The level begins in an area with a Warp Pipe and the right side blocked by Hard Blocks. After taking the Warp Pipe, the player is taken to an autoscroller cave. The player traverses on ground and bridges with short pits throughout the cave and a Mushroom Platform at the beginning. The Koopa Troopas and Galoomba can be seen near the beginning of the cave. Three Fire Bars, the ten coins, Rotating Blocks, ? Blocks containing Super Mushrooms, a 1-Up Mushroom, and the Grinders can all be found on tracks. At the end, several objects rotate around a bride near the Warp Pipe. Back in the main area, there is the last Fire Bar on a rectangular track and the Giant Gate.
