World 6-Tower (New Super Mario Bros. 2)

 is the tower of World 6 in New Super Mario Bros. 2. It primarily features dodging Rocket Engines, some of which are blocks that can be temporarily deactivated by hitting them. It is the last Tower in the game, as World Star does not feature one.

Star Coins

 * Star Coin 1: The first Star Coin is in plain sight, but Mario or Luigi can't reach it unless they temporarily turn off the Rocket Engine that is blocking it.
 * Star Coin 2: The player must enter the door left of the Checkpoint Flag (and turn off the Rocket Engine). The door leads to a large room infested with Rocket Engines. The second Star Coin is at the very top of the room.
 * Star Coin 3: Just before Mario or Luigi fight the Reznor, there is a green pipe that is blocked by a Rocket Engine. After deactivating it, the green pipe will lead the player to a room with circling Rocket Engines. The player must climb the Rocket Engines to find the third Star Coin.

Enemies
