A motorcyclist called Rocky has an accident outside the mansion. The Addams Family takes him in to recuperate. After seeing Kitty Kat, Marie Antoinette, and Cleopatra, he tries to leave but his leg still hurts. Morticia performs first aid with boiling oil, a stout rope, leeches, and the pillory in the play room. Eventually Rocky forms a reluctant bond with the family, and agrees to attend a reunion birthday party with his father.
