Boos are a type of white, spherical floating ghost with menacing, normally open mouths. They have large tongues and small flipper like arms. Boos often have shy personality, and cover their faces when someone looks directly at them. They will uncover their faces once the subject turns around, stalking. 
King Boo is not shy. King Boo is very big.
