Stand on each of them and jump to reveal three hidden blocks. After climbing several sets of stairs (all guarded by block-busting ghosts), you'll finally see three regular blocks floating on the far left of the screen.

This will also lead to a red pipe leading before the yellow pipe that Mario or Luigi entered.This is one of the trickiest we saw. Mario should move left while avoiding the Super Piranha Plant. If Mario tries to go up, he will trigger Invisible Blocks with that contain coins or a power-up, which means he will be forced to enter (similar to World 8-4 of Super Mario Bros.: The Lost Levels in the final room).

Star Coin 3 - Before the end pipe, Mario should head down a yellow pipe after the green pipe.

It is easier with Small Mario, as the gap on the wall is two blocks tall. Instead of falling down, Mario should Wall Jump. He should fall in an underground area that has Spinies in it.

Star Coin 2 - Mario should enter a pit of quicksand that is higher than the rest.

Star Coin 1 - Mario should ride the first tornado and head right to get the Star Coin.After exiting a pipe, Mario will reach the pole. When he exits out of a red pipe, he should enter the green one next to it. Mario should enter the single yellow one to go to an area with the third Star Coin. After the midway point, Mario should find an area with several pipes. If Mario goes into it, it will take him to an area containing the second Star Coin.

The player should see a part of the quicksand that is higher then the rest. Later, Mario should be met with two Lakitus at once.

The first tornado allows Mario to obtain the first Star Coin. There are also Lakitus chasing Mario throughout this level. This level takes place in a desert, and it is the only level in the game that has tornadoes.
