Wario Land 3: Part 17: Tower of Revival (Gray Chest)

Description:

Red and Blue Skull Rings from the Red Chests of The Volcano's Base and The Pool of Rain cause the Tower of Revival to rise. To begin the climb, you must light torches, which involves using Hot Wario to burn his biscuits. Puffy Wario appears as both a helper and a hindrance, while Fat Wario must shift his weight to create an opening for Puffy to float through. After obtaining the Gray Key at the top, you return to the bottom where the Gray Chest is located. The chest contains Swimming Flippers, allowing Wario to dive and swim underwater, and the game grants him gills.
