The New Scooby and Scrappy-Doo Show four-year absence. The plots of each episode feature her, Shaggy Rogers, Scooby-Doo, and Scrappy-Doo solving supernatural mysteries under the cover of being reporters for a teen magazine. Each half-hour program was made up of two 11-minute episodes, which would upon occasion be two parts of one half-hour-long episode. The second season of this format, broadcast as "The New Scooby-Doo Mysteries" in 1984, continued the same format, and included six two-part episodes featuring original "Scooby-Doo" characters Fred Jones and Velma Dinkley, both absent from the series for five years. Fred's last name is given as "Rogers" initially in his return appearance
Scooby-Doo and Scrappy-Doo (1979 TV series) threatening cancellation for the show, whose ratings were in decline. ABC was going to choose between two shows-Scooby-Doo or an unnamed pilot from Ruby Spears Enterprises. Therefore, for its 1979–1980 season, "Scooby-Doo" was given a major overhaul, adding the character of Scooby's nephew Scrappy-Doo, voiced by Lennie Weinrib, and changing the name of the show to "Scooby-Doo and Scrappy-Doo". Although still present in these episodes, the characters of Fred, Daphne, and Velma became less essential to the plot and Shaggy, Scooby and Scrappy were the main focus. Marla Frumkin took over Pat Stevens' role as Velma Dinkley towards the end
