World 2-Tower (New Super Mario Bros.)
This level is a tower level that contains many rotating platforms. At the beginning of the level, the player must jump to the first rotating platform, and then onto the second one. Above the second platform reside three ? Blocks, one of which contains a power-up. The player must then jump to the rotating platform located above the three ? Blocks. To the player's right is a Dry Bones that may walk onto the rotating platform. The player must then jump to the left, where another Dry Bones is located. Above the Dry Bones is a rope that the player must climb across to reach a slightly higher platform. Up even higher, another rotating platform can be found. If the player jumps to the left, they will land on a shallow cliff. From there, the player can repeatedly Wall Jump his or her way up to a door. Behind the door, there is a cluster of gold blocks in the shape of an "n". The player must then Wall Jump within the bricks constantly as it rolls along the wire track. At the top, the player must drop out of the blocks, quickly jump up the platforms, and land on top of the blocks. The player can then jump to a new platform, where the first Star Coin can be found. The player must repeat the aforementioned process in the second block structure in order to access another door. The player will then drop back into the main area through the door.
If the player doesn't take the door's path, they can climb along a rope, where they can find a Red Ring along the way. Past the Red Ring, a Springboard can be found. Using the springboard, the player can access the green Warp Pipe that is directly above it. In the next area, the midway point is activated directly before a ? Block. As the player jumps across several rotating blocks, they will encounter two Dry Bones directly beneath a red pipe. On the other end of the red pipe is a door that leads to Bowser Jr.. The battle with Bowser Jr. is the same as the previous one, although there is quicksand below the platform that Mario and Bowser Jr. fight on.
