," He slowly began to shrink just as he spoke. 

Applejack burst into even more laughter. "Speak for yourself, Big Mac! Or should I say, Little Mac?!"

Big Mac whimpered as he shrunk to a chubby little colt, his belly bulging out as he whined. "Wha-what's happenin’?!" 
 
Applejack gasped in surprise! She’d been expecting a funny side effect but definitely not something like this. She whispered. "Oh my Celestia, Big Mac! You're a toddler!"

Big Mac whined as he tried to waddle away, but the mare quickly scooped up her baby brother and ran off as fast as she could. There was only one pony who she could think of that would know what to do.





Applejack was quite nervous as she stomped up and down in Twilight's castle. The alicorn was looking Big Mac over with her horn and sighed, "So, Applejack, how did Big Mac end up like this exactly?"

Applejack groaned as she rubbed a hoof down her face. "Ugh, it was just a dare! A really stupid dare! I dared Big Mac to eat a rotten zap apple. I had no idea it would turn him into a baby. I just thought it’d do somethin’ funny like make him talk in a high pitched voice."

Twilight got up and explained. "Well it seems that the magic won’t leave his body. We have to wait until he lets it all out after the zap apple’s been digested. That could take a while and seeing how young he is, I think Big Mac is probably going to need diapers."

The little colt shook his head and replied. "Nuh uh, no way! I'm not gonna wear a diapee. Haven’t worn ‘em since I was three and a half."

Applejack shook her head and snapped back. "You’re not doin’ your business all over the house, mister. You're stayin’ in diapers until we can figure this out, " She then scooped up the fussy colt who was kicking all about as she proclaimed. "Looks like I'm gonna need to go buy some foal supplies."





When Applejack came back from the grocery store, she brought everything into the living room. There was dozens of packages filled with all kinds of foal items: Including diapers, wipes, powder, and even a training potty.

Apple Bloom and Granny Smith were all with Applejack, as the little baby colt was sitting down. They dawwed and cooed at him.

Applejack explained. "From what Twilight said, he's only gonna be a baby until he’s digested the mushy zap apple and let it all out. So just watch him and let him use his diapers like a foal."

Granny Smith was quite frustrated. “Alright, Applejack. But you’re gonna change him whenever he does somethin’. I did warn ya about eatin’ bad zap apples."

Apple Bloom however was ecstatic and was bouncing around in excitement as she chirped. “Oh I can't wait! I’m gonna be a big sister! It's goin’ to be so much fun!"

Big Mac kicked about in his new, thick white diaper diaper as he whined. "Nuh uh, and I wana go potty in ta big colt toiwet."

Applejack shook her head and replied. "Sorry, Big Mac, I don't want you fallin’ into the toilet. Now go on and play with Apple Bloom while I finish the apple buckin'. I won’t be long."

Big Macintosh crossed his pudgy hooves across his chest and grumbled. "Ya owe me big time aftew tis."

Applejack just gave his head a pat and cooed. "Oh, just have fun and try to enjoy yourself. It's not everyday you get to be a baby again."

Applejack left the living room as Big Mac sighed, reluctantly starting to stack blocks on top of each other. 

Apple Bloom sat down next to him and asked. "So, ya wanna use the big potty?"

Big Mac nodded and babbled. "Yeah, I do. Is not faiw that Applejackie’s keeping me in diapees. She ta one who dawed me to eat tat stupid appwe! I stiww a big pony!"

Apple Bloom blushed and responded. "Well...I could at least try puttin’ you on the big potty and see what happens. If everythin’ goes well maybe we can get ya into pull-ups?"

Big Mac squeaked in joy. "That sounds wike a wot of fun!" He then waddled as fast possible and ran down the hall, wanting to use the big potty. 

As the two earth ponies entered the bathroom, Apple Bloom set her little brother down and helped pull down his diaper. She then placed him carefully on the toilet and stepped back as she instructed. "Okay, now go on and do your buisness."

The little colt sat there and tried to go, but was unable to. As much as he tried nothing happened. With a frown he stood up. Then he squealed, falling into the porcelain bowl as his diaper swelled up! But he was quickly pulled out from the water and set back down soaking wet. 

Applejack suddenly came in with an angry glare printed on her face. "What in the hay is goin on here?!"

Apple Bloom blushed as she responded. "I was just tryin ta get Big Mac on the toilet is all."

Applejack shook her head. "Ya should've talked to me about it first. He's way too young to be usin the big potty," She took Big Mac and started taping him up back in a diaper as she grumbled. "Look at you all soakin’ wet. Seriously, ya could've drowned or gotten flushed."

Apple Bloom rolled your eyes. "You’re being way too overprotective. He was older than you not too long ago, sis."

