Unga bunga! Young amateur sleuths Dee Dee, Brenda, and Taffy had no idea that they'd be freeing the world's first superhero from a frozen glacier, and the Cro-Magnon crimebuster (voiced by Mel Blanc) had their backs as they solved mysteries on Saturday mornings on ABC over 1977-1980. All 40 episodes from "Scooby's All-Star Laff-a-Lympics," "Scooby's All-Stars," and "Captain Caveman and the Teen Angels" are collected in a two-disc set. 7 2/3 hrs. total. Standard; Soundtrack: English Dolby Digital mono.
