Wario Land 3: Part 48: The West Crater (Red Chest)

Now that Wario can use the Super Ground Pound, he can use it against the solid purple blocks blocking a warp pipe in this level. First, break through the left wall and return to the room where you encountered Silky, who turns Wario into Ball O'String Wario. Pick up Silky and use it to break the enemy blocks upward in that same room, which eventually leads to the red key. Return to the first spot, unseal the warp pipe, and then the next room will have you on trolleys. Maneuver and ride them back and forward while dodging obstacles and hazards, and you’ll eventually reach the red chest. The West Crater's red chest treasure is a saber—just a collectible; Wario can’t and won’t use it for anything else.
