A/N: Hey y'll. I'm rewriting this story :P.
"Haiyaaaaaaah!" a boy with a bear-hat yelled as he lunged with his sword in his hand at an old-looking wizard who is wearing a crown. Unfortunately, before the sword made contact, the wizard shoot a blue beam from his hand. The boy's hand was hit by the beam, and his hand is now frozen.
"Glob damn it! Jake!" The boy shouted as he tried to free his frozen hand.
"Got it, dude!" A yellow dog said as he came running with his hind legs. His hand became a spiked ball and he tried to punch the wizard, but the wizard dodged.
"Haha!" The wizard mocked. He prepared to shoot another ice beam, but the boy before ran up to him and smacked him in the back with his frozen hand. The wizard turned around, but he received another smack from the boy. The wizard fell to the ground, unconscious.
"And the job's done, Jake." The boy said.
"Yup. I bet Ice King will do this again tomorrow, Finn." The dog, named Jake, said.
The boy, named Finn, chuckled. "Yep." He said. "Let's go free PB and get out of here."
Jake walked up to a cage and opened it. Then, a pink woman (made out of bubblegum, I think?) walked out.
"Thank you for saving me again, Finn and Jake." The woman said.
"No problem, Princess Bubblegum!" Finn said.
"Come on, let's get out of here. I have a date with Rainicorn." Jake said.
"Fine." Finn said. "To the kingdom!"
The screen changed. We see the Earth - or what was left of it after The Great Mushroom War. Then, we see a weird-looking spaceship hovering above it.
We zoom in inside the ship, and we see a shadowed figure talking to his robot minions.
"We're here. Contact our customer."
