The Mysterious Diaper Bag

by Zubric


Fluttershy and the Padded Wonderbolts

Pinkie raced across the bridge to Fluttershy’s cottage quickly moving to the front door and knocking rapidly. “Fluttershy, I need your help!”

A short scramble of hooves could be heard before Fluttershy opened the door tilting her head. “Oh, what’s wrong Pinkie, is something wrong with Gummy?”

Pinkie caught her breath before speaking. “No he’s fine, but Rainbow Dash might not be,” she replied lighting grabbing a hold of her friend's shoulders.

“Oh my, maybe you should come in and tell me, this sounds serious.” Fluttershy steps aside letting her friend rush in before heading to her kitchen and taking the cup she’d left on the table. “What’s wrong with Rainbow Dash? Did she get hurt?” she asked letting out a light yawn before sipping her black beverage.

“No, there's this magical diaper bag going around, and my Pinkie Sense says that Rainbow is next on the list.”

Fluttershy blinked tilting her head setting her cup down. “Um, did you say diaper bag?”

“Yeah, big and pink, and full of foal supplies, the works!” Pinkie shot her hooves into the air. “Made me wet the bed, and then Luna showed up and diapered me,” she added.

“That does sound embarrassing, but doesn’t sound too bad.” The passing thought of herself in a diaper crossed her mind causing a faint blush before she shook her head.

“But it gets worse, it is mentally regressed Spike and Twilight too. They think they’re toddlers!”

“Oh my, how can I help though? Rainbow is in Cloudsale practicing with The Wonderbolts.”

“Cause you have wings and I know you can get there faster than me with the hot air balloon.” Pinkie explained. “Help me Fluttershy, you’re my own hope.” She then blinked noticing what Fluttershy was drinking. “I didn’t know you drank coffee.”

Fluttershy peered down at her drink. “Oh, it’s decaf. I had a really early morning at the sanctuary.” She gulped down the last of it before standing up. I'll go check on Rainbow Dash, I don’t want her hurt from whatever that bag could do to her.”


Sweat covered Rainbow Dash's body being exhausted from a long day of flying practice. After going to the showers and taking one long hot steaming shower she came back to find her gym bag was replaced with a diaper bag. “What’s this doing here!”

“Rainbow Dash is that a diaper bag!” Spitfire exclaimed coming out of the shower seeing Rainbow’s face turned a bright red. The captain burst out laughing drawing the attention of Soarin as he came out of the showers and chuckled too, “Oh that’s adorable, did your mom give that to you?”

“No! I don’t know where this came from!” Rainbow cried, kicking the bag over causing plushies to spill out. There was a teddy bear, a stuffed rabbit, and a plush dragon. The Wonderbolts stared at the plush animals being unable to look away from them.

“I...we..well..um...I'll pick them up.” Rainbow Dash stammered as she began putting the plushies in the bag, but stopped once she had a hold of the dragon plush. It was cool looking with it being bright blue with yellow buttons for eyes. Spitfire shook her head and walked away feeling quite embarrassed for secretly wanting the bunny plushie.

“Um...R...Rainbow c...can I see the teddy?” Soarin asked, whimpering as his face turning a shade of pink.

“Oh..s...sure,” Rainbow Dash responded being a bit unsure of why Soarin would want such a foalish toy. She retrieved the plush for him and watched as he hugged the teddy bear nuzzling into its fur. Rainbow nuzzled her plush dragon too loving how it felt and it made her feel more confident.

Soarin looked behind him and asked, “something feels off? I...I feel like I need something around my rump but I can’t put a hoof on it?

Rainbow felt the same way nodding. “Yeah, me too I know how to go potty! But I need something on just in case, ya know?”

As she looked back toward the bag she saw something peeking out from it and pulled out a package of Wonderbolt style training pants. “Oh, these look nice! And their my size too!”

“Oh! Let me have one!” Soarin exclaimed as Rainbow Dash opened the package and pulled out two. She hoofed one over to Soarin who struggled putting his on more than Rainbow Dash. “uh Soarin I don’t mean to be rude? But are you ready for pull-ups?”

“W...well I gotta try to use the potty.” Soarin whimpered feeling a bit unsure if he had just started learning how to use the potty.

Rainbow Dash waddled over and assisted Soarin with his pull-up. “Well if you need help, just let me know okay?”

He nodded nuzzling Rainbow as Spitfire came over now having bows in her tail and mane along with a cute sparkling blue cheerleading uniform holding the stuffed rabbit under her wing.“Hey, you two can’t be alone unsupervised mommy would be so mad if you got lost or hurt.”