Applejack snapped back. "What does that have to do with anythin’? He's a baby now and we have to take care of him. And it’d be easier if you weren’t doin’ things like this with him,"She finished strapping him up in a fresh diaper and made sure he was freshly powdered. After that she placed him on her back. "Now, I'm gonna take Big Mac to work with me. That way I can keep him out of trouble."

Apple Bloom rolled her eyes and scoffed. "You’re so overprotective. He’s probably gonna be strapped into so many diapers he can barley move."

Applejack smiled and chirped. "That sounds like a great idea, sugarcube! That way he can't go wanderin’ off!"

Apple Bloom squeaked in fright. "I was just jokin’! Don't do that for real!"

But Applejack was already bounding to the living room and taking out a few fresh diapers. She started to strap them over the little red coated colt's underbelly until there were three diapers strapped around his rump. The colt whined and kicked, but could do nothing as Applejack finished strapping him up in his padded prison. She smirked. "There, now you’re protected from everythin’. Big sis’ll make sure you don’t get hurt."

Big Mac whined more and kicked about while shouting. "Sewiouswy?! I dun need thwee diapees! I can bawewy move!"

Applejack popped a pacifier into his mouth and mothered. "Oh hush, you’re too young to think for yourself. Just enjoy the experience."  

The little colt whined and fused as bobbed the pacifier up and down in his mouth. Applejack then took him onto her back and bounced down towards the apple orchard.





Applejack was now going about, bucking apple trees. And Big Macintosh was sitting down in his diaper while on a playmat with some colorful blocks and plushies. He was angry at Applejack not only for having him turned into a foal, but also treating him like a helpless little foal.

The little colt sat there, pouting the whole time and trying to think of a way to escape to try to use the potty again. 

Applejack did seem rather busy and he finally felt the urge to pee, but he looked down at the tabs where they met on a light green landing zone. This made him grumble upon seeing that his hooves were quite clumsy, unable to take ahold of the flat and slick plastic tabs that surrounded the first diaper. He cried out in frustration, sllammed a hoof to the ground and whined. “Tis is stupid! How I gonna pwove tat I a big cowt to Abbwejackie!”

He then spotted Apple Bloom through the trees, which made him smile as she bounced over to him. “Huh, it seems that Applejack has you in quite the padded prsion.”

Big Macintosh nodded. “Yeah, ya gots ta hewp me take off these diapees, pwease! I wana  pwove tat I a big cowt.”

The filly smirked, taking out the training potty and placing it down. “Well, no worries I brought the trainin’ potty. Since ya can’t go to the potty, I figured I’d bring the potty to you.”

Big Mac squealed in delight, waddling over and shaking his enomrmous padded behind about. Then suddenly he tripped and squeaked as he plopped onto his padded bottom. 

Apple Bloom blushed and helped the little red coated colt out of his diapered prision. She finished untaping four of the diapers and giggled upon seeing that one was soaked and he squeaked in surprise. 

Big Mac tried to place his hooves over the soggy diaper, but Apple Bloom gave it a pat making the padding squish as she cooed. "Maybe you’re too small to use the potty."

Big Mac grumbled under his breath and whined. "Nu-uh! Can ya just take ta diapee off?! I wana use ta potty!"

Apple Bloom sighed. "Alright, I guess." She stripped the sodden diaper from his rump and wiped his crotch down with foal wipes. Afterwards she hoisted the little colt onto the plastic potty, making him blush as he crossed his forelges over his front. Apple Bloom cooed. "So, are you goin’ to go potty?" The little colt groaned as he tinkled into the potty and Apple Bloom clapped her hooves in joy. "Yay! Ya did it, Big Mac!" 

Applejack, having heard the commotion, walked over with an angry glare on her face. "Seriously, Apple Bloom, ya defying me again?"

Apple Bloom snapped back. "Yeah, ‘cause it's not fair that ya’re doin’ this to Big Mac. See, he can go potty?"

But suddenly, as Big Mac peed his body shrank and he grew even more chubbier as he fell down onto his bottom!

Applejack gasped in horror, taking out threew new diapers, quickly powdering him up and strapped him in the fresh padding. "See, I told ya he's not ready for the potty. He couldv'e hurt himself!"

Apple Bloom snapped back. "You’re crazy! How could him shrinkin’ a few inches do anythin’?! Ugh!"

Applejack hugged Big Macintosh. "Well don't you see he’s a baby now that needs to be watched and care for at all times?"

Big Mac grumbled and kicked about, but was helpless against Applejack placing him on her back. 

Apple Bloom responded. "How about we let Big Mac choose instead of us: Diapers or the potty. We can put him through some tests to see if he is big enough. If he fails it’s back to diapers, but if he wins he can wear pull-ups and use the trainin’ potty."

