The ride was only just beginning when Flurry Heart was flushed down the drain! Down, down, down she went on what was a very frightening water slide! Soon, she had disappeared through the hole in the toilet and plunged into the cold steel of the pipes, unable to escape as the water carried her along on its journey to... wherever it went when you flushed the toilet..
Everything went dark, the foal couldn’t see where she was going (or even where she had come from). Often, she would be tossed in one direction very suddenly, as the pipes changed direction on her several times.
All the while, Flurry kept screaming, yelling and crying, hoping that somepony would hear her and would get her out. Her mommy had been wrong, you very well could go down the drain! Needless to say, poor Flurry now knew the hard way that you had to be careful around the toilet. She most certainly wouldn’t play around with the flush anymore, assuming she ever escaped from… wherever it was she was going. There had to be an exit at some point, right?
At last, light began to flood the foal’s vision! This was it, a way out! The light was fast approaching, and the foal braced herself for whatever was to come!
Suddenly, with a plop, Flurry dropped out of the pipes. Her padded posture promptly plopped down into murky, foul smelling water with a splash. It smelled awful! It was like her dirty diapers before they were changed, but far, far worse! Of course, she should’ve expected as much when this was where ponies’ pee pees and poo poos ended up. But that didn’t make the stench any more tolerable. Now she understood why her parents made those funny faces whenever they changed her diapers, and why sometimes the bathroom smelled so bad.
To make matters worse, the toddler alicorn’s diaper was fast filling up with the murky, foul smelling waters and was now beginning to sag. All that work to keep her diaper clean earlier, and now it might as well have not mattered at all, she might as well have just gone pee pee into it. It was uncomfortably wet, heavy, and squishy (not to mention it smelled really bad).
Flurry Heart tried to stand up, hoping to at least keep her diaper from getting wet any further. But the weight of her sagging diaper, combined with the overall depths of the nasty water prevented her from doing so. In fact, it just made her fall back down, further submerging her backside into the muck!
Looking around, the little filly could see what looked like bricks. Not the kind of colored, plastic bricks she often played with, these bricks were drab and looked very worn. Strangely, she could also sometimes see what appeared to be ladders. And vents could be seen too. Did ponies sometimes come down into this place? Did ponies live down here for some reason? Who would ever want to live in a world that smelled constantly of pee pee and poo poo?
The alicorn foal and heir to the crystal throne didn’t know. If she ever got out of here, she probably wouldn’t want to find out. She just wanted to get back home to her mommy and daddy, and be safe and secure once more in her crib! This all felt like a bad dream, but it was far too real to be one.
Unable to find a way out, the only thing the flushed foal could do was float along and follow the waters. She wasn’t anywhere near strong enough to fight against the pull of the current, and even if she could she didn’t know where she could go. Her wings couldn’t possibly handle the added weight of her filled up diaper, and neither did she believe she had the magical strength to pick herself up. Teleporting was also out of the question, she had no idea where she was or where she would go. She was probably far, far away from the castle she lived in with her parents. Maybe she wasn't even in the Crystal Empire anymore.
So Flurry Heart floated along for mile after mile, hoping that wherever these waters lead it was to a place where she could get out and get back home. Her mommy and daddy were surely starting to worry about her by now, assuming they had woken up and checked the bathroom, where they were sure to find her full training potty (among other things).
Then, up ahead, Flurry’s eyes beheld a truly terrifying sight! A huge, spinning thing was fast approaching! The waters were flowing through it pretty easily, but she doubted she would be as lucky! That thing would surely slice and dice her to pieces if she didn’t do something fast! But what?!
Frantically, the frightened foal tried to fight against the pull of the curtain, hoping to break free and escape before she could be pulled anywhere close to that spinning thing! Despite her best efforts, however, it was a losing battle as she came nearer and nearer to the sharp blades!
Just as the little filly had resigned herself to her inescapable fate, she felt something move within her. Or rather, down her. It was her diaper! It had sagged so much it could no longer stay on. It slipped off her rump and flowed out ahead of her, bobbing up and down like a cork. When it reached the spinning blades, it did not get sliced into pieces as Flurry had been expecting. Instead, the super soggy padding wedged itself between the two blades! Just like that, the spinning stopped. And when the spinning stopped, so did the pull of the current.
Flurry’s diaper had saved her! “You the best, diaper!” She cheered! Never again would she take the padded undergarment for granted, even if she did still want to be a “big filly”.
A moment later, Flurry Heart’s ears picked up the sound of something being moved. Something heavy. She could also hear voices, albeit unfamiliar ones. And it sounded like they were saying something to each other. In addition, a faint trace of light could be seen a ways away.
“Yeah, I think I see the problem,” A gruff sounding voice called, echoing across the narrow confines of the structure. “Looks like somepony flushed a diaper, probably a dirty one from the looks of it.”
“Hey, is that a doll I see?” Another voice spoke up. “Who would flush a doll down the toilet? Don’t ponies know toilets are expensive to fix? Were they trying to clog up the entire sewer system or something?”
Flurry didn’t know who those voices belonged to, but they sounded friendly enough. With her soggy, saggy diaper no longer weighing her down, she was free to flap her wings and approach the location where the voices were coming from. She was saved! These ponies would surely take her back to her parents.
Two crystal ponies blinked in surprise as they were suddenly and unexpectedly greeted by the foul smelling presence of the heir to the crystal throne. “Hey, wait a minute,” A green coated crystal pony with ruby red eyes spoke up. “Flurry Heart? What were you doing down there? Don’t you know the sewers are not a playground?!”
Flurry whimpered as she apologized. “Me sorry. Me go down the toilet by accident. Me no mean to get flushed.”
A dark purple coated crystal pony with amber yellow eyes shook his head from side to side. “Kid, everypony knows it’s impossible for ponies to get flushed down the toilet. I don’t know what you flushed into the sewers or why you went into them, but it’s a good thing we found you when you did. I just hope you didn’t break anything.”
The green coated crystal pony then sniffed and gagged. “Ugh! We should probably give you a bath first! Oh dear Celestia, and I thought my nephew’s dirty diapers were bad! They’re nothing compared to this!”
Flurry’s face flushed fiercely. Still, at least she was relieved to be out of… whatever that place had been. Perhaps she hadn’t imagined her daddy going down the drain after all. If so, she owed him an apology for sending him to such a foul smelling place as this.
