|The Munsters' Revenge|
- Fred Gwynne as Herman Munster
- Al Lewis as Grandpa
- Yvonne De Carlo as Lily Munster
- Bob Hastings as Cousin Phantom of the Opera
Herman Munster and his family visit a Wax Museum and find that there are wax figures of themselves, except Marilyn, in the museum. Herman and Grandpa are then accused of many crimes that they didn't commit (the wax figures did them).
While trying to clear their names, Herman and Grandpa discover that the wax figures are really robots. An ancient Egyptian prince plans to use the robots to steal a mummy's treasure.
Herman and Grandpa foil the plot with help from Marilyn, her new boyfriend, and cousin Phantom of the Opera.
- Like most stereotypical vampires, Grandpa has a weakness to crosses (specifically crossed fingers) which give him heartburn (much like wooden stakes and garlic), however in the original show crossing fingers had no effect on him and even Grandpa himself crossed his fingers in the second season.
