World 18-7

World 18-7 is the seventh level of World 18 of Super Mario Challenge from Super Mario Maker for Nintendo 3DS.

Course layout
The level begins in an almost empty room with a Pipe that gives Buzzy Shells and a Mushroom Platform. At the end of the room is a Warp Pipe to the subarea. The subarea, in general, is a slow auto-scrolling one-screen-high level with very little ground with Semisolid Platforms in areas of hazards, but the coins are scattered throughout. The first obstacles the player must dodge are Green Koopa Troopas coming from Pipes and two Cheep Cheeps. There is also a Pipe that gives Buzzy Shells after the last Pipe. The next obstacles are Thwomps of different sizes above some ground and three Cheep Cheeps. A Pipe that gives Buzzy Shells separates the sizes. After another Pipe that gives Buzzy Shells, the player must avoid all the Bloopers and three Cheep Cheeps, though they can get Buzzy Shells from two Pipes and put them on by going onto the nearby ground. Almost immediately afterwards, the player must avoid Angry Wigglers from three of the Bullet Bills, while a fourth middle right one shots Buzzy Shells. However, Rotating Blocks prevent all but the outside ends from shooting. However, the player can hit Hidden Blocks containing 1-Up Mushrooms can block these. There are also two Pipes that give Buzzy Shells and a Cheep Cheep. In the next area, the player must avoid Lava Bubbles from Pipes and two Cheep Cheeps. There is a Pipe that gives Buzzy Shells in the middle. After another Pipe that gives Buzzy Shells, the player must avoid Hammer Bros. on Mushroom Platforms and two Cheep Cheeps. A nearby POW Block can help get rid of the Hammer Bros. The final area, where the scrolling ends, has two Pipes that spawn Angry Wigglers, another that gives Buzzy Shell, the Warp Pipe back to the main area, an Angry Wiggler outside a Pipe, and three Cheep Cheeps. After taking the Warp Pipe back to the main area, the final Cheep Cheep, an Angry Wiggler from a Pipe, and the Giant Gate can be seen. However, the player can't go back through the Warp Pipe because of the One-Way Wall and a Trampoline with wings on a track shoots the player away immediately.
