Destroyer Ants/Swamp Monster

A lightning storm causes a nest of giant ant eggs to hatch. The giant ants cause havoc and destruction and Zandor and the Herculoids must put an end to them.
A hideous monster emerges from a swamp and goes on a rampage, destroying anything it comes in contact with by its radioactive touch. It eventually traps Dorno and Gleep in a cave, and it is up to Zandor and the rest of the Herculoids to rescue them and defeat the creature.

Mission of the Amatons/Queen Skorra

Amak and the Amatons come to the planet and place control collars on some animals. When their efforts to enslave the Herculoids fail, Amak tries to kill them. Gloop and Gleep save the day by turning Amak's stun turret on him, causing his ship to crash.
Queen Skorra unleashes a mud/lava creature which they eventually defeat, but Skorra plans to force them into exile by sending her drones to capture Gleep, Gloop, Tara, and Dorno. They defend themselves long enough for Zandor and the others to return and drive off the drones. Skorra launches a mega-shield missile and closes the mega-circle to destroy everyone, but Tundro creates a smokescreen while the others make a tunnel to escape and then send Skorra running.
