The Scooby & Scrappy-Doo/Puppy Hour The Scooby & Scrappy-Doo/Puppy Hour The Scooby & Scrappy-Doo/Puppy Hour is a 60-minute Saturday morning animated package show co-produced by Hanna-Barbera Productions and Ruby-Spears Enterprises and broadcast on ABC from September 25, 1982 to December 18, 1982. The show contained segments of "Scooby-Doo & Scrappy-Doo" (Hanna-Barbera), "Scrappy & Yabba-Doo" (Hanna-Barbera) and "The Puppy's New Adventures" (Ruby-Spears). The first half-hour consisted of a 7-minute "Scrappy & Yabba-Doo" episode placed between two 7-minute "Scooby-Doo & Scrappy-Doo" episodes followed by a 30-minute episode of "The Puppy's New Adventures" in the second half-hour. The Scooby/Scrappy-related shorts were written, storyboarded and voiced at Hanna-Barbera, but
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
