When originally aired and on early home media releases, episodes from the second season onward plastered a shot of Scooby and Shaggy running and then stopping to cower (taken from
The Ghoul, the Bat, and the Ugly (1979)) over the original shot of Scrappy carrying Scooby into the waiting room where the whole gang were waiting (
Lennie Weinrib's voice however was not re-dubbed - meaning his distinctively different Scrappy voice continued to be heard for several more seasons). Subsequent re-runs and home media releases oddly use the first season opening titles, creating an inconsistency as Fred, Velma and Daphne were no longer appearing.
