Wario Land 3: Part 27: The Tidal Coast (Gray Chest)

Description:

A new aquatic level for this game, but no time to play in the water too much, yet. Wario first has to get himself burned again, as the Gray Chest is blocked by Fire Blocks. The Gray Key is above it, which can be reached by bonking Wario into bounciness. The Tidal Coast's Gray Chest Treasure is a Yellow Book, but nothing can be used with this yet. Maybe the Bank of the Wild River will have the other piece of this puzzle.
