Enjoy all 16 episodes (I'm amazed there were only that many!) of probably the best 70s cartoon series. The animation is of course fairly basic, but the characters and stories are anything but. The hero is Penry Pooch, a dog who works as a janitor at a police station. He listens in on the crime reports as they are radioed in then transforms himself into a superhero: a kung-fu fighting... idiot. The humour of the set-up is that Penry is utterly incompetent and all the bad advice he gets from the 'Hong Kong Book of Kung Fu' doesn't help much either, but like Inspector Clouseau he always keeps his dignity. Ultimately he always captures the villains and solves the crimes, but he does so either through complete luck or by the actions of his clever (but never appreciated) side-kick Spot the cat.
The series stands up well today, perhaps because unlike the other good Hanna-Barbera cartoons it has been seen only rarely since, so it still feels fresh. Obviously it's not a masterpiece to be put up there with the better modern computer animated films and so some rose-tinted nostalgia is required to enjoy fully. But the comedy is often quite clever, relying less on slapstick and more on inventive ideas and character-based humour. The voices are also well done and there are many good running jokes and nicely-played relationships such as the one between Penry and Rosemary, who received the calls at the police station and adores Hong-Phooey but like Lois Lane is oblivious to Penry. All in all, the show deserves its reputation as being the last great HB cartoon series.
