Once this room floods, he must swim to a small corridor in the top right of the room. In World 2-3, when Mario hits the ? Switch to raise the water level, he must swim upwards and hit another ? Switch in the room above. This unlocks the Warp Cannon, which in turn leads to World 5.

After destroying a second set of bricks via shell-dashing, Mario must enter the red Warp Pipe, which leads him directly to the red-flag exit. The player has to enter the gap and keep moving to an enclosure of bricks near a yellow Warp Pipe that must be shell-dashed into. In the room with the second Star Coin and shifting blocks, the player can find a gap that never closes on the right side of the room. In World 1- Tower, Shell Mario is required in order to reach the secret exit. This leads to a Toad House and a shortcut to World 1. Exiting through this pipe brings Mario to the red-flag exit. This leads to a small area with a Warp Pipe and the third Star Coin. In World 1-2, on the second tilting platform, Mario must jump onto the terrain above the bricks and coins.
