After a cutscene showing the player character entering a Warp Pipe, they will be dropped into the underground area. Directly above the Springboard is a Brick Block containing a 1-Up Mushroom that will begin sliding to the right above a pit with falling lifts. In one of the blocks in the next row of Brick Blocks is a power-up. Using a horizontally moving lift to enter a narrow passage, the player then has to pass Piranha Plants. After the next falling lift is a split path with Piranha Plants and a group of Brick Blocks, in one of which is a Super Star which the player needs to be in a Super or Fire form to collect. Past downward moving lifts is a Hammer Bro. that will charge at the player followed by Bill Blasters and a Piranha Plant before the Warp Pipe to the Goal Pole.

If the player can jump onto the ceiling of the level and continue right past the exit pipe, they will reach a Warp Zone leading to World B.