“Uh, who's mommy?” Rainbow Dash scratched her head.

Spitfire came over and checked their pull-ups as she explained, “I...uh...don’t know but she should be here soon?”

Spitfire nuzzled them and turned to Rainbow Dash. “So, I'm gonna practice my cheerleading, you wanna practice ballet right?”

“Oh yeah! My recital is next week!” The former daredevil pegasus cried out as she took out a baby blue tutu from the diaper bag and started putting it on.

Soarin feeling left out whined, “um..I...I need to practice something too!”

Rainbow Dash smiled at her baby brother. “Oh right! Uh…” she picked out a big foam soccer ball and a small plastic net. “Oh, you can play with this!”

“Oh, that's right! I'm in the junior soccer team! We got 0 out of a hundred we not so good.” Soarin giggled taking the soccer ball.

Spitfire rolled her eyes. “You don’t know math Soarin.”

“Yeah, I do! One plus one is two hundred!” he cried out.

Rainbow Dash snickered, “that was close! Let’s go practice!” she pulled on Soarin’s hoof as he cried out.

“But I’m not wearing anything!”

Soarin was stopped as Rainbow pulled a T-shirt over his head that read. “Cloud Butt” “There that’s perfect on you.”

“Nah, uh! I don’t wear diapers anymore!” He cried out like an angry little toddler.

“Soarin, you stop that! Now come on before I tell mama.” Spitfire snapped back making him stop as Rainbow Dash nuzzled him.

“It looks cute on you.” She took the diaper bag as they all walked out onto the Wonderbolt field together.

The other Wonderbolts all went home as Spitfire began dancing about waving her pom-poms while Rainbow Dash twirled around trying to perform ballet but was quite clumsy as she kept plopping on her bottom. Soarin kicked his ball around trying to hit it in the goal but he kept getting distracted soon enough sitting down and teething on the ball.

Fluttershy soon arrived fluttering down to the Wonderbolt’s stadium and saw it was empty. “I think they were doing practice this morning hopefully I’m not too late.” It wasn’t long until she saw the three Wonderbolts together baffled by what she saw. The captain of the Bolts was jumping up and down in a cheerleader costume, Rainbow was swirling about in a tutu, and Soarin was still chewing on the soccer ball.

“Oh no! They must have been affected by that diaper bag Pinkie told me about!” She flew over in a hurry but the second she came into their view they all shouted, “Mama!” and flew into her knocking her over.

“Eep! Uh, get off please!” Fluttershy cried out the ponies stepped back.

Spitfire replied, “sorry mama, we just missed you.”

“Spitfire, I’m no-” Fluttershy paused then remembered they’re under the diaper bag’s magical influence and that she might have to play along to find out where it was and to make sure they would stay out of trouble. “Ye..yes I’m your mother, now Spitfire can you um tell me how old you and your uh...siblings are?”

“Oh, I just turned eight!” Spitfire exclaimed clapping her hooves.

“I’m four and almost done with potty training.” Rainbow proclaimed proudly shaking her training pants some for emphasis

“I uh...three…” Soarin stammered and blushed turning his head to see his pull-up was yellow tinted. “Uh oh, sowie.”

Spitfire whined, “ugh! Why didn’t you tell me you needed to go potty?”

“Oh stop he just started potty training.” Fluttershy scolded Spitfire. “Now how um...long has he been in potty training?”

“Just started mama.” Soarin whimpered with tears coming to his eyes Fluttershy’s maternal side took over as she came over. “Oh don’t cry it's ok that’s what training pants are for. Now come along let’s all go potty before we leave.”

“Okay mama!” the bolts all cheered as they went back into the locker room as Fluttershy sighed, “oh dear it’s worse then I thought? I can only hope that we find that diaper bag and get them back to normal soon.”


Fluttershy assisted both Rainbow Dash and Soarin onto training potties that had appeared out of thin air. Spitfire waited outside the bathroom playing with her plush rabbit as Fluttershy came out she asked, “why do you three cling those plushies all the time? You haven’t let them go since I came?”

“It makes me brave! Rainbow Dash shouted.

“Yeah, I like my teddy.” Soarin nuzzled his plush animal and Fluttershy noticed that the plushies might have been what was making them act like foals. A low tingled echoed in the back of her head as she looked at them more.

“‘Well how about you come to my cottage for a snack then nap time?” Fluttershy asked, knowing they would at least be safer there than in the open.

Spitfire grumbled, “I don’t need a nap.”

