CBS had canceled Scooby Doo in August of 1976 and in its place was a similar show the network had hoped would be as successful as Scooby. Didn't pan out that way as Scooby was on ABC, and outside of Bugs Bunny, he still ruled Saturday morning.
A pity because Clue Club wasn't that bad of a show and that can be chalked up to the kids who had a neat chemistry about them and the dogs, Woofer and Wimper. The show stealer is most certainly 13-year-old Dotty, who is equally as smart as she is cute, and always shows up with an alibi as to why she's at the scene of the crime just as Larry is pointing his "J'accuse!" finger.
Clue Club may be an obscurity by today's measurements, but still in 1976 it was a pleasant way to spend a half-hour.
