The player unlocks this level after reaching the secret exit in Tilted Tunnel.

The level's title card

This level begins on a platform made of Warp Pipes, with one that leads the player into the underwater section. The underwater section has many Jet Pipes that forces the player in a certain direction or expel Bloopers. The section begins with two Jet Pipes on the left side. A ? Block containing a power-up is found, followed by two diagonal Warp Pipes containing Bloopers. Yellow Jet Pipes that alternate blowing currents are found, along with three more Bloopers. A ? Block containing a power-up is followed by another Blooper, as well a section with multiple Jet Pipes and rotate ninety degrees. The player continues through a section with more Bloopers and rotating Warp Pipes, including a group of four Warp Pipes that move in a circle. A Red Ring is found, along with more Jet Pipes and a Blooper in a section leading to a Warp Pipe that leads to the next area. Two Bloopers are found at the beginning of the area, which is vertical and contains Jet Pipes that rotate in circles. On the right side next to the red Warp Pipe is a Hidden Block containing a 1-Up Mushroom. A Warp Pipe at the end of the section leads to the area with the Goal Pole.
