World 2-1 (New Super Mario Bros. Wii)

World 2-1 is the first level of the second world in New Super Mario Bros. Wii. This level takes place in the desert and is the first level with sand geysers. This level has only one room, and no secret rooms that are reachable. All of the Star Coins are in plain sight, and rely on using the sand geysers to get them. This level may be entirely skipped in favor of World 2-2.

Layout
The level starts with a Koopa Troopa walking off a platform onto a sand geyser toward the player. There is then a series of four sand geysers; the last is below the first Star Coin. After this is another sand geyser and a Brick Block containing a 1-Up Mushroom. Next is a section with geysers and a red Warp Pipe continuously spawning Goombas. There are more geysers, a Boomerang Bro, and the Midway Flag.

There are more geysers, this time with Koopa Paratroopas, and there also Piranha Plants on several of the main platforms. The second Star Coin is in a small indentation in one of the platforms. There is then a section with many Piranha Plants; one is elevated occasionally by a sand geyser and need to be dodged. After some more geysers, there is the third Star Coin obtainable by jumping on a red Koopa Paratroopa, and throwing the shell to obtain it or using a Propeller Mushroom. After this, there are more geysers, Koopa Paratroopas, a Boomerang Bro, and the Goal Pole.
