Pipp Petals, the younger of the two pegasi princesses in Zephyr Heights, was silently cursing under her breath. She was almost two and a half years old now, and well on her way in potty training. Of course, her big sister Zipp who was about a year older was also in potty training, and much further along to boot. That wasn't the problem, however. No, the problem was that there was only one potty to share among them. Zipp had apparently progressed in her training far enough to where she was supposed to be using something else whenever she had to go.
But it seems that Zipp had thought otherwise this time. She said it hadn't been intentional, she'd just had to go really bad. But she'd ended up using the training potty that was supposed to be Pipp's and Pipp's alone. And it was still being cleaned. That meant Pipp had no choice but to use what Zipp was supposed to use: The toilet.
"It's not my fault I'm so small!" Pipp mentally grumbled as she hesitantly trotted along to the bathroom, her diaper crinkling with every step she took. She'd rather not have to use the almighty porcelain throne if she could help it. It was just so… big, and so intimidating. And according to Zipp, there was a monster inside of it that liked to eat foals. Of course, their mother was quite insistent that there was no such thing as a "potty monster". And their mother had been right about many other things, so she had to be right about that too. At least, that's what Pipp assumed.
Well, it wouldn't be all bad. Pipp knew there was something in the bathroom that could help her take her mind off her fears. Whenever she needed a burst of confidence, she could always turn to her countless fans: The Pippsqueaks. Many of them were apparently just as young as she was, if not younger. And as it so happened, she had set up a stand in the bathroom for her phone, making it easy to turn on and start streaming no matter when she had to go or what she had to do.
So it was that the pastel pink pegasus princess prepared for another potty training livestream. This one would be extra special, it was a stream she hadn't expected to start doing anytime soon. Alas, circumstances being what they were, she would have to do it now. After all, her mother had made it perfectly clear to Pipp that she was too old to still be having "accidents" in her diapers. Princesses did not pee or poop their pants, such behavior was unbefitting of royals when they were old enough to know better.
Taking a deep breath to steady her nerves, Pipp pushed open the bathroom door and waddled inside. Then she closed the door behind her so as to ensure there would be no unexpected guests coming in to interrupt her stream. Sure enough, the toilet was waiting for her near the back of the bathroom. And it seems that somepony had left the lid up, they had forgotten to put it back down.
Well, that made things easier for Pipp. She quickly pulled down her diaper, then waddled over to the stand on which her phone rested. She made sure its camera was facing towards her, not away from her. Then, she pressed a button, and commenced her stream as she saw a light confirming that she was indeed live streaming.
"Hey, Pippsqueaks," The pegasus princess greeted. "It's me again, Pipp Petals. And I've got a special treat for you all today. I'm going to use the toilet for the very first time. I know, shocking, isn't it? Well, I wasn't planning to use it, but a certain no good sister," She grumbled and briefly seemed to glare. "Decided to use my potty even when she wasn't supposed to. So if I want to be a big pony, I have to use the toilet."
Gazing back to the great porcelain bowl, the pastel pink pegasus couldn't help but gulp even as she tried to reassure herself. "I'm… not scared. Mom and Zipp use it all the time and nothing ever happens to them. I'm sure I'll be fine, even if I'm smaller than them. Wish me luck, Pippsqueaks." And with that, she turned her attention to the toilet as she prepared to mount its seat.
With a good deal of clumsy waddling, Pipp reached the toilet. She struggled to grasp the edge of the seat and hoist herself up so that she could sit down on it properly. Why did it have to be so big? Why couldn't it be more her size?
Well, Pipp was not a pony who gave up at the first sign of trouble. No sir! Pipp Petals never gave up! She wasn't about to let this great porcelain contraption get the best of her! And her efforts were finally rewarded as she was able to stand on the tips of her hooves, jump up, and grasp the seat firmly. Then, after maneuvering around a bit, she got herself into the proper position to use this big potty, and sat down.
The pastel pink pegasus princess' spring bud green eyes then focused themselves on her phone's camera, making sure it was still recording. It was, which meant she had an audience to celebrate her achievement with. "I did it, Pippsqueaks! Aren't I incredible?! This is easy!" She boasted.
Of course, now came the hard part of actually "going". That was always something Pipp found difficult, even when she had things like this livestream to keep her distracted. But she knew she had to try, so Pipp just sat there and sheepishly blushed. "Sorry, Pippsqueaks. This may take a while. Just be patient. I know I have to go."
It seemed like minutes passed before Pipp felt something move within her as her tail hiked up. Soon, she heard a series of plops and splashes, and a familiar stench reached her nostrils. She knew what that meant. She proudly raised her hooves into the air as she joyously proclaimed. "I… I did it, Pippsqueaks! I actually did it! I was able to use the toilet like a big filly, just like Zipp and Mom! Oh, I can't wait to tell them this! They'll be so proud of me, I know it!"
Yet as she became wrapped up and fixated on her accomplishment, Pipp didn't pay attention to where her hooves were. That is, until she felt one of them touch something cold and metal. Whatever it was ended up being pressed down by accident, producing a faint click. Then, suddenly, there was a great roaring sound!
Despite knowing that the roar was just the sound of the toilet's flush cycle starting, Pipp was nevertheless spooked by how loud it was! It had never sounded this loud before. And because of the loud noise, the princess ended up losing her balance on the seat. She fell backwards, falling into the bowl with an audible splash!
There was worse to come, because the flush cycle was already underway when Pipp fell in! She struggled to poke her head up above the spinning, rancid, rapidly draining waters in the bowl that were throwing her one way and then another! Faster and faster she spun, to the point where she couldn't see straight! "Zipp! Mom! Somepony! Help!" She cried, hoping to be overheard somehow! But nopony came.
Instead, as the flush cycle ended and took everything with it, Pipp felt a powerful suction take hold of her by the tail. And try as she might, she couldn't escape its pull. Before she knew it, she was being sucked down the drain! She disappeared with a garbled cry of "Glug, glug, glug!", all the while her perilous plunge had been captured live for all to see!
Just after the flush cycle ended and the toilet had refilled, however, somepony did come into the bathroom. That somepony was none other than Zipp Storm, who thought she'd heard noises. Yet as she looked around the bathroom, she could see no signs of anypony having been in it. All she could see was a discarded diaper that had been left on the floor near the toilet, and a phone on a stand that was still recording.
Zipp groaned in annoyance. "Seriously, Pipp? You have to livestream everything?" She proceeded to shut off the phone, thus abruptly ending the stream. Then, as she rolled her eyes, she put the diaper in the trash can and put the lid of the toilet down. She had no way of knowing what had just transpired, no way of knowing that her little sister was bound for the dark, dingy sewers of Zephyr Heights.
