After Pugsley befriends a thoroughbred racehorse, Gomez and Morticia make him give the horse back to its owners. This depresses him so The Addams Family have a day at the races so he can see the horse again. However, when the horse comes in last, Pugsley overhears the owners plan to send him to greater pastures. He and Wednesday steal the horse to save it, but their parents tell them to give it back. Wednesday asks Lurch and Uncle Fester to dress in a horse costume, and they are taken away.
