Overview
Mario starts this level on a grassy area with flowers, a wooden pipe board and a Coin Coffer. Near of this place, there is a large pool of water. The goal is right ahead and can be quickly accessed by a Wall Jump on the wall, or the player may use a Tanooki Suit to cross the gap. Although, Mario must jump on the pool, to collect Star Medals. Mario must swim down, until reach in an area with some crates, two Cheep-Cheeps and a P-Switch. Pressing it, the wall on the right will reveal a passage. After crossing some Spiky Plants, the plumber faces two Porcu-Puffers guarding another passage. This passage splits into two. Swimming through the first opening, Mario can break many Brick Blocks to get a + Clock. In the second opening, Mario is taken by a stream to the Checkpoint Flag. Then, he must swim inside a U-shaped hollow, where are four Spike Eels and a single Porcu-Puffer. Mario will reach inside a dry area with a Warp Pipe, a Piranha Plant and Crates. The pipe leads Mario to the ending area, with more Warp Pipes, another Piranha Plant and the Flagpole.
