Pound and Pumpkin Cake were quite relieved when Mr. Cake decided not to say anything to Mrs. Cake about their attempt at helping the toilet get better, or that they'd stolen from the medicine cabinet.
Hours passed by uneventfully, and before the twins knew it was time for bed. For Pound, tomorrow held the hopeful promise that the toilet would be fixed, while for Pumpkin tomorrow held the possibility that the upstairs toilet might have to go, and she was worried about what that would mean for her brother, and for her. "Unless a new toilet comes right away, how will Mommy and Daddy clean out my potty?" Pumpkin thought. "They have a toilet in their bathroom, but would they be willing to empty a full potty into it? And what if Pound decides to go back to using his diapers until the regular bathroom gets a toilet?"
Pumpkin wasn't the only one worrying about things, Pound was worried too. "What if my attempt at making the toilet get better only made it worse and makes it so that the toilet doctor can't make it better?" He wondered to himself. "Or what if all the things I did with it are what caused it to break down? I thought for sure I fished out my sister's pull-up when I accidentally flushed her, didn't I?"
Those worrying thoughts lingered in the fore front of the twins' minds, as they both went unhappily to sleep. Tomorrow was a day that both couldn't come soon enough, and a day that they weren't certain they'd like the outcome of. Either way, the toilet problem would hopefully be fixed by the time Luna's moon rose in the night sky twenty four hours from now.
Pound woke up with a start, his body was telling him that he had to go and go badly! This was the first time he was aware of such a thing, as he'd previously slept through the night without any trouble. If he went, he was never aware of it and was usually changed promptly. And if he didn't go, he was always placed on his potty first thing in the morning. But he'd never done it at night, or on his own before!
But for reasons he couldn't explain, Pound didn't want to go in his diaper! Something inside him was compelling him to use his potty like a big colt! "Since when did I care so much about not using my diaper?" He thought to himself, then he wondered. "What if this is my sister's doing? What if she somehow planted an idea in my head that I wasn't aware of?"
Pound shook his head, he could worry about that later. For right now, the urge to go was quite strong and the more he hesitated, the more likely it was that he wouldn't make it!
Just like when he'd intentionally been trying to avoid using his potty, Pound flapped his tiny wings to get out of his crib and head towards the bathroom, and just like that occasion he only had enough strength to make it past the bars before he was forced to land on his diaper. But although he could've easily given into the urge and released then, Pound refused to do it. "I gotta do my pee-pees and poo-poos in the potty like a big pony!" He thought, quickly picking himself up and marching his tiny hooves down to the bathroom.
Pound was hoping his eyes would adjust to the darkness by the time he reached his destination, and they did just a little. But only to the point where he could see the shape and look of an object, and not the color. That was a bit of a problem, as he pushed open the bathroom door ever so slightly and made his way inside.
The urge to go was increasing with each passing second, Pound knew he needed to find a potty and fast! Fortunately, he soon spotted two small bowl shaped objects near the toilet, but unfortunately in the darkness he had no way of telling which potty belonged to him and which one belonged to his sister. He tried to rack his brain in the hopes of remembering where his potty usually was, but it was too busy focusing on the signals his body was sending him. Nature was calling, and if he didn't answer it soon it would answer for him!
Deciding that he couldn't wait any longer, Pound made a mad dash towards the closer of the two potties and after clumsily stripping himself of his diaper, he sat down in it, just in time! His tiny body could hold back no longer! With very little effort, Pound was able to hear the sound of something tinkling and plopping into the potty, and he felt incredibly relieved! It was then that something else washed over him, a feeling of pride! Yes, that's right, for whatever reason something inside him felt good for recognizing that he had to go, and doing it in a potty instead of a diaper. That just left the question of who's potty he had used.
Pound didn't have to wait long to find out, all of a sudden the bathroom light flickered on, and there stood Pinkie Pie! Was it Pound's imagination, or was she giggling?
"Ah, Pound Cake, I know you and your sister like to share a lot of things but I didn't know she gave you permission to use her potty!" Pinkie said with a giggle, barely suppressing plenty of chuckles with a hoof.
"Wha you mean-" Pound began, before he looked down and saw what color the potty he was sitting on was. It was pink, and he knew that meant. In the darkness, he had mistaken his sister's potty for his own and had used it. Whoops!
Pinkie continued to giggle, as she made her way over to Pound. "It's okay, Maud did the same thing as a foal. She mistook Limestone's potty for her own, Limestone got pretty mad and used Maud's potty as an act of revenge."
"Pinkie, pwease dun teww Pumpkin." Pound pleaded, terrified beyond belief at what his sister would do if she found out about this.
"Relax, my lips are sealed," Pinkie replied. "Now, let's get you cleaned up. And you wanna know something? After that impressive display of potty training mastery, I think you're ready for pull-ups!"
