They paint graffiti on the house and begin to tear down the Gumby's garage. Mrs. Gumby panics and calls her husband at the fire department, who races home in a fire truck and tries to stop the malignant mechanical men. However, he is quickly overwhelmed by the machines and dumped in the trash. Gumby manages to rescue his father but another robot breaks through the wall with a lawnmower and frightens Mrs. Gumby. Gumbo tries to stop a rogue robot who is digging up the flowerbed, but is thrown onto a nearby roof and takes the impact in the groin. Gumby gets him down but not even a wrench can stop the robot (as Gumbo gets it thrown through him). Gumby hijacks a crane and destroys the last robot.
