World 9-2 (New Super Mario Bros. Wii)

World 9-2 is the second level of World 9 in New Super Mario Bros. Wii. It takes place in a beach setting. The player must get to the goal by avoiding a Porcupuffer and many Koopa Troopas and Koopa Paratroopas.

Layout
Mario begins the level near two Koopa Paratroopas and a Piranha Plant in a Warp Pipe, along a Porcupuffer that can be found in the water below. Mario can then find a Koopa Troopa, along with a group of ? Blocks and Brick Blocks. Three Switchback Platform that descend when Mario touches them are then found, along with a beach area where Koopa Troopas can be found. Mario can use one of their shells to break Brick Blocks, allowing him to obtain a 1-Up Mushroom from a block. Another Switchback Platform can then be found, along with a Warp Pipe that takes Mario to an underwater area, where a Cheep Chomp can be found guarding the second Star Coin. After the Switchback Platform, a few vines that help Mario cross the water can be found, along with more Koopa Paratroopas.

After the vines, Mario arrives on a platform, where a group of four blocks can be found, one of which containing a P Switch that causes Blue Coins to appear when pressed. Following the Blue Coins leads to a Hidden Block with a 1-Up Mushroom inside of it. After the group of blocks, Mario can find a group of Koopa Troopas, along with Stretch Blocks. Hidden Coins can be found above some of the Stretch Blocks. After the Stretch Blocks, a group of Koopa Paratroopas can be found, along with the Goal Pole.

Star Coins

 * Star Coin 1: The first Star Coin is floating under a descending platform not too far from the beginning of the level. Mario and co. must get on the platform and descend to the Star Coin, while simultaneously avoiding the Porcupuffer.
 * Star Coin 2: Soon after the first Star Coin is a long descending platform to the left of a Green Pipe. Mario and co. must get on the descending platform and enter the Pipe once it gets low enough. This leads to an underwater area with the second Star Coin, several other Coins, five wind-blowing Pipes, and a Cheep Chomp. Mario and co. must swim to the Star Coin while simultaneously avoiding the Cheep Chomp.
 * Star Coin 3: Near the end of the level, the third Star Coin is under a platform that is blocked off by Brick Blocks. While also avoiding the Porcupuffer, Mario and co. must use the nearby Koopa Troopas to break the Brick Blocks and make the Star Coin accessible.
