Bull's-Eye Banzai

Missile Banzai Bills are a sub-species of Bullet Bills from New Super Mario Bros. Wii. They act like a Missile Bill, although they are bigger and they do not turn around when they miss a target. They are the same size as a Banzai Bill, and they only appear in World 9-3. The player can defeat it by simply jumping on its head or by running into it with a Starman. Also, a Missile Banzai Bill cannot be frozen by an ice ball; it will break the ice and release itself when the ice ball reaches it. Likewise, POW Blocks are useless against them.

Trivia
The Missile Banzai Bill is the only enemy from New Super Mario Bros. Wii to not appear in New Super Mario Bros. U.
