Daring Do found herself slowly trotting through the thick foliage of vines and bushes, making it difficult to trek through the Tenochtitlan Basin alongside a mysterious-looking unicorn leading in front of her. She was a tall unicorn with a buttery yellow coat, a relatively long horn, and a wavy crimson mane flowing down her neck. The mare was wearing a trench coat and a hat making it difficult to distinguish her other features like her cutie mark. But she had a rather long snout and piercing green eyes.
The pegasus had told Daring about a map that led to an ancient pool she hadn't heard of before.
Daring Do had done a ton of research and uncovered many treasures in the valley. So hearing that there was a pool of water that allegedly gave you immortality sounded absurd to her. Yet…the map she was given was accurate to the language of the ponies who made up the ancient civilization that used to live in the valley. But there was a question she had never really thought about asking until now. The adventurer then looked up and asked her guide. "So, how did you come across this map, exactly?"
The mare turned around to face Daring Do as she placed a hoof to her chest and said, "Oh, just found it lying around the house, I am concerned with the safety of Equestria, and we should ensure that this pool doesn't fall into the wrong hooves."
"Right…" Daring growled, already feeling that the mare was acting and lying to her. The adventurer didn't trust this mare further than she could throw her as she didn't even know her name. But the map was technically hers, and the pegasus had transcribed it for Daring and volunteered to escort her to the pool. But the second she inevitably found out this mare was going to betray her, she'd be ready.
The two eventually made it to a clearing and suddenly stood above a massive water pool. The crystal blue waters were the clearest, pure-looking water Daring Do had ever seen. The pool was so beautiful and smelled so sweet, like a light drizzle of rain on a spring morning mixed with flowers and fresh grass. Daring Do was so memorized by the pool she didn't notice the mysterious mare behind her push her right into the waters below.
Daring coughed and gagged as she flapped her wings and struggled to stay afloat as she shouted! "What the buck?!" The adventurer tried to fly but couldn't. She instead clambered out of the pool and felt her body shrink. It was sudden as the pegasus started to become smaller, her favorite Sola Topee falling over her head. She threw it off her face and looked up to see the jungle around her becoming much bigger and the mysterious mare growing taller. She looked up and saw the mare just laughing.
"So much for the Great Daring Do! That was so easy!" The unicorn then dropped a bag on the ground as she continued. "Thank you for helping me find the pool, but I can't have you telling anypony about it. Especially not the princesses."
Daring Do wanted to tackle her, but as she ran, the mare could see her stubby limbs were less coordinated as she stumbled about. The pegasus eventually plopped onto her flank and looked down at her body. She saw it was much chubbier with her tiny, flabby limbs. Then it came to the adventurer that she didn't just shrink; she'd regressed in age! This pool didn't turn you immortal; it turned you into a baby!
As this realization dawned on Daring Do, the mare chuckled as she laid the foal down. Daring Do flapped her wings, kicked, and whined while trying to fight the mare off. But the mysterious pony continued to strap her up in a diaper, tucking her tail through the leg hole of the padding as she cooed. "Now, Daring, you don't want to have an accident, do you? It'd be a shame if you made Daring Doo-Doos all over the place."
Daring Do fought and cried, trying to stop the mare from putting her in such an embarrassing garment. But she was helpless to fight back as the mare finished diapering her, making sure the tabs were snug on the landing zone. Daring kicked about, hearing the diaper crinkling around her flank and feeling the soft material hugging her body. It did feel nice, but the diaper was a bit too babyish for her tastes, seeing that the padding had cute little light blue clouds printed on the padding.
"It's Cloudies, one of the best diaper brands money can buy. As much as I want you out of the way, I'm not evil," The mare then strapped Daring Do in a foal carrier around her chest and ensured the diaper was snug. "Don't worry, I've cared for babies. Two rambunctious colts, in fact. So you'll be well cared for until I feel it's appropriate to turn you back to an adult."
Daring Do kicked about and tried to fly, but she was securely strapped into the foal carrier.
The mare hummed a tune as she carefully collected a few bottles and water.
The little pegasus saw that this mare would use this water for some nefarious means. Daring knew she had to stop the mare, but seeing her new baby body, Daring realized it would be rather tricky. Daring then saw the straps were looped through a ringlet around where she was held. She only had the chance to untie this foal carrier without this mare noticing.
So Daring went to work, using her stubby hooves to work the straps. Eventually, she could unlatch it, causing Daring to fall onto her padded seat. She then waddled off as fast as she could (while grabbing the diaper bag nearby, just in case) and ran into the jungle.
