In the Land of Ooo, a somewhat dystopian fantasy land full of dragons, knights, talking animals, monsters, talking inanimate objects and humanoid candy creatures, a boy named Finn (who is the only human in Ooo), and his best friend Jake (a magic dog who could stretch into different shapes and sizes) go on crazy adventures. They must find a legendary book called the Enchirideon. It's a handbook for heroes and it has cosmic powers.
