Anais was outside the bathroom, holding her crotch and moaning in pain. "Ohhhh...come on, mom! I seriously gotta go!" Anais began doing the pee dance, trying to hold in her urine as Gumball and Darwin walked by, glancing their sister dancing.

"Dude, that looks like fun!" Darwin elbow bumped Gumball.

"What kind of dance is that?" Gumball asked.

"I'm not dancing! I just really gotta go! And I can't hold it any longer!" Anais groaned, a worried expression on her face.

Gumball's face lit up. "That looks like an awesome dance!"

"And stupid too! Let's do it!" Darwin claimed, before he and Gumball began doing the pee dance along with Anais, whose bladder was in too much pain for her to feel annoyed about it.

"Oohhhh!" Anais groaned as she felt a puddle of urine form under her, yellow liquid leaking out of her panties. "No! Not this again!"

A few moments later, a toilet flush was heard, and Nicole opened the door, sighing of relief as Anais stormed in and shut the door as quickly as Nicole stepped out.

"Boys, what are you doing?" Nicole asked them, noticing that they looked like they could explode at any moment, gawking at the puddle of urine near them, putting her hands on her hips. "Gumball! Darwin!" she fumed.

"That wasn't us!" Gumball stated. "We're just dancing for fun!"

"Yeah!" Darwin added.

Nicole gawked as she looked back at the bathroom door. "Well please stop it." she told her boys as she walked away.

Gumball stopped doing the pee dance, noting that Darwin was still doing it. "Dude, you can stop now. She's onto us."

Darwin frowned. "It's not that! I really have to go now!"
