World 1-6 (New Super Mario Bros. Wii)

World 1-6 is the seventh and sixth regular level of World 1, and the seventh level in New Super Mario Bros. Wii. It is another grassland world composed of rolling green hills, moving faster than those encountered previously. On the world map, the player has the option of playing either this level or World 1-5; both bring the player to the World 1 Castle.

Layout
The level itself starts with three rolling hills, with Koopa Troopas and Paratroopas on them. Following there is a larger platform. The center Brick Block on this platform contains a Beanstalk, which takes the player to a bonus area containing a Roulette Block. The next section has a pair of floating platforms guarded by Paratroopas, and a Piranha Plant in a pipe in the area below. This is followed by another rolling hill with a pair of pipes containing Piranha Plants and a larger platform with the Midway Flag. There is a hidden Warp Pipe located below the Midway Point and to its left on the game screen. To access the pipe, the player must drop onto the next rolling hill and back-track with a jump into the hidden area. The Warp Pipe sends the player to a sub-terrainean screen with a very fast rolling rock hill. Beside the entrance Warp Pipe are two more that spawn Goombas onto the platform. The exit Warp Pipe is located to the left side of the entrance one.

Back at the surface, the next rolling hill also has a Goomba-spawning pipe above it. Beyond the pipe is a Brick Block that yields a P-Switch when hit. The P-Switch exposes small blue coins. At the lower end of this same Rolling Hill there is another Brick Block. This block has a 1-Up Mushroom inside. After the next platform with a Koopa Troopa, Mario must jump on three larger rolling hills before it reach the Flagpole.

Star Coins

 * Star Coin 1: Floating above the third rolling hill. It can be obtained by jumping on a Paratroopa's head or using the Propeller Suit
 * Star Coin 2: Before the Midway Flag, there is a platform in midair with the Star Coin on top of it. It can be reached using the floating platform before it or using the sky bonus area then exiting from it and simply jump dodging some Paratroopas.
 * Star Coin 3: Under the Midway Flag, there is a secret area with a Warp Pipe leading to another bonus area. The Star Coin can be found floating beside the trio of Warp Pipes.
