They can't!!! This is one of my favorite "Scooby-Doo" shows out of all of them. This show is quite a bit different from the past "Scooby" shows because in this show, Scooby, and the gang have to get 13 ghosts back into a chest that Scooby opened by accident, no guy in a costume here, these are actual ghosts (which is cool, and it was a great step for "Scooby-Doo"),and this show is more wackier than previous "Scooby-Doo" shows, which is cool. Anyways, this show also featured a new character in Flim-Flam who was OK, and Daphne, and Shaggy wore different clothes in this show as well. Vincent Price did a great job as Vincent VanGhoul, and those 2 ghosts who were always trying to stop Scooby ad the gang from getting the ghosts back into the chest were cool too. Bottom Line: A great "Scooby" show!!!
