This is the second underwater course in the game overall. After the player enters through the pipe, they will come across some coral next to a couple of coins. Two Boobers are encountered here. Three coins are placed above here. A taller branch of coral lies ahead, followed by three more coins. A small piece of coral sits a small floating platform here in this section, where another Bloober is found. Following after another piece of coral are two more Bloobers.
Up ahead is a current, with three coins placed there. Ahead, the player will encounter two Bloobers and three gray Cheep Cheeps. Ahead are two gray Cheep Cheeps and one red Cheep Cheep, along with three more Bloobers. Three more coins are found underneath a small platform with coral on it. Three more coins are found ahead, where a single gray Cheep Cheep is encountered. A single red Cheep Cheep is found shortly before the next current, which has a larger pit than the first, and contains four coins lined up like a smiley face. Two gray Cheep Cheeps swim past here. Two more Cheep Cheeps approach, along with a Bloober.
Right here, the player will approach another current, with six coins in the center. In the final section that follows are five more Cheep Cheeps and two more Bloobers. The exit pipe is placed at the very end. Upon taking it, the player will be lead back to the overworld, emerging from a pipe containing a Piranha Plant. Just over the staircase is the flagpole.
