The Coolsville bank is robbed. The janitor says that he saw a monster in the vault but nobody believes him and he is accused of the robbery. He's proven right when Scooby finds the monster inside his doghouse.

Scooby and Shaggy go to see a scary film while dropping off Shaggy's baby sister at the sitters, but they are horrified when they find the sitter is hideous. What's worse is that the monster movie character has come to life and an escaped convict is on the loose.
