The Scooby-Doo Detective Agency was the name Mystery Inc. used while they were preteens living in their hometown of Coolsville. It was also later used as the name for the older freelance investigative journalists, comprised of Scooby-Doo, Shaggy Rogers, and Daphne Blake. This incarnation had Scrappy-Doo, but not Fred Jones and Velma Dinkley, although they would appear sporadically to help out when they could (either together or separately).
