World 5-5 (New Super Mario Bros. 2)

 is the fifth normal level of World 5 in New Super Mario Bros. 2. This level is based upon Bullet Bills, and also includes Snake Blocks.

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.
