Everything is backwards! Finn is suffering from Quest Deficiency and needs his pals to help him turn up a righteous quest that will fulfill all his adventuring needs!

It's a race against time as Finn and his merry band of questing cohorts fight to complete this switch-a-roo of a mission before the land of Ooo completely destroys itself!
