World 2 is the second world of the game New Super Mario Bros. Wii. It is desert-themed, and consists of eight levels, of which two are castle levels guarded by Roy Koopa. This level is throttled with Mushroom Houses, assisting the player by forking over items such as Starman, Mushrooms and Propeller Mushrooms.===

At one point in the world, there is an area in which Mario and his cohorts can get sucked into the sand and play in a level where they have to collect all the Toad Balloons without losing.
