Fred lives in the fictional prehistoric town of Bedrock, a world where dinosaurs coexist with modernized cavepeople and the cavepeople enjoy "primitive" versions of modern conveniences such as telephones, automobiles, and washing machines. Fred's trademark yell is "yabba dabba doo!", this phrase was originally his club's cheer; later a phrase adopted as part of the theme song from the third series on and used in the 1994 live-action Flintstones movie.
