World 2-A (NSMB)

World 2-A is the first and only bonus level of the second world in New Super Mario Bros..

Level Description
Although this world is in the middle of a desert, this level is largely inhabited by water. The level is fairly monotonous, as opposed to most other levels in New Super Mario Bros.. This level features three types of enemies: Koopa Troopas, Koopa Paratroopas, and Spike Basses. The player must traverse across many platforms and utilize several Spin Blocks to proceed through the level. By using the Spin Blocks, the player can gain access to multiple hoards of coins hover in the sky. By using the final Spin Block, the player can access a secret exit. He or she must bounce on the final Koopa Troopa while still spinning in order to gain access to a gold pipe; this pipe leads to the secret exit. The player can also access the normal exit via the utilization of the green pipe – this pipe is located directly below the gold one. Once the player touches the flagpole, the level ends.
