"Cake!" a high pitched scream evacuated a ten year-old girl's smiling mouth

"Cake! Cake! Cake!" the girl called, running down the wooden stairs to the small kitchen, "Cake!"

"What is it, sugar?" Cake, the girl had been calling for a few seconds, asked as she came in to view from the living room

"Gumball asked me for a sleepover tonight." the girl excitedly announced

"Mhm, who will be coming?" the yellow and white feline asked

"Gumball said that it would only be me, him, and Marshall." The girl politely answered

"If it's only you and Gumball, I'd allow you anytime, but with Marshall, no."

"Aww, Cake." The human whined, "But everybody will be there."

"There's only three of you." The cat stated as a matter of factly

"Exactly." Fionna the Human answered

The cat sighed, "I guess I could trust Gumball and Peppermint Maid."

The girl's smile jolted back in her face.

"My first boys' night!" The girl squealed and started running back to her room

"Wait, boys' night?!"

-

"There Marshall." A fourteen year old pink prince said as he put a hot pink phone down, "Fionna's coming."

The eighteen year old smiled triumphtantly. He laid back on the pink couch the prince had in his room and the teenager sat down on his bed.

"Let's get things straight Marshall." Gumball started, "Fionna, she's ten years old. Ten! T-E-N! Ten."

"Right, right, I know my numbers." Marshall rolled his eyes with a light chuckle

"Marshall this is serious. She's as innocent as a little feather and I do not want her to get corrupted in my sleepover." Gumball groaned, "You know how Cake is."

The boys shuddered at the thought of the human's sister scratching their faces, arms, legs, chest, and all the other parts reachable by the cat.

"Alright, I'm obeying you, only because I don't want my ridiculously handsome face to get destroyed." Marshall smirked

"Good. Now since Fionna's a girl," The prince continued as Marshall's eyes went wide, "I think we should avoid topics that only boys should discuss, you know what I mean?"

Marshall kept a startled expression on his face, "Fionna's a girl?"

"Ugh! Honestly!"

"No, dude I'm serious! Fi, the person I've spent, I dunno, a year with is a girl!" Marshall pointed out, floating in the air wildly

"We all know that, Marshall." Gumball said with his arms crossed

"Except me! When did she become a girl?" The vampire asked

"Ever since she was born." Gumball answered sardonically

"Well that explains her always wearing a skirt." He sat back on the chair

There was a light knock on the prince's door and both royalties looked at it.

"I think that's Fionna." Gumball said

Marshall and Gumball went to the door, either floating or walking. Gumball opened it and saw the human and her sister.

Marshall eyed the girl. She was wearing a long blue sweater that reached her knees with the words 'Boys' night' written on the chest part, with some letters written, not so properly. The sleeves of the sweater covered her whole arms and four inches excess space, showing the fact that the garment was not hers. She had her plain white socks on that reached three inches under her knees showing a little too much skin for a ten year old.

"Hey Fionna, Cake." Gumball greeted

"Yeah, so tell me Cake, is Fionna wearing her skirt? Or shorts perhaps?" Marshall cautiously asked

Cake glared at the floating vampire, "Gumball, keep Fionna, as far as you could, away from Marshall."

"Hey!" Marshall crossed his arms, "I know that I have a reputation but

Fionna is ten!"

He paused for a while.

"Maybe when she's older." He muttered, lucky that the cat did not hear it, "Still, you're not answering my question."

"She isn't." Cake answered angrily

Marshall muttered something inaudible.

"Um, Marshall," the little human squeaked

"Wha-. Why?" the 999 year old vampire asked

"Your, um, nose is..."

Marshall put his right hand to his nose and noticed the slight wetness. He looked at his now wet hand and his eyes bulged at what he saw. His right hand's fingers were now slightly soaked with red blood from his nose.

"What the" Cake glared a warning to him, "junk!"

Marshall rushed to the bathroom the prince had in his room.

It was going to be a long night...
