The level begins next to a Huckit Crab. Two ? Blocks and another Huckit Crab follow. Three lifts float above water, where a Big Urchin and some Urchins are found. A Huckit Crab is found on the second lift, and a ? Block containing either a Super Mushroom or a Penguin Suit is above the third lift. A Huckit Crab is found under a platform consisting of a ? Block and two Brick Blocks with a Koopa Troopa on top. A Super Star is found in the second Brick Block. The player then arrives at another lift, where Urchins and a Huckit Crab are found. A P Switch is also found, followed by an area with multiple Urchins and Huckit Crabs, one of which is above a Brick Block containing a Mini Mushroom. A Big Urchin is found before the Checkpoint Flag.
After the Checkpoint Flag, a ? Block and a group of Huckit Crabs are found on rocky platforms. More Huckit Crabs are found after some water, followed by an area with a log platform and multiple platforms made of Donut Blocks. Big Urchins and Urchins are in the water, while Koopa Troopas are on the Donut Blocks. A Red Ring is also located above Donut Blocks. A Warp Pipe is found at the end of the area, which leads to an area with coins that can be reached using Mini Mario and the Goal Pole.
