Wario Land 3: Part 62: The Colossal Hole (Blue Chest)

Using the Explosive Plunger Box from Beneath the Waves' Gray Chest, you can blow up the Bomb Blocks in The Colossal Hole. A new doorway opens to the northeast of the starting area, which requires an Owl to access. In the next room, you must navigate through many snake pots; use their heads to reach the Blue Key and then the Blue Chest. Watch your footing and avoid burning yourself, or you'll waste time. The Blue Chest treasure in The Colossal Hole is a locomotive—just a little train to keep!
