An undercover operative is convinced that the Addams family are spies.
Pugsley wants a horse for his birthday celebration, so the Addams Family go to Kentucky to buy one. They choose a worn-out old nag named Bones, but Granny’s cooking does her so much good that she becomes a fast runner again and is ridden by Pugsley to victory at the Kentucky Derby.
Uncle Fester suddenly grows hair on his head and no barber-based tools can remove it since the hair is hard. The other family members work to find a way to remove the hair from Uncle Fester’s head.
