World 3-2 is the twelfth level of Super Mario 3D Land. It is the first water-themed level of the game.
The level begins with Mario swimming into a small pool surrounded by rocks. Inside of the pool is a Warp Pipe that takes Mario to the actual level. Inside, the level plays out like a regular water-based lavel from Super Mario Bros., but contains some parts that are above ground. After a small stream with cheep cheeps, Mario finds the Checkpoint of the level, and past that, finds some Porcupuffer. There is also a Fire Flower Mario can use to defeat the enemies, even though he is underwater. Past the Porcu-Puffers are the debut of the Spike Eel. One of these blocks the way to the Warp Pipe that leads to the Flagpole.
After reaching the Warp Pipe, Mario can take a different path, also blocked by a Spike Eel, that leads to the final Star Coin of the level, and a special Warp Pipe that leads him to the top of the Flag Pole.
Star Coin 1 - The first Star Coin is behind a cage. To go inside the cage, there is a hole in the wall which leads to the Star Coin.
Star Coin 2 - While avoiding the Spike Eel, go down the small rectangular manhole. There is nothing down there but a pipe. Inside the pipe is a small room, holding the Second Star Coin.
Star Coin 3 - To collect the third Star Coin, the procedure is similar to collecting Star Coin 2, but instead Mario/Luigi has to swim upward, avoiding yet another Spike Eel. The Third Star Coin is above the water.