After what felt like forever running through the jungle with a diaper bag around her, the filly's cheeks were red from having a diaper wrapped around her flank. Then again, it's not like she had never worn diapers before. On occasion, she had worn them just in case while exploring old ruins. But most of the time, she'd just answer nature's call in nature itself.
Daring panted and wheezed while looking around her, ensuring she wasn't followed. But now, the little adventurer was all alone in the jungle. Despite having explored this region for years, being alone in her young baby body, Daring Do was now scared and worried about what she should do! But then she heard something in the bush, making the filly stand up on all fours and shout. "Who's there?!" Nothing answered as she stared at the bushes.
Then rather suddenly, something pounced on her Daring looked up to see what it was that made her shocked. The creature was a kitten with a dark blue coat and a light blue undercoat. It had dark green eyes with black slitted pupils, the little kitten laughing as it exclaimed! "Got ya, Daring!"
"Ahuizotl?! Is that really you?!" Daring laughed, unable to control herself.
"Shut up!" Ahuizotl shouted.
The kitten got off Daring as the little pegasus asked. "Well, I assume ya followed me, right?"
The kitten scoffed and snapped. "Of course not! I found an old map my mother had about a pool of immortality. I didn't know it was gonna turn me into a kitten!" Ahuizotl then eyed Daring and asked. "How did ya end up as a baby?
Daring Do pouted, feeling rather stupid trusting a stranger; maybe her time with Rainbow Dash had made her lose her edge. She then looked down and grumbled. "Just found a map too and was gonna protect it from being used for evil."
Ahuizotl smirked. "Ya got tricked, huh?"
"Otay, yes, I got tricked." Daring snapped. "But it is not wike I wasn't expecting it."
"Whateva wets, just figure out how to turn back to adults," Ahuizotl grumbled.
"Ya wight, but there's something we need ta do first." Daring sighed as she brought the diaper bag and took out one of the padded squares.
Ahuizotl jumped back and shouted, "Oh no! Ya ponies may use diapers, but we cats use litter boxes!"
Daring threw her hooves up and shouted! "Look around ya! Do you see any litter boxes?!"
Ahuizotl hissed at her. "Ya stand back! I'm not wearing that thing!"
Daring then jumped on top of him as the kitten struggled and hissed at her, but she shouted. "Ya want to run around diaperless?! Ya wana go potty all over ta jungle?!"
The kitty Ahuizotl stopped fighting for a moment, seeming to blush as he thought about it, then eventually grumbled. "Fine…" he then laid down as Daring Do diapered him up. The diaper was designed for ponies, but it seemed to fit well enough over Ahuizotl's flank. She got off the kitten as he waddled about getting used to the padding.
Daring Do couldn't help but giggle seeing her nemesis looking so adorable. "So, ya wike being in diapers?"
"Shut up!" The kitten shouted back. "Just tell me how ya gonna get us back to normal."
Daring Do tapped a hoof to her chin, thinking things over. "Otay here's ta plan. I made a copy of ta map and other tings we'll need. But I left them at my place," The foal took out a compass that the mare had put into the diaper bag and said. "It'll be a few days, but if we follow my compass, we gonna get to my home."
"Ten what?!" Ahuizotl asked with a pout.
Daring Do lowered her head and sighed, seeing she was going to need help, and said, "Ten, we write a letter to Rainbow Dash and have her help us. I dun know if we can still wight wike tis, but I gonna draw a picture to get her to know we need help. Ten, we find a way to turn back to adults, deal?"
Ahuizotl grumbled under his breath. "Tat doesn't sound wike a plan."
Daring sighed. "It's not. If I'm being honest, I'm scared. We babies in ta jungle with all kinds of beasts. We gotta be careful. And ten, even if we get home, I gotta somehow get Rainbow Dash to come by ta help us," She then held out a hoof and said. "Despite being enemies for years, we gotta work togetha if we want to have a chance at turning back to big ponies."
Ahuizotl eyed Daring Do, not fully trusting her. But he looked around the jungle, and that same fear she was feeling, he was feeling too. The kitten gulped, held out a paw, and shook her hoof as he said. "Otay, we work together until we turn back to normal. Ten, we back to enemies."
"Fine, whateva," Daring grumbled as she took out her compass; she then started to trek through the jungle alongside Ahuizotl, who grumbled. "Ya better not write a book bout tis."
Daring Do looked back at her thick diaper around her waist, feeling so embarrassed at the thought of her readers seeing her like this as she replied. "Trust me, when tis is over, I gonna try pretending tis never happened."
