Wario Land 3: Part 19: The Pool of Rain (Green Chest)

After dodging the water so much in The Pool of Rain, you can now interact with it better thanks to the Swimming Flippers. Try to find an underwater doorway in the water. In this next room, Wario will be pushed around by a lot of water currents; memorize their paths to find the Green Key in the bottom‑right corner of the room, as well as the doorway above it. This leads into another boss fight against a kitsune called Wolfenboss. He will either shoot bouncing fireballs at Wario, forcing him up and out of the fight, or launch spiked balls that threaten to turn him into Puffy Wario, which also floats him out. You must wait until the spiked ball opens to release a small enemy called a Kuri, then carefully line them up to knock them right into Wolfenboss. Repeat this three times to win, and then you can finally reach the Green Chest. The Pool of Rain's Green Chest is an ornamental fan; Wario fans this mystical fan, blowing away the mist that blocks the East Side of the Music Box world, allowing access to its first level, The Stagnant Swamp.
