At first, Mario starts on a platform above the level with 2 goombas, several blocks, and a pipe leading to the level. When Mario enters the pipe, it takes him underwater with many cheep-cheeps. At first, Mario encounters many sets of sub-species of Cheep-Cheeps. A few platforms above water before the checkpoint, a red ring can be found before a set of Cheep-Cheeps. After the checkpoint, the player will encounter a cheep-cheep, a current, and a star coin. In the next area, there is a group of Cheep-Cheeps, 2 currents, and the next star coin. Then, the player will pass by a clampy and see the next star coin guarded by an urchin and a current. At the end of the underwater area, Mario will pass by a Spiny Cheep-Cheep that will follow Mario. Then, there is a pipe that leads to the end of the level with the flagpole.
- Star Coin 1: After the checkpoint, there is a Cheep-Cheep and a current guarding the star coin. Jump over the cheep-cheep or freeze it to obtain the coin.
- Star Coin 2: When Mario sees the first group of Cheep-Cheeps after the checkpoint, Mario must freeze one of them and ride on the ice block to get pass the currents onto the star coin.
- Star Coin 3: After seeing the first clampy, the coin is guarded by an urchin and a current. Mario must time it right and freeze the urchin to block the current so Mario can get the coin.
