Clue Club was a 30-minute Saturday morning animated series produced by Hanna-Barbera Productions from August 14, 1976 to September 3, 1977 on CBS. Clue Club only had one season’s worth of first-run episodes produced, which were shown on Saturday mornings on CBS, which had replaced Scooby Doo.

Here is part the show, The Paper Shaper Caper.

Similar in format to Hanna-Barbera’s successful Scooby-Doo, the show centers around four adolescent friends who open a private investigation agency out of Larry's suburban residence. They are: Larry, 19; Pepper, 18; D.D., 16; and Dotty, 13. They solve mysteries with the help of their two talking hounds, Woofer and Wimper. The dogs only talked to each other & the camera, they were not understood by the human characters.
