The Key Cavern is the third Dungeon in Link's Awakening. The Dungeon's entrance is behind a fence of statues resembling Slime Eye, one of which has the Slime Keyhole. Despite being called a cavern, this Dungeon isn't set inside a cave, but more or less a bricked building. The Slime Key, which is possessed by Prince Richard, is required to enter. The mini-boss of this Dungeon is a pair of Dodongo Snakes, which require Bombs to defeat them. The main tool of this Dungeon is the Pegasus Boots, which is necessary to break away blocks that cannot be bombed as well as used to aid Link in defeating the Boss, Slime Eye, who guards the Sea Lily's Bell.
