World 3-Tower (New Super Mario Bros. Wii)

 is the tower level of World 3 in New Super Mario Bros. Wii.

Layout
This level features brightly colored rotating blocks that must be used to climb to higher locations. Rolling Spike Balls, Dry Bones, and Amps are some of the hazards that must be avoided as the floor scrolls upward. The last half of this level resembles Castle Crush, a level found in Donkey Kong Country 2: Diddy's Kong Quest. At the end of the tower, Lemmy Koopa is found balancing on a yellow ball in an icy arena. The player(s) must attempt to defeat him while avoiding the yellow balls that Lemmy conjures otherwise they have the risk of being pushed off the level. Lemmy will also spin in his shell trying to hit the player(s) when hit. Like most other bosses, Lemmy must be hit three times to be defeated.

Star Coins

 * Star Coin 1: To the top-right of the second rotating block, there is a hidden area with a Warp Door. After getting there by jumping from the top of the block, Mario and co. will be led to an area with another rotating block, a Spinner, a circle of Coins, and the first Star Coin. Mario and co. must jump into the block and jump up to the Star Coin while avoiding the Spinner.
 * Star Coin 2: Right near the second POW Block, the second Star Coin is to the left and blocked off by many blocks. Mario and co. must let the Spike Balls destroy the blocks, use the aforementioned POW Block to get the Spike Balls out of the way, then get the Star Coin.
 * Star Coin 3 (pictured): The third Star Coin is floating just below Lemmy's door. To get it, Mario and co. should get on the final rotating block, jump from it to the right path, then get the Star Coin while avoiding the Dry Bones.
