It's been many years since I saw this show, but as I recall it was a lot of fun with a combination of slapstick humor and clever dialog. I often caught my parents laughing at it. Penelope was a wealthy fashion plate Southern gal and The Hooded Claw (now there's a name!) was always cooking up ingenious ways to destroy her (e.g., explosive pastries called "bombs-bombs") and get his grubby hands, err, claws, on her fortune. He was aided by identical twins, the Bully Brothers, who did everything in unison, even when crying "Oh no!" when a plot backfired on them. But they always failed, often due to the timely intervention of the Ant Hill Gang in a smart car long before KITT came along.
