Chapter 1:

House Call

Princess Bubblegum answered the castle door instead of the usual Banana Gaurds. Finn didn't think much of it, but Jake found this strange.

"Hey, PB," said Finn.

"Hello... Fiiiinn..."

"What do you need from us?"

"Yeah," said Jake, suspiciously, "and where are the Banana Gaurds? It's too quiet in here..."

Princess Bubblegum squinted her eyes at Jake, making him feel uncomfortable. A grin slowly spread across her face, and she giggled. She giggled like a mad woman.

Finn shivered, he was beginning to feel that something just wasn't right with the princess today. And had her lab coat always been so, red?

Princess Bubblegum breathed out and patted both the boys on the head. She turned around and walked ahead, waving her hand forward.

"Follow me to the incubation chamber."

The boys followed, and were led into a dark room, dimly lit by a large glowing dome. Jake clung tight to Finn, he had a bad feeling inside. As they neared the dome, a faint scent hit them.

Banana?

Princess Bubblegum whirled around in her lab coat and smiled wide.

"Come on! Before she shows up! I have something to show you!"

Finn and Jake exchanged looks, then moved closer to the dome and peered inside.

"Flowers?"

The boys were very confused. Princess Bubblegum didn't really called them to the kingdom just to look at a bunch of stupid flowers, did she?

"Ah, Bubbleg-"

"Shhh!" Said Princess Bubblegum. "She's coming!"

Finn readied himself for a fight, but the Princess took his sword away.

"No, you'll scare her!" She whispered.

There was a rustling outside of the door. Faint, quiet, loud, louder.

"Um, Princess," Jake said, "what's going on?"

He cowered helplessly behind Finn. Princess Bubblegum shushed him. A loud cackle sounded through the room, the vibrations bounced of the walls.

"I see you've been expecting me, Bonnie!"

The three of them huddled together and looked all around them.

"Amazing," said Princess Bubblegum, "she didn't even have to use the doors..."

"Look PB!" said Finn. "The window is open!"

Princess Bubblegum rolled her eyes and sighed.

"Oh my glob."

"What's with the fighting stance?" Called the voice. "There's no way you'll win against me... especially not while you're wearing... RED!"

Everyone screamed as Princess Bubblegum was thrown to the ground. Her red lab coat was turning white.

"Princess!"

Finn tried to approach her, but was stopped dead in his tracks when a large hairy bat materialized before him.

Jake fainted, but when Finn got a closer look at the monster, he just rolled his eyes.

"Marceline!?"