Applejack nodded. "Fine, I agree. So what should we do for the first test?"

Apple Bloom smirked. "Oh, I have a fun idea!"





That afternoon, Big Mac looked at three sippy cups filled with apple cider. He was now wearing a standard blue pull-up for colts with the training potty on one side of the room. Applejack responded. "Alright now, Big Mac. You’re gonna drink that apple cider so you’ll need to pee. Then you’re gonna run to the trainin’ potty and we’ll see if you can make it in time. "

Big Mac groaned but did as Applejack instructed. He started to chug down the apple cider. After a few minutes of nonstop chugging he saw that he finished all three cups, and then he threw them aside, feeling the strong urge to go pee. He waddled to the training potty as fast possible. But squeaked as he started to pee and drenched his pull-up. He whimpered in embarrassment as he scrunched his legs together. "No way! Is not my fauwt!"

Applejack crossed her hooves. "Looks like I won, Apple Bloom."

Apple Bloom waddled over. "Hey, he still has two challenges left."

Big Mac groaned and slammed a hoof to his face as Applejack took off his pul-lup and started cleaning him up, changing him into three diapers. Applejack scoffed. "Well it's time for me to take you up on the challenge."

She then took the potty and placed it down the hall, then placed obstacles along the way and explained. "Now, I know ya didn't pee all that cider out. So now you’re gonna have to get through all of this in diapers and reach the potty again. Think you can make it?"

Big Mac growled as he scratched the floor and ran down the hall as fast as possible. He had to climb over the playpen and wade through all the plastic balls, then pull himself up. He landed on his padded bottom. The little colt then ran at a wall made of packages of diaper and burst through, squeaking as the diapers burst out, covering him in the padding. But he managed to poke his head out and clambered out. He got on the potty, threw his tiny hooves up and cried out. "Awight, did it! Now get tis diapee off!"

Apple Bloom helped remove the diapers and placed the little colt on the training potty and he tinkled with a big smile. 

Applejack growled as Apple Bloom smirked. "There, now he has one more challenge he needs to do to prove to ya he doesn't need diapers."





Big Mac was now back in in a single diaper strapped around his rump. Applejack stood over the two as she explained the final trial. "Now, he has to wear three diapers for this challenge. He can play and do whatever he wants. If he can tell me before he feels the urge then I'll put him on the potty and he loses a diaper. However, if he makes a mess or pees his diaper I’ll strap another diaper around his rump. If he goes higher then three, he loses.”

Apple Bloom smirked and shouted. "Oh yeah! You’re on, sis!"

Big Mac just sighed. "So...wha awe we gonna do untiw I have ta go?"

Apple Bloom pulled out a board game "How about we play this?"

After an hour of playing, Big Mac won the game. But he forgot about potty training and squeaked as Applejack checked his diaper with a hoof. "Looks like I'm winnin’." She changed him and put him in two new diapers. Applejack then placed the little colt in a highchair and spoon-fed him applesauce. 

After a while, Big Mac groaned as he tried to run to the potty. Apple Bloom skipped over, helped remove his diapers and helped him on the potty. The little colt grunted as he pooped in his training potty.

Apple Bloom cheered. "Yeah! There you go, Big Mac! You’re doin’ it!"

Big Mac blushed, not really sure what to say as he was taken off the potty, wiped down and was strapped back into a single diaper. He then was placed on a sleeping mat for a nap as the little colt was quite tired. 

Apple Bloom watched him, hoping she can warn him if he needed to go. But the colt peed during his nap. She shouted at Applejack. "It’s not his fault! Bedwettin’ doesn't count!"

Applejack shook her head. "It does, now he gets another diaper," She then changed him again and placed him into three diapers. "One more and I win."

Apple Bloom groaned and Big Mac was trying to calm himself as he stacked blocks. But he squeaked, feeling the pang to pee. He tried to run to the potty once more and by the time two diapers were taken off, he plopped onto the potty and peed. “See, I did it!" He cheered. But just then the magic exploded, and he was now an infant baby babbling incoherent gibberish. 





In her castle, Twilight looked at the babbling and adorable Big Mac (who was in five bulging, thick, white diapers). The princess blushed and explained. "Well it seems the zap apple is more or less out of his system. But um...it seems that he wants to stay as a baby. And the magic from the zap apple is still in his system, so he might be like this for a while."

Applejack dawwed. "Well that's alright. We did try to potty train him."

Twilight blushed and explained, "I bet he loved it so much that he wanted to go back to his childhood."

Applejack dawwed, taking of the little babbling colt and hugging him. "Well that's alright, he can be the baby of the family for a while.”
