This is the only pyramid level in the game and features Pokeys and Blokkabloks as main enemies. Mario starts in a ground full of spikes, as well as four coins and one Pokey, who sprouts from the sand. The second room contains more spikes, a Pokey and a Blokkablok. Entering by an elevator, Mario reaches a room which the floor is made entirely of raising and lowering platforms with Pokeys on them. By finding the right platform, the player can enter a corridor, where the Checkpoint Flag is located. This area also contains spikes, a Blokkablok and two elevators. The next room contains two Blokkablocks and a pit with spiked platforms being the only way to cross it. A Red Ring is found in this area. To the very right of this room, there is a Warp Pipe that leads to the exterior of the pyramid. This last area has a Flying ? Block and raising platforms, that can be useful to reach the Goal Pole.
