History
When Finn encountered the Bucket Knight in the Crystal Eye Dungeon the diminutive creature demanded that the boy fight him to earn his passage. Finn, thinking that he could just run past his tiny opponent, got the fright of his life when the Bucket Knight transformed into its giant form and attacked him. After taking a heavy beating, Finn was luckily able to escape through a door too large for the enormous Knight to follow him.
