The Richie Rich/Scooby-Doo Show The Richie Rich/Scooby-Doo Show The Richie Rich/Scooby-Doo Show is a 60-minute Saturday morning animated package show produced by Hanna-Barbera Productions and broadcast on ABC from November 8, 1980 to November 7, 1981. The program contained segments of "Scooby-Doo and Scrappy-Doo" and "Richie Rich". The "Scooby-Doo and Scrappy-Doo" shorts represents the sixth show in which Scooby-Doo appears. This was the only Hanna-Barbera package series for which "Scooby-Doo" was given second billing and also notable for Richie Rich's debut in animation. With the exception of the "Richie Rich Gems", each episode featured three Scooby-Doo segments and three Richie Rich segments between them.
Scooby-Doo joined with a new Hanna-Barbera show, "Dynomutt, Dog Wonder", to create "The Scooby-Doo/Dynomutt Hour" (the show became "The Scooby-Doo/Dynomutt Show" when a bonus "Scooby-Doo, Where Are You!" rerun was added to the package in November 1976). Joe Ruby and Ken Spears, now working for Silverman as supervisors of the ABC Saturday morning programs, returned the program to its original "Scooby-Doo, Where are You!" format, with the addition of Scooby's dim-witted country cousin Scooby-Dum, voiced by Daws Butler, as a recurring character. The voice cast was held over from "The New Scooby-Doo Movies" save for Nicole Jaffe, who retired from acting
