Scooby-Doo! and the Curse of the 13th Ghost

Yes, I really did enjoy this movie because I love me some Scooby Doo and the gang! Was glad to see some of the "Old Characters" from the "Thirteen Ghost of SD", but Flim Flam was the only one who brought up Scrappy. Then Velma was like, "Who is a Scrappy?" First of all, if the writers would of look at all of the Scooby Doo shows, they would have known that Scrappy had first join the Scooby Gang back doing "The Scooby and Scrappy Show." It was some other stuff that didn't make sense to me in this movie, but I'm not going to discuss it. Smh I think that they should bring Scrappy back because he was Scooby's nephew for goodness sake!!!!
