This level is divided into two segments. In the first, the chosen character has to walk through the desert as they avoid traps like quicksand and new enemies, such as Pokey cacti, Cobrat snakes, and numerous Pansers. In the pyramid, the character has to dig through sand until reaching the bottom. Pink Birdo is fought in a chamber full of chasms.
