during the All-Star block's Laff-a-Lympics series, which featured 45 Hanna-Barbera characters competing in Battle of the Network Stars-esque parodies of Olympic sporting events. Scooby was seen as the team captain of the Laff-a-Lympics "Scooby-Doobies" team, which also featured Shaggy and Scooby-Dum among its members. Scooby's All-Star Laff-a-Lympics was retitled Scooby's All Stars for the 1978–79 season, reduced to 90 minutes when Dynomutt was spun off into its own half-hour and the 1969 reruns were dropped. Scooby's All-Stars continued broadcasting reruns of Scooby-Doo from 1976 and 1977, while new episodes of Scooby-Doo aired during a separate half-hour under the Scooby-Doo, Where Are You! banner. After nine weeks, the separate Where Are You! broadcast was cancelled, and the remainder of the 16 new 1978 episodes debuted during the Scooby's All-Stars block. The 40 total Scooby-Doo episodes produced from 1976 to 1978 were later packaged together for syndication as The Scooby-Doo Show, under which title they continue to air. Scooby-Doo and Scrappy-Doo The Scooby-Doo characters first appeared outside of their regular Saturday-morning format in Scooby Goes Hollywood, an hour-long ABC television special aired in prime time on December 13, 1979. The special revolved around Shaggy and Scooby attempting to convince the network to move Scooby out of Saturday morning and into a prime-time series, and featured spoofs of then-current television series and films such as Happy Days, Superman: The Movie, Laverne & Shirley and Charlie's Angels. In 1979, Scooby's tiny nephew Scrappy-Doo was added to both the series and the billing, in an attempt to boost Scooby-Doos slipping ratings. The 1979–80 episodes, aired under the new title Scooby-Doo and Scrappy-Doo as an independent half-hour show, succeeded in regenerating interest in the show. Lennie Weinrib voiced Scrappy in the 1979–80 episodes, with Don Messick assuming the role thereafter. Marla Frumkin replaced Pat Stevens as the voice of Velma mid-season. Scooby-Doo and Scrappy-Doo shorts As a result of Scooby-Doo and Scrappy-Doo success, the entire show was overhauled in 1980 to focus more upon Scrappy-Doo. At this time, Scooby-Doo started to walk and run anthropomorphically on two feet more often, rather than on four like a normal dog as he did previously. Fred, Daphne, and Velma were dropped from the series, and the new Scooby-Doo and Scrappy-Doo format now consisted of three seven-minute comedic adventures starring Scooby, Scrappy, and Shaggy instead of one half-hour mystery.
