Layout
Mario begins the level next to Snake Blocks that can be jumped on to reach a Warp Pipe. Jumping onto the platform to the right of the Snake Blocks causes a group of coins to appear under the pipe. When the pipe is entered, Mario enters an area with a Bill Blaster Turret and a group of ? Blocks over a Snake Block. Another Snake Block with a Bill Blaster Turret and a Coin Block above it is then found. Mario then arrives at a Bill Blaster Turret found next to a Brick Block containing a 1-Up Mushroom. Another Bill Blaster Turret is found, surrounded by two rising walls of Snake Blocks. Mario then arrives at the Checkpoint Flag, which is nearby four ? Blocks, one of which containing a power-up. Two Snake Blocks with Note Blocks in between them are encountered, along with a Bill Blaster Turret. A Red Ring is found above Note Blocks, in between two Bill Blaster Turrets. More ? Blocks and a Bill Blaster Turret are found, followed by a Banzai Bill Cannon. The Goal Pole is then found.
