How to Train Your Coward

Shaggy and Scooby become badly injured after a run-in with a monster, and as a result, they decide to quit the gang forever. Before they leave, however, they attempt to find replacements for themselves and provide on-the-job training, which proves difficult when the gang inadvertently drives into a town plagued by a vicious vampire. Shaggy and Scooby also discover that replacing themselves may not be quite as simple as they previously believed.
