World 7-4 (New Super Mario Bros. Wii)

World 7-4 is the fourth level of World 7 in New Super Mario Bros. Wii. This level has some similarities to World 7-1, except instead of moving blocks, there are moving Warp Pipes.

Layout
The level begins near a platform that can be activated by pressing a block in between two ? Blocks. When the player turns the Wii Remote left or right, the platform heads in the direction that the Wii Remote is tilted. Two Koopa Troopas are found, along with a Warp Pipe leading to the next area. It takes the player to an area in the sky with moving Warp Pipes and a ? Block containing a power-up. More moving Warp Pipes are found with pits and rising Bill Blasters in between them. Piranha Plants are found in some of the pipes. A platform with a ? Block above it is found, followed by more Warp Pipes. A group of three Bill Blasters is found, followed by Banzai Bills being launched from a Banzai Bill Cannon. A stationary red Warp Pipe takes the player to the next area. The midway point is found, followed by more platforms activated by grey blocks. More Warp Pipes, some of which move, are also found in the area. After a group of platforms over a pit, another Warp Pipe is found. Through the Pipe, multiple moving Warp Pipes with Koopa Troopas on them are found. A Koopa Paratroopa is found, along with a Red Ring. A platform with a Koopa Troopa, a Piranha Plants, and two ? Blocks on it, followed by more Warp Pipes. Koopa Troopas, Koopa Paratroopas, and Bill Blasters are found. At the end of the area, a Warp Pipe leading to an area with a quickly-moving Warp Pipe and the pole.

Star Coins

 * Star Coin 1: The first Star Coin is floating to the top-left of the Banzai Bill Cannon directly after the Warp Pipe that leads to the next area. Mario and co. must get on the moving Red Pipe to the right of the exit one, avoid any Banzai Bills, and jump to the Star Coin while the Pipe is at its highest point.
 * Star Coin 2: The second Star Coin is right under the top of three command platforms arranged in a column. Mario and co. has to get on the top one, tilt it to the left, and jump to the bottom one, grabbing the Star Coin in the process.
 * Star Coin 3: At the end of the level, instead of taking the red Warp Pipe, Mario and co. must use the Bullet Bills to get into the green Pipe further to the right. Once there, Mario and co. must go left and again use Bullet Bills to reach the third Star Coin on top of the tallest Bill Blaster.
