Mario begins the level on a platform, with a Lava Bubble and a Fire Snake nearby. Two ? Blocks can then be found, and a power-up can be found in the first one. After the ? Blocks, more Lava Bubbles and Fire Snakes are encountered, along with some rocky Semi-Solid Platforms with coins on top. After some long Semi-Solid Platforms that are above the lava, Mario arrives at the Checkpoint Flag. A Fire Bar and two ? Blocks can be found above a platform. Mario then encounters Lava Bubbles that jump diagonally over platforms, along with fireballs that are fired from Gray Bowser Statues. After a few more platforms, a Red Ring is found. Going through the ring causes a Coin Coffer to appear, dropping Red Coins as it bounces. Mario then must cross some more platforms, where he encounters Donut Blocks and Fire Bars. Mario then encounters four Gray Bowser Statues on a wall, along with a platform with a Fire Snake on it. Mario then arrives at the Goal Pole.