Rainbow Dash snapped, “only if you watch me do ballet!”

Soarin was looking around the locker room not paying attention as Fluttershy giggled seeing how he was acting more like a foal then the others. “Well there’s no ifs, ands or buts you’ll take naps after snack time now come along can you fly by yourselves?”

Rainbow Dash and Spitfire fluttered clumsily but flew up while Soarin tried to but kept plopping on his bottom.

“Oh dear...do we have a stroller or something?” Before she could look around one appeared with blue and yellow stripes and little toys placed on the tray. She smiled. “Oh, perfect.” she settled Soarin in strapping him in and making sure the straps were snug. “There all comfy, now do you need anything?”

Soarin just hugged Fluttershy who nuzzled him back. A sense of pride washes over her. “ Oh, you’re just so cute.”

“I’m cute too!” Rainbow Dash whined getting jealous.

“Oh you’re so adorable Rainbow Dash especially in that tutu, I can’t wait to see you do ballet.” Fluttershy snickered as she planned to film that.

She took them by their hooves. “Now you hold on and don’t let go okay?”

“Okay mama,” the fillies replied. Fluttershy was a bit embarrassed being called “mom” but she did want foals one day maybe this can be practice. The idea became more pleasant the longer hse thought on it.

Fluttershy saw on the stroller handles a pink button and decided to push it watching as a pink fluffy cloud appeared under the stroller she shrugged and flew off with the fillies trailing behind.


Fluttershy was feeling more and more maternal as they flew through the air as she would stop to ruffle Rainbow’s and Spitfire’s manes constantly.

Once they landed at the cottage the yellow pegasus checked Rainbow Dash’s pull-up. “Hmm, all dry that’s good.”

“Hey! Don’t do that in public!” Rainbow whined.

Fluttershy came over and saw Soarin’s padding was yellowed again. “Oh dear...maybe he’s too young potty training.”

“Hehe back to diapees for Soarin.” Rainbow snickered as Spitfire rolled her eyes. “He couldn’t even hold it for ten minutes.”

“Now now, don’t tease your little brother there are peanut butter crackers on the table. You go ahead and eat up while I change Soarin.”

“Okay mama!” the fillies chimed rushing into the cottage Angel Bunny blinking as he watched them go.

Fluttershy unstrapped Soarin and lead him inside she noticed that somehow the floor was covered with toys while a playpen was set up in one corner along with a changing table and some training potties. She shrugged seeming to think this was normal and placed Soarin down on the changing table before going about removing the pull-up and putting a diaper around his rump with little Wonderbolts symbols printed on the padding. “There, some extra protection just in case.” Fluttershy chirped.

Soarin giggled and kicked like a foal seeming to be happy in his pampers.

“Oh, what a cute bunny!” The mare heard the fillies cry out.

Fluttershy gasped “wait don’t touch Angel! He’s quite fussy!”

She came into her kitchen to see Angel pouting crossing his paws as he was being strapped up in a diaper by the fillies.

“Hey! He’s not a doll!” Fluttershy scolded flying over. Although she did find it somewhat amusing. “Animals need to be treated with care. They aren’t toys.”

“Sorry, mama.” Rainbow Dash whimpered.

Fluttershy sighed. “Just be more careful.” She turned to Spitfire who seemed the most ‘grownup’ of the bunch. “Spitfire, where did you get the diaper and plushies from?”

Spitfire too out an odd diaper bag. “Found this! There was a package of diapers for bunnies.”

Fluttershy gasped seeing the diaper bag thinking it might be the one Pinkie Pie told her about. Her first thought was to take it and find a way to destroy it. But...it seemed to call to her having a feeling she needed it to care for these three foals. It’s what she wanted after all She held her head for a moment trying to focus finding a small resistance, but it wasn’t much as she was very tempted to keep going. It gave her so much joy.

Rainbow Dash gave the yellow pegasus puppy dog eyes and asked, “hey mama want to watch me do ballet now?”

Fluttershy blinked slowly nodded, ‘Oh yes, show m-mama how you’re doing.”

“Yay! Just watch!” Rainbow Dash exclaimed as she began to twirl about clumsily. Fluttershy watched thinking that the filly’s performance would be cuter if the tutu was pinker with more frills.

Rainbow Dash finished by trying to leap in the air only to trip and land on her bottom. She blushed but Fluttershy simply clapped her hooves. “Oh so talented I can’t wait for your recital!”

“Thanks, mama, need to practice some more that last part is hard,” Rainbow admitted slowly getting up.

