"Where Treads the Living Totem!"
The FF receive a letter from Wyatt Wingfoot, who has returned to his tribal lands only to find out that they are being terrorized by an ancient spirit called Toomazooma. The FF go out to investigate as they learn that it is not a real spirit but a robot deployed by a Russian Oil Company to scare the natives off the land so they can harvest the oil under the tribal grounds. Together with the tribe, the FF fight and destroy the robot.
