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

World 2-2 is the second level of World 2 in 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 brick block with a P-Switch in it. The next area has several Brick Blocks floating over a pit of quicksand and a Spike on a midair platform. Going up the next hill, there are two Spinies, and down the opposite side there is a Koopa Troopa and three Goombas. Following this there is a vertically moving platform with nine red Koopa Troopas on ledges that can be used to get a 1-Up Mushroom, 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 Flag has a trio of Goombas. On two midair platforms there 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 there is a Warp Pipe leading to a bonus underground area with a Mini Mushroom and a P-Switch. After another desert platform, there are several horizontally scrolling platforms and a Spike guarding the next section. Underneath this next section there is a mini Warp Pipe leading to another underground bonus section with a P-Switch and a Star Coin. Following this there is a horizontally moving platform, another Spike, and the Flagpole.

Star Coins

 * Star Coin 1: To the immediate left of the Checkpoint Flag is a deep pool of quicksand. Mario and co. should get inside it and sink all the way to the bottom. This will lead to an area with a P Switch followed by a large drop, and a Green Pipe at the bottom. This Pipe leads to another area with two Spikes and a ? Switch. Mario and co. should activate the ? Switch to make moving platforms appear, and use them to jump up to the first Star Coin while avoiding the Spikes.
 * Star Coin 2: Not far from the exit point of the area with the first Star Coin is a row of four Brick Blocks. Mario and co. must hit the one on the left from anywhere but the top to make a Beanstalk appear. This Beanstalk leads to a cloudy area with a long moving platform, and this platform eventually leads to a POW Block, which Mario and co. must use to make the second Star Coin, along with several other Coins, fall onto the platform. This should be done while the platform is under the Star Coin.
 * Star Coin 3: A Mini Mushroom is required for this one. Near the end of the level, under the hill, is a small Green Pipe covered by two Barrels. After throwing the Barrels away and entering the Pipe, Mario and co. will be brought to an underground area with the third Star Coin floating atop a midair platform. It must be jumped to.
