Another problem is how Sheridan didn't list Scooby-Doo and Scrappy-Doo with Fred, Daphne, and Velma, as continuity to the film, but this means it unnecessarily creates a new continuity where Scrappy randomly pops up in 13 Ghosts of Scooby-Doo, which is alluded to in the opening credits of the film, which is why Velma wouldn't know who Scrappy is. Massive justification for a massively pointless retcon of dubious reliability just to create a more conflicting timeline and bad joke. Which is why they shouldn't have had Scrappy one bit.
