King Boo shares his karts with the other heavy characters in Mario Kart Wii. Try to take away his crown, and he will haunt you for the rest of your life! So, with that being said, what makes him different from a regular Boo? To fit his role as the king of the boos, King Boo is noticeably bigger, and he has a royal golden crown with red and blue jewels encrusted in it. He always has his mouth open in a haunting manner, so his tongue and sharp teeth can be seen quite clearly. He has a round shape with two arms on either side of his body (or face, it's tough to tell), and he has a tail. His body is a ghostly white color, most likely because he is a ghost.
