Key Cavern

The third dungeon in Link's Awakening. Link will need Slime Key to enter the dungeon, which is found under the Owl statue in Richard's Villa. He must first return the Five Golden Leaves that Richard left in Kanalet Castle before Richard gives Link access to the key. The dungeon is based on finding numerous keys to unlock your way to the end, as you can ascertain. The main item in the dungeon are the Pegasus Boots. And after defeating the boss, Slime Eyes, Link will be awarded the Sea Lily's Bell.
