The Scooby Doo TV cartoon show was a hit with young kids during the '70s and '80s. The characters are Scooby- and Scrappy-Doo and their friends Fred, Daphne, Velma, and Shaggy. Scooby and Scrappy are detective-type dogs that continually get into scrape after scrape. In this episode, when Shaggy finds he's due an inheritance, he, Scooby-Doo and Shaggy-Doo travel to a creepy mansion where they meet the Boo Brothers.
