Finn and Jake face their toughest trial yet in a brand-new chapter—written and drawn by cartoonist/writer Nick Winn (Silver Sprocket's Bloody Mary)! The world may be ending, but that won't stop the star-crossed (and newly reunited) Simon and Betty from a special night out—even if the past is threatening to catch up to the present . . .  Meanwhile, Computer Princess has sent out the global SOS, and it's all hands on deck for the ultimate test: saving Ooo from the terror Magic Man unleashed at the blood banks. From the biggest Gumball Guardian to our not-so-tiny Ravine, will our heroes be able to keep the world from becoming splitsville?
