Cat Bullet Bill

Cat Bullet Bills are a sub-species of Bullet Bills powered-up by a Super Bell that appear in Super Mario 3D World.

Like normal Bullet Bills, Cat Bullet Bills are fired from Bill Blasters. However, unlike normal Bullet Bills, Cat Bullet Bills will lock onto, and follow the player, making them similar to the Missile Bill. However, unlike Missile Bills, Cat Bullet Bills always follow a horizontal path; they can't travel vertically.

Cat Bullet Bills will sometimes drop a Super Bell when defeated. In the level The Bullet Bill Express, Cat Banzai Bills appear, which act similarly to Missile Banzai Bills.

Cat Bullet Bills reappear in Captain Toad: Treasure Tracker.
