Living Ooze is a mass of talking ooze on Third Earth located near a bend on the River of Despair. It aims to destroy all that is green, clear, bright, and white. When Lion-O mistakenly releases Plutar (and others) from captivity, Living Ooze teams with the criminal to destroy Third Earth before Mandora and the Thundercats can stop them. The Living Oooze was voiced by Bob McFadden
