Wario Land 3: Part 36: The Colossal Hole (Gray Chest)

The volcano eruption caused by Wario created a new level in the West Side of the Music Box world called The Colossal Hole. This tall level is still largely unexplored, as Wario cannot access many power‑ups or trigger events yet. Players must navigate up to the Gray Key and then to the Gray Chest, where the treasure is the Left Glass Eye. The right Glass Eye is likely in the other new level created by the eruption.
