Double Diamond had no idea what to expect or anticipate when he agreed to investigate a possible disturbance up in the mountains surrounding the village he’d come to call home. It had been only a few months since it had been liberated from the control of a unicorn mare who had run the town with a not so secret iron hoof by forcing all the villagers to give up their cutie marks. She’d claimed it had been for the sake of “equality”, but Double Diamond suspected it was something more than that, some kind of resentment towards cutie marks.
Whatever the reason beyond that idea of stripping other ponies of their marks was, Double Diamond was glad it had been stopped. But a small part of him held out worry for Starlight Glimmer, the pony he’d once served as second in command. He didn’t regret turning on her, in fact he wished he had done it much sooner. But he wondered if perhaps he and the other villagers should’ve stopped to ask why Starlight hated cutie marks so much, and if there was something that they could’ve done besides letting her run away.
Apparently aware of this concern, fate was about to intervene in the most unexpected of ways in order to grant the ski loving stallion the opportunity to get some answers to those nagging questions of his. As he rounded a corner near the very maze of caves into which Starlight had retreated, the stallion with a powder white coat the same color as the snow around him saw a sight that almost stopped his heart!
There was Starlight Glimmer, her unmistakable grayish-purple coat and two toned purple with grayish aqua blue streaks mane and tail standing out in stark contrast to the drab landscape around her. In the glow of her horn she held what appeared to be a scroll of some kind. “Incomplete?” She muttered to herself. “That will never do! I’m sure I can find a way to modify this spell to suit my needs. And then I’ll make that pesky princess pay for ruining my life!” Her horn started to spark rather ominously as she focused on the scroll, and the spell contained within it.
Without hesitating for even a second, Double Diamond lunged forward and attacked the mare head on! He wasn’t about to let her get away with… whatever it was she was going to do!
The mare yelped in surprise as she was tackled, her horn shooting off a blast of magic as a result!
What happened next, no one knew for sure. But there came a poof and then as Starlight slowly stumbled to her hooves she saw only a small, white coated foal with an even smaller wisp of powder white for a mane and tail before her. “Double Diamond?” She blinked in confusion. “Just what the hay is your problem? Now look what you made me do!”
Double Diamond started crying uncontrollably. “I had to stop you! You were being a big old doo doo head! Now change me back! I wanna be a big pony again!”
This made the mare gulped. “Well that might be a problem because...” The next words left her mouth very slowly and in a very nervous tone. “I’m not sure how.”
The foal gasped as he continued to cry! “What do you mean you don’t know how?” He whined. “It was that stupid spell you had that turned me back into a foal!”
“I didn’t get a chance to perfect it or anything close to that. I was about to test it out for the first time when you so rudely interrupted me,” Starlight hissed. “See what happens when you mess with things you’re better off leaving alone? Now you’re back in diapers and I have no clue how to fix it. It could take months!”
The little earth pony just whimpered as the crying slowly stopped. “But I can’t stay stuck like this. You need to get help!” He protested, before a more urgent matter drew his attention. “Um, Starlight? How good are you with diapers?”
Starlight quickly realized what Double Diamond was trying to tell her with that comment, and immediately her eyes went wide! “Oh no! You can’t do that now! I don’t have any way to change you or clean you up! Can’t you hold it?”
“I don’t think I can for much longer!” Double Diamond protested.
Starlight had to resist the urge to groan and curse at her bad luck, it wouldn’t make the situation any better. Instead, she quickly settled on an idea as she trotted over and scooped up the foal she was now responsible for. “Well, can you hold it for a minute or two, or maybe three? I can take you someplace where we can be safe and I can get you some ‘supplies’ until I figure out how to fix all of this.”
“Do whatever you gotta do, just hurry!” The foal whimpered, squirming all about. It was so hard to use what control he had and not release into his diaper right then and there!
A quick flash of the horn brought Starlight (with Double Diamond in her hooves) to a very familiar location and one to which she wished she were returning to under better circumstances. Alas, she didn’t have the time to really lament being forced to come back. She just immediately dashed to a small house in the middle of a community that looked like it was a cross between old buildings and new buildings, frantically knocking on the door.
A grayish purple coated stallion clad in a red shirt with a white collar and a yellow tie answered the knock. His brown eyes nearly went wide when he saw Starlight on the other side! “Pumpky wumpkin?” He blinked in surprise, as if he’d seen a ghost!
“No time to explain, Dad!” Starlight protested as she rushed through the opened door. “I need the bathroom, now! It’s an emergency!” She was glad she still knew where the bathroom in her old home was, and was relieved to see it was just as she remembered it when she entered into it.
Everything was happening too fast for Double Diamond to comprehend as he soon found himself being stripped of his diaper and floated onto a toilet seat that had just been exposed thanks to the lid being lifted all the way up! “Hurry, go!” Starlight instructed! “Don’t worry, I’ve got you! I won’t let you fall in!”
“Honey bun, what is going on?” The stallion from before asked as he entered the bathroom. “You sure have a funny way of saying hello to your old stallion after all these years.”
Double Diamond, for his part, was too focused on his urge to go to pay much attention to the conversation. His face turned red as he grunted and his tail hiked upward, soon followed by a series of audible plops and splashes as a familiar smell of manure filled the air. That had been far too close for comfort!
Starlight plugged her nose, as did her father who used the brilliant gamboge glow of his horn to pull some toilet paper from the nearby rack. “Your foal can use this to clean up if he’s done. And make sure you both wash your hooves afterward, and don’t forget to flush.” He instructed, before trotting out of the bathroom.
Starlight, meanwhile, turned her attention to Double Diamond. “Never imagined I’d be potty training you,” She then asked in an almost motherly tone of voice. “You’re done, right?”
Double Diamond nodded. “Yeah, I should be. But what is this place? And who was that stallion?”
While using her magic to move the rolls of toilet paper to clean Double Diamond’s flanks, Starlight explained. “That’s my dad, Firelight. This is my home. We’re in Sire’s Hollow. I came here because it’s the only place I could think of that would have a bathroom and would keep us hidden while we resolve this little… issue. I hope my dad still has my old foal supplies.”
The little earth pony whimpered. “Starlight, are you out of your mind? I’m a colt, not a filly! I can’t be wearing filly diapers!”
“Well next time, don’t get in my way when I’m practicing spells and stuff like this won’t happen,” The unicorn scolded in an almost motherly tone (it felt weird to consider Double Diamond her child, was it a side effect of the spell that had gone wrong?), before dumping the used rolls into the toilet bowl and pulling the handle to flush it all away. “Now come on, let’s wash our hooves and then we’ll plan our next move, okay? Be thankful my dad didn’t dismantle the toilet, he always preferred chamber pots for some strange reason.”
