Boos (Also known as Boo buddies in Super Mario World) are recurring enemies in the Mario series. They are ghosts that were introduced in Super Mario Bros. 3. They are very shy of Mario as they will hide their faces every time he looks at them, but when Mario looks away, they will drift slowly towards him each time.

Newer Super Mario Bros. Wii

In Newer Super Mario Bros. Wii, Boos prominently appear in Pumpkin Boneyard. They can be defeated with a Hammer Suit or Super Star.

Newer Super Mario Bros. DS

In Newer Super Mario Bros. DS, Boos are more common then they were in the previous game, appearing in Ghost House levels and the levels in Pumpkin Boneyard. Their sprites have been slightly modified to resemble more of their appearance in New Super Mario Bros. Wii instead of having their sprites from the original New Super Mario Bros..
