Bullet Bill

Bullet Bills are enemies from the Mario series. In the Crystal Screen and New Wide Screen versions of the Game & Watch game Super Mario Bros, they fly in a straight line and attempt to hit Mario, which will make him lose a life unless he has a star. The appearances are different between the two different versions. The Crystal Screen Bullet Bills look more like Banzai Bills, while the ones from the New Wide Screen version look more like Bullet Bills.
