World 7-1 (New Super Mario Bros.)
The player will start on a small area of land, and the whole level is mostly moving platforms. Flame Chomps are common in this level. Toward the end, the player should move along the upper moving platform. At the end of the level, the player should take the moving platform to gain more height to reach the flagpole.
Because the second and third Star Coins are found on different paths, this is the only level where the player cannot collect all of the Star Coins in one run.
