Olaf is an uncle of Shaggy Rogers and the owner of a resort hotel.
He is a Caucasian male with white hair, mustache, and goatee.
He was so frightened of the U-boat ghosts that he threatened the gang with a gun, thinking they might be the ghosts in another form, so he is probably cowardly and superstitious.
