The family at 1313 Mockingbird Lane is a little... different. Dad Herman looks like Frankenstein's monster; mom Lily and her dad, Grandpa, are vampires; and son Eddie is a werewolf. Poor Marilyn, their niece, is the odd one out -- she's just a normal girl. And the family doesn't like to call attention to her unfortunate looks.
Grandpa concocts a potion to provide instant talent for Eddie when Herman forces him to take up the trumpet.
Two of Marilyn's teachers decide to present Herman to the scientific world as the only living prehistoric man.
Dr. Frankenstein's great-grandson arrives with cousin Johann, who looks exactly like Herman.
Grandpa creates a robot playmate for Eddie.
