"Scooby-Voodoo Krewe/Costume Caper"
Scooby-Voodoo Krewe
Scooby and the gang arrive at a Marti Grais party and are confronted by a Voodoo Witch Doctor who kidnaps Velma by mistake. The gang tracks down Velma who reveals the kidnapper as Anton Duchampe, who was trying to kidnap the daughter of a rival businessman so his own daughter could be crowned Queen of the Ball. Scooby uses a flower allergy to expose Duchampe, who is hiding in a room full of Voodoo Witch Doctors.
Costume Caper
While Fred and Daphnie are away, Velma does some research into the villian's costumes they have collected during their mysteries and notices that most of them came from the same place, The Horne Costume Factory. Velma, Shaggy and Scooby go to check out the factory when they meet the owner, a nice old lady who has no idea what her costumes have been used for. So Velma spares her the humiliation and decides to get a catelog so they can tell if the next villian they run into purchased a costume from Horne. But when the catelog arrives, she is surprised that the new line of costumes look like her, Shaggy and Scooby.
