Banzai Bill

Banzai Bills are an extremely large variety of Bullet Bills. They are black in Super Mario World, but in New Super Mario Bros., they have a more purple hue. Both have a shark-like smile. Although they may seem impossible to defeat, they can be destroyed by simply jumping on top of them.

Banzai Bills are also a major threat in Super Smash Bros. Melee, in the stage Princess Peach's Castle. Banzai Bills randomly enter the battlefield, colliding into the castle. They soon detonate and cause massive damage to anyone caught in the explosion.
