Key Cavern is the third dungeon, located in the Goponga Swamp. You'll need the Pegasus Boots to access it. This dungeon is characterized by its numerous locked doors, requiring you to find many Small Keys. The main item you'll acquire here is the Hookshot, which allows you to grapple across gaps and pull distant objects. The Hookshot is invaluable for both dungeon progression and overworld exploration. The boss of Key Cavern requires precise timing and use of your new item.
