Ep. 12: Astro rescues a damaged Martian mining robot whose stolen neutron head causes chaos.

12

A spacecraft crashes on Earth, leaving a burning robot named Goliath. Doctor Elefun contacts Astro to rescue the mining robot from Mars, who possesses a neutron beam in his head. Elefun removes the dangerous component for safety, but it is subsequently stolen. Goliath searches for his head, trying on various other robots' heads in the process. Meanwhile, Daddy Walrus discovers the head being sold at a criminal auction. Skunk Kazi gasses the crowd and takes the head, offering to return it if Goliath destroys Astro. During a fight, a tank containing the head fires on them, burying the combatants under rock. Walrus, posing as Sam Bannister, shoots the tank at the criminals' hideout. Skunk enters the tank and uses the neutron beam against the police. Astro dodges the beam, wrecks the tank, and Walrus knocks out Skunk. Astro returns the head to Goliath, but the two fight over it. The beam discharges, annihilating Goliath.
