Dr. Whooves was quite embarrassed as he walked down the streets of Ponyville, now forced to wear something most humiliating around his rump. Due to the curse by Discord he was now in a pull-up, albeit a special one, and the stallion ducked his head down with a sheepish look on his face. He continued on his way, trying to avoid the gaze from onlookers. Despite the embarrassing waddle through the streets, he nonetheless continued trying to reach Sugarcube Corner without delay for he had been told his help was needed for a very important assignment in foal development.
It didn’t take long for the stallion to reach his destination. He opened the front doors of the cafe and saw Pinkie Pie bounce over with a big, cheery smile printed on her face. Dr Whooves cheeks flared red seeing the mare had bulging boobs under a cute, frilly white apron (another cure from Discord) as she exclaimed! “Hey Dr. Whoovesy! How ya doing?!”
The stallion was deeply embarrassed at all the commotion the pink earth pony was giving him as he simply waved a hoof and squeaked. “H-hey Pinkie Pie. I’m... doing okay. About as well as I can do given the circumstances.”
“Oh, that’s wonderful to hear! But you sound so depressed! Why is that?” Pinkie Pie asked with a curious look on her face as she bounced over with her ever so cheery smile.
The stallion stood there then scoffed as he tried not to roll his eyes. “Well, I’m not fond of training foals on ‘using the potty’ as you would put it.”
Pinkie chuckled as she went about serving patrons and cooed. “Oh come on, I would totally trade places and teach them myself. I mean, I tried it once before but you know how it turned out.”
“Oh I know. I understand you’re half the reason why this place hasn’t been buried under a mountain of diapers already. Doesn’t make my job any easier even if I’m not going to make the same mistakes.” The stallion grumbled as he waddled off with an irritable look on his face. The idea of having to serve as a potty training role model was humiliating.
Pinkie simply waved a hoof as she stood over the Cake Twins and spoon fed them as she chirped. “Oh, don’t be such a grouch. Try to have some fun like I did! Just don’t have too much fun, ‘cause we know what happens when that happens.”
Dr. Whooves said nothing, unable to argue with that logic. He continued up the steps of Sugarcube Corner and came into the bedroom Mrs. Cake shared with her husband.
The mare turned her attention to Dr. Whooves, who stood there with an embarrassed look on his face. “Oh, stop being so bashful. Come on over, let’s talk. I know why you’re here,” Mrs. Cake chirped, coming over to give the stallion’s pull-up a few pats as she dawwed in a motherly tone. “Oh, you’re dry, that’s good. And it seems you have about thirty minutes before you need to go again.”
Dr. Whooves stomped about and whined. “Stop doing that! Please! Do you have any idea how embarrassing that gets?”
“Oh, stop being so cute! Not everypony’s lucky enough to be wearing pull-ups right now you know.” She cooed pinching his cheeks and then waddling back to her bed.
The stallion, for his part, stood there and still blushing as he reluctantly commented. “So...um...you told me I could be useful in potty training your foals again, but I’m not sure how I’m supposed to do that.” Dr. Whooves stood in front of Mrs. Cake with a worried look still plastered on his face. He was quite nervous and was unsure of the mare’s new plan to toilet train the twins. He tried his best to pay attention as the plump baker opted to explain her new idea on how to toilet train her foals.
“My idea is quite simple,” Mrs. Cake explained as she held up a muffin. “I found this magic muffin on a plate the other day. When I tried one it turned me into a toddler and my husband had to care for me. I know it may be a bit embarrassing, but I saved one muffin so that it can turn you into a toddler. It got me to thinking.”
The idea was so insane and embarrassing it made the poor stallion buckle his knees together, scrunching his pull-up between his legs. “So...you want me to turn myself back into a toddler and be like their big brother?!”
Mrs. Cake’s face turned red as she continued to explain. “Yes, only for a little bit. I thought about doing it myself but I didn’t have enough self control. It seems this is a perfect opportunity while you still have to wear pull-ups since you won’t lose your control, and it won’t be as embarrassing with you being an example as an adult.”
