So Jake the Dog and Finn the Human travelled back through the Land of Ooo. They trekked through the frigid tundra, tiptoed past the strange bird-like creature that looked like a rock and stopped to splash near the giant shell on the beach.

Eventually, they reached the treehouse. Home, sweet home. They burst through the front door exuberantly.

‘YEAH!’ they yelled together.

Their excitement soon turned to shock. They noticed that their treehouse had been invaded by slimy squatters. Weird worms inched their way across the floor, over the couch and past the cast iron stove! They stopped their wiggling and buzzing as soon as they saw Finn and Jake. Then they began to glow.

‘Did you guys get on the bed?’ Finn asked. ‘I told you. You’re not allowed!’

Just then, a giant Worm King slithered through the ceiling. He towered over Finn and Jake.

‘Oh, hey, guys,’ he greeted the pair of adventurers.

Finn and Jake just looked at him blankly.

The Worm King glowed with magic. He zapped Finn and Jake with two green beams of light that shot out of his eyes. The rays seemed to carry some sort of otherworldly mind control.

‘Come here, guys,’ he said. ‘Hug me.’

Finn and Jake had no self-control. They put their arms around the Worm King for a slimy hug.

Fortunately, being back in their own home gave them a certain strength – perhaps even enough to break the spell. Using all their powers, they slowly freed themselves from the Worm King’s grasp.

Jake picked up his violin. Finn cleared his throat. Yes! They would raise their voices in song to reclaim the treehouse from the worms.

‘Home is a place,’ Jake sang. ‘Home is where you keep all your best stuff.’

‘Yeah, I guess I’d rather be in here, than wrapped in your ear,’ Finn sang along. ‘This is an awesome home. I’m glad I’m not alone.’

The louder they sang, the stronger they became.

One by one, the glowy worms filed out of the treehouse, with the Worm King right behind them. When the last of them left, Jake slammed the door behind them, nearly catching one by its end, which made him consider something he’d never before considered.

‘Finn,’ he asked,’ do worms have tails?’

‘They are tails, I think,’ Finn answered.

With that, Finn climbed the ladder to his room and snuggled into his furry sleeping bag. Downstairs, Jake climbed into the open drawer of the cabinet.

The treehouse was warm and quiet, and for a while both Finn and Jake slept soundly. But soon they each began to twitch and turn in their sleep.

Their dreams were haunted by a mysterious figure with grey skin, long black hair and a mischievous grin.

It was Marceline the vampire queen!

The bloodsucking house stealer may have let Jake and Finn back into the treehouse, but she was not done with them. It was just a matter of time before she would once again challenge her worthy opponents to a rematch.
