Banzai Bill Cannon

Banzai Bill Blasters (also known as Banzai Launchers) are large Bill Blasters in New Super Mario Bros. Like Bill Blasters, they slowly shoot Banzai Bills. These Bill Blasters appear only in a few levels of the New Super Mario Bros. and help the player reach the tops of the flagpoles.

They also make an appearance in Super Mario Galaxy on the final level, Bowser's Galaxy Reactor. They also appear in New Super Mario Bros. Wii, Super Mario Galaxy 2, New Super Mario Bros. 2 and New Super Mario Bros. U.

In Mario and Luigi: Bowser's Inside Story, before Fawful took over Bowser's Castle, Private Goomp, Corporal Paraplonk, and Sergeant Guy were able to salvage a Banzai Bill Blaster, and escaped with it. Bowser later encountered the group carrying the blaster through the forest, and they told him that they were going to launch a Banzai Bill at the castle, though he then learned that they had no Banzai Bills.

After Bowser recovered one from Wiggler, they launched it at the castle, though before it could make contact, Midbus had the castle float into the air, efficiently dodging the Banzai Bill.

Trivia

 * There is only one visible Banzai Bill Blaster in New Super Mario Bros. Wii. It appears in world 7-4.
 * In New Super Mario Bros. Wii, through hacking methods, it is possible to have a Banzai Bill Blaster fire Missile Banzai Bills, but they will behave in an erratic manner when fired that way.
