Keyper at his post outside Mount Cragdor


Keyper appears in “The Enchiridion!” in which he defends the gate and gives Finn and Jake a riddle which he recites in an extremely fast voice. Finn and Jake pass the riddle which Finn says is “because he thought he would look cute in that keyhole”. Keyper later appears after Finn defeats the Dark Magician, and Finn knocks him out because he’s wearing a devil costume. It is then revealed that the devil costume is his pyjamas.
