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

World 1-6 is the sixth level of New Super Mario Bros. Wii ' s World 1, and the sixth level of the game overall. It is another grassland world composed of rolling green hills, moving faster than those encountered previously.

Layout
The level itself starts with three rolling hills, with Koopa Troopas and Paratroopas on them. Following this 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 toward the end. 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 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 is another Brick Block. This block has a 1-Up Mushroom inside. After the next platform, a series of three larger rolling hills come just before the Flagpole.
