Synopsis

The Driller, Mumm-Ra’s loyal servant who had previously seized Panthro in Spitting Image, reappears to serve his master once more. His current task is to bore a passage from the Cats' Lair directly into the Acid Lake, intending for the corrosive substance to flood in and dissolve the lair itself. The Thundercats now embark on a quest to discover the single element capable of neutralizing the acid’s destructive power.
