New Super Mario Bros. Wii/World 1-4

World 1-4 is the fifth level and the first underwater level in New Super Mario Bros. Wii.

Normal Strategy
In the starting area, hit the first ? Block to get a Super Mushroom or Ice Flower. Proceed down the Warp Pipe to the water area. Use the Ice Flower to freeze Cheep Cheeps swimming toward you as you go to the right. The first ? Block has an Ice Flower if you need it. After the red Warp Pipe section, freeze a Cheep Cheep and jump on it after it floats to the surface. Then, jump onto the platform, and take this upper path to avoid the enemies in the water. This will also activate a Red Coin Ring. Grab the eight red coins, then continue on. Freeze the Cheep Cheep near the air spewing red pipe, then jump on it and to the left to collect the first Star Coin. Swim past the Pufferfish, freezing them as necessary, though be warned that they will unfreeze and sink after a few seconds. In the next section, freeze a Cheep Cheep when it is directly under the Star Coin, then "ride" it as it floats up to the Star Coin. Continue onward, dodging the pufferfish and avoiding getting crushed by the clam. Freeze another pufferfish that is hovering over a Warp Pipe. Then, swim past it, collect the third Star Coin, and enter the Warp Pipe to the first bonus room. Keep swimming, watching out for Cheep Cheeps, especially the kind that chases you. Exit through the Warp Pipe, using the Paratroopa to reach the top of the flagpole, and finish the level.

Bonus Rooms
The first and only bonus room is reachable by entering the Warp Pipe right next to the third Star Coin. In it are several 1-Up Mushrooms being guarded by Clams, coins, blocks, one of which contains an Ice Flower, and a Cheep Cheep that follows you. Exiting takes you to a Warp Pipe farther along the main path.

Star Coins

 * Star Coin #1: When you see the first star coin, freeze the Cheep Cheep, then jump onto him and to the star coin.


 * Star Coin #2: A short way after the first star coin, you see one wedged between two red pipes. Freeze one of the large Cheep Cheeps below then float underneath him up to the coin. Once you've got it let the currents thrust you back down.


 * Star Coin #3: At the sight of the third star coin, freeze the Urchin right as he is floating above the red pipe. It will then sink down and block the bubbles, allowing you to swim to the star coin.
