The 13 Ghosts of Scooby-Doo

While at a paranormal convention, the gang is chased by the evil Reflector Spectre and his henchmen, Weerd & Bogel (the two comic ghosts from the premiere episode). It's up to the gang to capture the ghost and solve the mystery of the disappearance of a maid who was taken into the Spectre's mirror world by mistake.
