The level begins with a ? Block containing a power-up, along with a Stone-Eye moving in a pit of quicksand. To the left of the starting area is another Stone-Eye. Above it is a Hidden Block containing a Super Acorn. Some Waddlewings are found, along with palm trees that act as platforms. Another Stone-Eye is found, along with a ? Switch. A section with multiple Stone-Eyes with Koopa Troopas on them follows, with Paratroopas flying above. Another Stone-Eye is found, along with some Piranha Plants and Goombas. A Koopa Troopa is on a palm tree. More Waddlewings are found, one of which is holding a Super Acorn, and are followed by the Checkpoint Flag. Moving Stone-Eyes and Sand Geysers act as platforms to cross pits. Paratroopas are found in between the platforms. Following a series of large Stone-Eyes that begin to lower, the Goal Pole is found.
- Star Coin 1: The first Star Coin sits in plain sight, and the player must leap off the Stone-Eye below to obtain it.
- Star Coin 2: The player must use the Flying Squirrel suit or Peachette (New Super Mario Bros. U Deluxe only) to reach a Warp Pipe on the tree after the Checkpoint Flag; it leads to the second Star Coin. In multiplayer mode, one player can also jump on another player's head to reach the Warp Pipe.
- Star Coin 3: Within a Sand Geyser, the third Star Coin can be collected by waiting until the geyser comes up, or when the Stone-Eye moves so the player can grab it while the geyser is up.
