The level begins starts in a wrap-around area heavily based on a course in Mario Bros., with similar platforms and Koopa Troopas acting as Shellcreepers. In the area, there are four ? Blocks that give power-ups. When enough coins have been collected, a golden Warp Pipe appears. It takes the players to an area with two Hammer Bros. and Brick Blocks, along with the Goal Pole.
