"Robot Repairman Austin has an unexpectedly busy day in futuristic Mega City when all the robots go on a rampage set to roller disco! When the evil Professor Bug (Pablo) starts making all the robots malfunction, it's up to Repairman Austin to save the day in this double-length adventure!"
Austin exits a fence dividing his house from the others' houses and introduces himself as Austin, the owner of a robot repair shop. He asks his toy robot, Robot Roscoe, if he needs any repairs. Roscoe answers with "All systems A-OK", and causes Austin to feel bad. He explains to the viewer that robots never break as he sings "I'm a Robot Repairman". The repairman then starts to walk off to Mega City, a large futuristic community in which robots take on everyday chores and normal tasks.
Austin, along with his robot, Roscoe, enter a white building known as the repair shop. The phone rings, but instead of answering it, goes crazy because someone actually called. Roscoe tells him to answer it, and he does. On the other end, Uniqua's robot is on a rampage! Austin gets into his car along with Robot Roscoe ad head off to Uniqua's futuristic house.
The two repairmen enter the house and see Uniqua's robot, Robot Reba, baking cookies wildly. Uniqua says that she cannot even taste a cookie. They sing "Robot on a Rampage" as Austin attempts to reach Reba's control panel. He succeeds and shuts down the robot. A screw comes out. Just then, they hear screams coming from outside. Tyrone's robot, Robot Ripley, is stealing all the mailboxes off the street. They sing "Robot on a Rampage" again until Ripley shuts down and a screw comes out of him.
They hear another shriek. Tasha's robot, Robot Racquel, is on a rampage in a car. She is driving out of control. Austin jumps on to the floating car and shuts down Racquel. A screw comes out of her. They walk into town, but realize that something's fishy. An evil penguin professor appears on every screen in Mega City and explains who he is while singing "I Am Professor Bug". The citizens and repairman try to escape, but the bugged robots surround the four as Bug watches from the giant screen. The words "To be continued..." appear as the episode ends. Then the end credits came at last.
