This door leads to the red-flag exit, revealing the path to a Warp Cannon, which in turn leads to World 6. In World 3-, after hitting the ? Switch that reveals a Warp Door, Mario must pass that door and travel down the large staircase to enter another door. After going down that pipe, he must jump across several Mushroom Platforms to reach the red-flag exit leading to World 3-B. Mario must jump into the green pipe, then go down the next green pipe immediately after. In World 3-2, on the first moving mushroom after the midway point, there is one green, one yellow, and one red Warp Pipe overhead. The pipe brings him directly to the red-flag exit, which in turn leads to a Toad House and a shortcut to World 2-6. After going down the staircase-like formation, Mario must go left and tread through the water to enter a small pipe. In World 2-4, Mini Mario is required for this secret exit. This leads to the Warp Cannon, which in turn leads to World 5. Going into the pipe brings Mario to the third Star Coin, then a red Warp Pipe to the red-flag exit. In World 2-A, after Mario jumps off the final Spin Block, he must time his landing correctly so he bounces off the Koopa Troopa in order to direct himself into the yellow Warp Pipe in the cavern directly above. Entering it brings Mario to the red-flag exit, which leads to World 2-A. 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.
