It's a Land of the Lost Thanksgiving!
The Pakuni and the Marshall's learn a lesson in cooperation while foraging for food during a drought. The mythical elements of the Plymouth Thanksgiving is reversed in this episode though. Instead of the natives saving the Pilgrims from starvation it is the newcomers who save the day. At least it was from working together and not exploitation.
Based on the old folk tale, the Stone Soup episode of The Land of the Lost was first broadcast in December 1974.
