Layout
This is the first castle level in the game, filled with lava and features many gear-shaped platforms. The Player has to hide in the holes in the gears to avoid being crushed. Thwomps and Super Thwomps make their only main appearance in this castle. If the player rides one of the gears upward he may find a little area with coins, a Propeller Mushroom and two 1-Up Mushrooms. Larry Koopa is fought again at the end of the level. In this fight, Kamek makes five moving platforms move. The first, third, and fifth go the opposite way of the second and fourth. Like all other battles, it takes three hits to win the battle.