“Oh don’t worry, you have a week left you’ll have plenty of time to practice, but do you want a prettier tutu to wear?”

Rainbow looked at her tutu and pondered it. “Oh! Uh…sure I wouldn’t mind a pink one?”

Fluttershy took a frilly pink tutu out of the diaper bag. This one having extra ruffles on the tutu making it much larger with all the layers. She helped Rainbow take her old one off before placing the new one over her friend’s body. “There, it's perfect it even shows off your pull-up more.”

“Thanks, I love it!” she bounces up and down making the frills fly everywhere while Spitfire was a bit jealous and asks, “can I have a cute new cheerleading uniform?”

“Hmm, let’s see what we can find,” Fluttershy cooed peeking her head int the bag. There was the sound of shuffling before she emerged once again with a yellow and pink cheerleader uniform. The skirt even had butterflies printed on it. It even came with some light pink socks to match. “Oh look, you can be mama cheer squad. Isn’t that nice?”

Spitfire cheered letting Fluttershy remove her old outfit before the new one was put in its place. The large tail bow remained on her dock as well. The captain stood on her hind legs and shook the pom poms about smiling. “Mama she the best, she can mother like the rest.”

“Oh that’s very nice, now let’s see what we have for little Soarin.” After a moment of digging she spoke. “Oh look I found a cute onesie for Soarin!” she pulls out a bright blue and yellow striped onesie that read “Wonderbutt” on it. “Oh, he’ll love it!” She helped place it over the stallion and buttoning up the flaps. “They’re perfect for a little foal.”

“Love mama.” Soarin giggled bouncing up and down with joy drooling a bit in the process. Fluttershy dawed. “Oh I found a pacifier too!” she popped it into his mouth seeing the Wonderbolt insignia on the front. He suckled on it looking at it cross-eyed.

Rainbow asks, “hey mama? Can you tuck us in now I tired?” she yawns.

“I want to take a photo of you three first okay?” She mothered recovering a camera from a nearby shelf. “Line up in a row please.”

They all lined up in their new outfits while Rainbow had Angel still in his diaper on her head.

“Oh no pouting Angel, I’ll take it off after the picture.” She waited a moment before snapping a few photos having them take various poses before finally putting the camera down. “Okay, now it’s your nap time no buts.”

Taking the three up to her bedroom, she laid Spitfire and Rainbow Dash in her bed which now had rails for safety while Soarin had a cradle with a mobile full of clouds and lightning bolt.s She was beaming ear to ear as she began to sing a soft lullaby to the three swaying gently on her hooves. The pegasus felt so happy as she did just like any proper mother would. It was like playing out her fantasy, but it was really happening.

She couldn’t help but check Soarin’s diaper one more time seeing it was already soaked. “Oh, good thing I put him in diapers...I probably should put Rainbow Dash in diapers too...”

The mare turned her attention to Rainbow and slowly took her pull-up off and strapped her in a Wonderbolt printed diaper like Soarin’s. “There, you can never be too careful with foals. Don’t want soaked sheets later.”

She dawed seeing Rainbow Dash gently kick about in her padding and took out a camera for one more shot making sure the flash wasn’t on.

Fluttershy fluttered back downstairs, she made her way to her kitchen once more seeing there was still some coffee left in the pot from this morning. She poured herself a cup needing a break from mothering. As she waited for it to warm up, her attention turned to Angel who was now suckling a pacifier with a carrot on the shield. “Huh? Where did that come from?”

Once warm, she pours herself a cup and sipped the idea of Angel being cute fading as she became more concerned. “Wait! Why are you in a diaper!” The mare squeaked as her mind was flooded with memories of the past hour with her face turning pink. “Oh! The diaper bag! I can stop this still!” She turned the main room to see it was now gone leaving behind a few packages of Wonderbolt printed diapers like a calling card.

“Ugh, now it’s just being a meany! B-but wait,” she looked at her cup. “Coffee that’s it!”

She took a bottle and filled it with coffee before popped it into Angel’s mouth. He instantly glared at his diaper ripped it off and stomped on it.

“I need to go have Rainbow Dash and the other Wonderbolts drink this!” She flew upstairs but upon seeing the three sleeping so peacefully her maternal instincts kicked in. “oh...maybe after they wake up...I would love the look of Rainbow’s face waking up in that outfit! Payback for all the pranks she’s pulled on me on Nightmare’s night.”

“I’m going to tell Pinkie Pie that coffee is the cure!” Before she left the mare turned and snickered, “Sleep tight Rainbow don’t wake up until I get back.”
