World 5-C is the third bonus level of World 5 in New Super Mario Bros.. It is unlocked after completing World 5-B and completing this level will unlock World 5-4.
==Layout==
The level starts in a snowy area with a green Warp Pipe to enter. Entering the pipe leads Mario underground. After passing a Buzzy Beetle, a Question Block and two Broozers, the first Star Coin can be seen inside blocks that can only be destroyed by a Broozer. After more sets of blocks, including a block that contains a Starman, you will traverse vertically-moving platforms before seeing the second Star Coin over an abyss. It's impossible to obtain without dying, so a Buzzy Beetle must be thrown at it. Just after the checkpoint is a set of four blocks, with one containing a Vine to a snowy area above the main level where the third Star Coin can be obtained after hitting a P Switch and leading the Broozer to break blocks blocking it. A narrow opening in this section also leads directly to the flagpole. If you continue moving forward, you are required to hit an orange ? Switch to make red blocks appear which lead to a pipe that takes you to the end of the level. In this section, you also must be aware of Broozers breaking the red blocks behind you as they soon fall from platforms above.
==Star Coins==
*Star Coin 1: Located inside a column of Brick Blocks. Mario must not kill the Broozer here, as he has to lead the Broozer to break the blocks so that the Star Coin can be obtained.
*Star Coin 2: Just before the checkpoint, located over an abyss. It cannot be obtained directly, so Mario must use a Buzzy Beetle to throw it towards the coin.
*Star Coin 3: Just after the checkpoint, located in a secret area. In a row of four blocks, Mario must hit the one farthest to the right, to reveal a vine. The block above must be destroyed first so the secret area can be accessed. Mario must then hit a P Switch to turn blocks into coins and let the Broozer destroy blocks that block access to the Star Coin.
