"Where is everyone?" Fionna looked around the empty foyer, "We must have been in there for hours."

Cake grew big and picked up Fionna, "Let's go back to the treehouse"

MEANWHILE…

"That party was awesome!" Finn and Jake were walking home. "And that part with the train mystery, that was sick!" Jake rolled his eyes, "I know Finn, I was there."

They walked to the door of the treehouse and Finn opened it. "Well you've been using good manners" Jake noticed. "I've noticed that girls want a more sophisticated man. And I think I wanna get back into the dating scene." Jake sighed.

Suddenly, giggles came from upstairs. "What was that?" Jake looked around alertly. "Probably BMO" Finn started to climb the ladder to their bed room. Then the heard a female voice playfully shout, "Shut up!"

"Oh dang, someone is up there!" Finn jumped off the ladder and grabbed a sword, "Okay here's the plan."

MEANWHILE…

Fionna sat on her bed while Cake braided her hair.

"Hey Cake, why do you like messing with my hair so much?"

"I don't know, why do you like swords so much?"

"Good question, I-"

Suddenly, Jake stretched through the floor boards and formed a cage around Fionna and Cake. Finn jumped up the ladder and landed in front of the girls, "What are you doing in our house!"

"Your house?! This is our house! We've lived in it for years!" Cake pulled out Fionna's sword and gave it to her. Pointing her sword at Finn, Fionna said, "We're Fionna and Cake and this is our house! I don't know who you guys are… Unless… Are-are you the guys from the book? Finn and Jake?" Finn stared at the girl in the royal blue dress with long blonde hair in a braid who stood before him, "Y-you're Fionna and Cake? But that's impossible… C'mon Jake let's take 'em to Peebles."
