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 of a platform onto a sand geyser towards the player. There is then a series of 4 sand geysers, the last of which is right below the first Star Coin. After this is another sand geyser, and a Brick Block which contains a 1-Up Mushroom. Next is a section with geysers and many Goombas, which are continually being produced by a red Warp Pipe. There are more geysers, a Boomerang Bro, and the halfway 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 of which is elevated occasionally by a sand geyser. After some more geysers, there is the third Star Coin, which is obtainable by jumping on a red Koopa Paratroopa, and throwing the shell to obtain it. After this, there are more geysers, Koopa Paratroopas, a Boomerang Bro, and the goal.
