Wario Land 3: Part 22: The Volcano's Base (Green Chest)

The Volcano's Base is the second of the three levels affected by Wario's Flute playing. Find the snake jar at the upper portion of this level where the carts are, and use the snake's head as a climb to reach another game of Golf. The surface here is flat, but the hole is surrounded by lava pits. Even before that, the Green Key is located inside the doorway next to the snake; you will have to swim underwater to reach it. Then the Golf minigame will unlock a path towards the Green Chest. The Volcano Base's Green Chest Treasure is a Crown—shiny!
