Star Coin 3: For the third Star Coin, Raccoon Mario is required.

Star Coin 2: When Mario reaches the pipe, he should ignore it and continue forward where the second Star Coin is.

Super Mario can ground pound the blocks to obtain the Star Coin.

Star Coin 1: This Star Coin is located under two breakable Brick Blocks after the second large Thwomp.

The player can use the walls to reach the key. After three hits Larry will be defeated, revealing the key to World 3. He jumps and shoots magic balls that bounce diagonally. In his room, there are four holes in the room (two in the ceiling and the floor), where walls move up or down. Another Dry Bones will appear, followed by normal ground, where the boss door is located. Moving downwards, there are several rotating Brick Blocks located above several Bone Piranha Plants, where Mario needs to time his jumps. A row of three ? Blocks can then be found, with a Super Leaf in one of them. In the next area another giant spiked ball will chase Mario once again. The checkpoint is found here with two smaller spiked balls bouncing on walls and the pipe to the next area. A large Whomp then appear next to the pipe leading to a small room. Another Big Dry Bones appear before Mario reaches back to ground where the giant spiked ball falls off. This is followed by a Big Dry Bones and several Big Thwomps.

Another Dry Bones appear, followed by several Thwomps above gaps in the platform. A Dry Bones then appear below ? Blocks, one of them containing a Super Leaf. Mario begins on a platform above spiky floors where a giant spiked ball falls and begins to break the platform that Mario is on and chase after Mario.
