Wario Land 3: Part 58: Cave of Flames (Red Chest)

Description:

After starting the level, go left and bounce off the enemy with your High Jump Boots. In the next room, the Red Key is hidden between the rock pillars; fall down the correct two to reach it. Then cross a gap into the next room and climb. Get a Doughnuteer to transform into Fat Wario, then use the extra weight to bash through the Doughnut Blocks blocking the Red Chest. The Red Chest contains a Minicar, a small trinket to keep.