Dr. Whooves face turned a bright red as he looked back at his padded rump and sighed. “Yeah, guess you’re right. Besides, your foals are used to looking up at you, not right at you.” The stallion was now walking back and forth. His face scrunched up from the embarrassing crinkling that was emanating from his pull-up. He was feeling quite anxious and unsure about this whole idea, though he couldn’t think of any better idea at the moment.
“That’s correct, now please eat the muffin. And don’t worry, I’ll make sure to take good care of you.” Mrs Cake cooed.
Dr. Whooves gulped as he eyed the muffin closely, seeing that it was the same as the muffins that Discord enchanted a few months ago. The muffins that had turned Pinkie Pie into a foal and the Cake Twins into adults. He took the muffin very reluctantly as he had already agreed to this, at least it was for a good cause. He slowly chewed on the muffin and his body slowly started to shrink. It was slow with his body decompressing into himself. His belly bloated out with foal fat and his hooves were now looking more like a chubby toddler’s, with a small wisp of black for a mane and tail.
The colt plopped down on his padded rump as a loud bunch of crinkles echoed throughout the room with a cute, confused look printed on his face.
Mrs. Cake came over and nuzzled his chubby cheeks as she cooed. “Oh, you’re just so cute!”
He blushed, rubbing his face and looking down at the thick padding between his legs. He squeaked when he noticed something was off about it! “Did my pull-up tuwn into a diapee?!”
The big blue coated mare came down to his level and gave his padding a few pokes, making it crinkle as she cooed. “Oh, it’s just a side effect. Now come on, I’ll get you in a pull-up.” She placed the colt down, untaped his diaper and slipped up a new pull-up around his rump.
The colt blushed seeing the magic hourglass appear, and the sands begin dripping down.
Once done, the mare gave a nod and took the colt by his hoof. She led him down the steps to see the Cake Twins.
The two young foals gasped upon seeing the toddler sized Dr. Whooves, who blushed as he waved a hoof in greeting. They quickly waddled over and gazed at him with surprised faces and wide eyes!
Pound Cake spoke up first as he babbled and exclaimed! “Wow! Ya so coow in tat puww-up!”
“Yeah, it wooks weawwy cute!” Pumpkin Cake shouted!
Dr. Whooves felt quite pestered by the two as they swarmed him. He stomped about and snapped. “Stop, ya two! Ya embewassin me! I here to teach ya how to go potty.”
Mrs. Cake gave them a cute smile and cooed. “Alright, come on you three, it’s time for num nums.” She placed the three into highchairs and began to spoon feed them some mashed yams.
Dr. Whooves crossed his chubby hooves and with a cute pout he whined. “I a toddwew, I shouwd at wea-” But he was cut off as the mashed yams were shoved into his mouth, and he begrudgingly munched on the foal food and swallowed it.
The mare cooed. “No talking while eating, sweetheart,” She continued to feed the colt mashed yams, the orange mush getting all over his face. The same thing happened with her children, not that she seemed to mind. After they were fed the foal food and their mouths were wiped clean, she placed them down, and nearly gasped as she saw the sands in the hourglass were almost to the bottom! Pinkie had told her what that meant! “Dr. Whooves, it’s time to go potty! Come on, children!”
He groaned but was led off by the mare upstairs and to the bathroom as Mrs. Cake explained. “Now Pound, Pumpkin, pay attention.I know you already learned a little from Pinkie but it never hurts to refresh your memory. First we pull down the pull-up, like so.” She did so rather gently, then placed Dr. Whooves on the training potty and watched as he tinkled in front of the twins (and her).
Dr. Whooves blushed as pee filled the training potty almost to the brim. Once done he was lifted off the training potty and his rump was wiped with foal wipes, then his pull-up was placed over him. “There. Such a good colt.” She cooed.
Dr. Whooves smiled and exclaimed. “Yeah! See? Tat's how ya use ta training potty!”
“Wow, ya so coow!” Pound Cake shouted in awe!
Pumpkin Cake also exclaimed! “Yeah, ya amazing! Ya made it wook so easy!”
“Well..um..ya two wanna twy?” Dr. Whooves sheepishly asked them.
“Yeah! We wanna twy, we wanna twy!” The two foals exclaimed as they bounced up and down!
