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.
