This is the only level that features Huckit Crabs. There are also a lot of Urchins and Big Urchin.

Star Coins

 * Star Coin 1: The first Star Coin is near the beginning of the level, floating above a ? Block. Mario and co. should get on the ? Block and jump from it to the Star Coin.
 * Star Coin 2 (pictured): Shortly after the first Star Coin, there will be a row of two Brick Blocks and a ? Block with a Red Koopa Troopa on top. The middle Brick Block contains a Super Star. Mario and co. must obtain the Super Star then hurry along and kill the Big Urchin to make the second Star Coin accessible before the Super Star's effects wear off.
 * Star Coin 3: A Mini Mushroom is required for this one. To the direct right of the stairs-like platform with three Huckit Crabs is a small Green Pipe guarded by another Huckit Crab and an Urchin. Mario and co. must get past these enemies and enter the Pipe. This Pipe leads to an underwater area with two Big Urchins and the third Star Coin, which is surrounded by several other Coins in the shape of a heart.