So Dr. Whooves stood back and watched the two as Mrs. Cake assisted them with their training. He did feel proud at helping these little foals achieve a huge milestone in their lives, even if it was probably for the second time. But then a thought struck him. As Mrs. Cake walked over, he looked up and reluctantly asked. “Uh, how wong do ya want me to do tis fow, Mrs. Cake?”
“Oh, would it be ok if you stayed like this for a few days?” Mrs. Cake asked him. “I think my children learn best if they have somepony serve as an example to emulate. There should be enough of the magic muffins to last without making the transformation permanent.”
Dr. Whooves rubbed his mane in uncertainty. He was going to say no, but seeing the Cake Twins all happy and giddy over their success warmed his heart. With a smile he sighed. “Otay, tat’s fine, as wong as you pwomice it not pewmanent and I go back to being big pony when tis is ovew.”
“Of course. Now come on you three, it’s time for a nap.” Mrs. Cake cooed as she led the three out of the bathroom and down the hall to the nursery.
The colt sighed as he yawned. “Weww, a nap wouwdn’t be too bad. Wha’s the worst tat couwd happen?”
Dr. Whooves woke up in the Cake Twins’ crib sometime later, and squeaked feeling the harsh pang of needing to go pee. He looked down at his pull-up and saw the time on his hourglass, he only had a few minutes! He cried out as he climbed out of the crib and slammed onto his padded bottom, then ran off through the nursery and down the hall panting! “Gots to get to ta potty!”
The colt whimpered, feeling the urge to pee growing by the second! By some miracle he was able to make it to the bathroom, he slammed the door to it and groaned upon seeing the stupid plastic potty he used before hadn’t been emptied yet. So that meant there was only one thing to do, he’d have to be brave and try his luck with the “big potty”.
“Ugh, tis is gonna suck,” He groaned aloud as he slowly pulled his pull-up down, and climbed up and onto the toilet, Then he gasped upon seeing the Cake Twins peeking over. He whined. “Hey, stop watching me!”
The two just giggled as they waddled over and Pound Cake babbled. “We just wanted to see ya use the big potty. Ya gots to be cawefuw if ya dun wanna go down da howe.”
Pumpkin Cake nodded. “Yeah, is that otay?”
Dr. Whooves rolled his eyes and grumbled. “Fine! Now watch me, tis is how ya supposed to use the big potty!” But he squeaked as he lost his balance, falling off the seat and into a bowl with a splash!
The Cake Twins, fearful of a repeat of what happened with Pinkie Pie, ran over! Pumpkin Cake used her magic to lift Dr. Whooves out of the bowl, as Pound Cake fluttered down and helped carry him out of the toilet proper as they all plopped onto the ground!
A frightened Mrs. Cake burst in at that very moment and asked! “Are you three alright?!”
“Yes, Mama.” The Cake Twins chimed in unison.
Meanwhile, the mare came over to Dr. Whooves and asked him. “Are you okay?!”
“Yeah, I fine thanks to ya foaws. They saved me when I fawwed into the big potty,” Dr. Whooves explained. “Sowie, didn’ mean to cause aww tis twobwe.”
The colt whimpered and rubbed his eyes as Mrs. Cake nuzzled him. “Oh, it’s ok. You did a good job teaching the foals how to use the big potty, obviously you forgot how slippery the seat can be. But for now let’s just focus on the training potty, okay? I really don’t want any of you getting hurt, or worse.”
Dr. Whooves nodded and then cried as he felt his pull-up was now completely soaked in toilet water. Mrs Cake was quick to help take the soggy pull-up off, wrap him up in a towel and ruffle his mane, making him giggle.
The mare then pulled a new pull-up over his rump and Mrs. Cake came over and nuzzled him. “There, all dry and clean. And from now on, come get me if any of you have to go potty.”
The colt blushed. “Otay, tanks Mama… Mrs. Cake.” He squeaked and his face turned a bright red as the Cakes all laughed together at his slip up.
Mrs Cake then gave Dr. Whooves new dry pull-up a few pats, and then led him out of the bathroom.
Dr. Whoves had a smile on his face, he was actually kind of excited at the prospect of being a toddler for a few days. Though he shuddered at the thought of how much babying Pinkie Pie and Mr. Cake were inevitably going to subject him to as a result.
