"Thanks. I'll go wait outside the rooms, then," said John, before heading back to the small hallway lined with doors to changing rooms. He idly thought about peeking in the rooms to find Carrie. She had went into a room before he did and still hadn't come out, so he wondered if she needed help with her costume.
As John debated with himself, one of the doors opened up and a large shape pushed out of it, only to get stuck in the door frame. He had to slap a paw to his new muzzle to suppress a snicker as he realized what it was; such a huge mass of glistening, grayish brown flesh could only be an obese hippo's rear end. His human side knew it wasn't nice to laugh, but the toon in him could barely contain itself as he watched the silly patron struggle to get their ridiculous body through the door. When he saw the hippo resorting to bracing their stubby feet against the wall on either side of the door to try and push their way out, John could bite his tongue no more and simply burst out in a toony laughing fit.
What John didn't expect was for the hippo's plan to actually work. With a creaking sound of splintering wood, the hippo's body suddenly flew out of the door frame and towards John, who's laughter gave way to a deer-in-the-headlights expression a split second before he was sandwiched between the floor and the hippo's derriere.
"They need to make these doors bigger!" huffed Carrie, balling up her hoof-like fists at her hips. "Right, John?" she asked, glancing around the deserted hallway. "John? Where did you go? I thought I heard you out here." Carrie blinked in confusion as she heard some odd stretching sounds and felt something moving underneath her. She turned her head around and looked back just in time to see John's lupine head emerge out from under her butt with a wet 'pop!,' followed by him gasping for (fresh) air.
"Oopsy~" said Carrie, putting her pudgy hands against her blushing cheeks. With a grunt, she began pulling herself up off the floor, revealing a perfect rump-shaped crater where she had landed. Once she was standing, she reached a hand behind her to grab John by the scruff of his neck before peeling the poor wolf off his body.
"Hey, John! A wolf, huh?" said Carrie, bringing the John's flattened form around to her front and giving him a few shakes like a bedsheet to help make him three dimensional again. "I decided to go for something a little different!"
"You don't say?" said John weakly, eyes still spinning in his head from his ordeal.
