David Macpherson explores an hour long episode of Scooby Doo. This tale deals with Cass Elliot owning a haunted candy factory. Only Scooby and friends can save the day. This book examines aspects of the show, the need for guest stars in a Saturday morning cartoon and the joy and pain of limited animation. Mama Cass's Golden Caramel Bar is a funny, thorough exploration of something that was never meant to be closely examined.
