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

World 2-2 is the second level of the second world of New Super Mario Bros. Wii; however, the player has the option to play either World 2-1 or this level to advance. Like with 2-1, it is a desert-themed level, which introduces Spikes and Barrels.

Layout
The level starts with Mario standing next to a pair of barrels. Moving on, there is a hill with several Goombas approaching; on the upper platform floating in the air are three more barrels, and the next section has a Spike. The next section down a hill has a Spike standing on several Brick Blocks. In the Brick Block before the Spike and adjacent to the Question Block on the second platform, there is a P-Switch. The area after has several Brick Blocks floating over a pit of quicksand and a Spike on a midair platform. Going up the hill, there are two Spinies, and down the opposite side is a Koopa Troopa and three Goombas. Following this is a vertically moving platform with several red Koopa Troopas on ledges, and the Midway Flag is after this. However, the adjacent quicksand pit leads to a secret area with a P-Switch that spawns several coins, as well as another secret that leads to a Star Coin.

The section following the Midway Floag has a trio of Goombas. On two midair platforms are barrels, with a Spike nearby. Next, there is a vertically moving platform; on the left side of it are a pair of platforms with a barrel on one of them, and the right side has a row of Brick Blocks and a Spike; the first Brick Block contains a Beanstalk leading to a bonus area. The next area consists of several vertical platforms with a Spike on the opposite end of each. The next section has two vertically scrolling platforms, one with a Spike on it. On the left side of the free platform is a Warp Pipe leading to a bonus underground area with a Mini Mushroom. After another desert platform, there are several horizontally scrolling platforms and a Spike guarding the next section. Underneath this next section is a mini Warp Pipe leading to another underground bonus section with a P-Switch and a Star Coin. Following this is a horizontally moving platform, another Spike, and the Flagpole.

Star Coins

 * Star Coin 1: Before the checkpoint, there is a deep pool of quicksand. Enter it to reach the bottom. There is a P-Switch, which upon activating, sends the player falling to the bottom while collecting Blue Coins. Enter the warp pipe on the right into the room with two Spikes on platforms and a ? Switch. Use the switch to activate timed moving platforms to reach the Star Coin.
 * Star Coin 2: After the checkpoint, there is a moving platforms with a Spike and four brick blocks above it. Use the barrel at the left of the moving platform to activate the first block containing a Beanstalk. Alternatively, the player may use a Propeller Mushroom or, if there is two or more players, bounce on another player and hit the block from below. The Beanstalk takes the player to another platform which moves to the right. Use the POW Block along the way to get the Star Coin.
 * Star Coin 3: To the left of the two platforms with a Spike on one of them, enter the green pipe on the left and obtain a Mini Mushroom. Exit the area and continue to the right until reaching the four moving platforms with a Spike at the top ledge. Break the tiny barrels at the bottom ledge and enter the green mini pipe to get the Star Coin.
