Ep 40. Jungle Planet

Professor Cordac, the most brilliant scientist in the universe, disappears on the Jungle Planet, and Space Ghost investigates, only to fall victim to the same villain, the insidious Mind Taker, who drains the intellect from his captives and uses it to boost his own formidable mind. He plans to add Space Ghost's mind to his collection! Fortunately, when Space Ghost told Jan and Jace where he was going, he failed to tell them not to follow him - or so they reason. And that's lucky, because they're able to distract the Mind Taker and his thugs seconds before the fiend can drain Space Ghost's mind!
