Mumm-Ra creates a museum whose paintings and statues come alive as the Thundercats' more formidable foes. As Lion-O and Snarf prospect for Thundrillium, Mumm-Ra turns into Dr. Dometone and lures Lion-O to the deadly museum. Snarf fails to stop Mumm-Ra and rushes back to the Lair for help. Inside the museum, a painting of Safari Joe comes alive and ambushes Lion-O. Lion-O defeats Safari Joe only to face Ratar-O, who jumps out of a painting and attacks. Ratar-O traps Lion-O in the electrical force of his Electro Sais, but Lion-O breaks free. Mumm-Ra appears and douses Lion-O with Warp Gas. The gas makes Lion-O too scared to fight, so he runs. Meanwhile, the other Thundercats set out in the ThunderTank to rescue Lion-O. Once within Mumm-Ra's museum, they decide Lion-O must be inside one of the paintings. Wilykat and Wilykit enter the Safari Joe painting. The other Thundercats drive the ThunderTank into a painting of Spidera, who traps the ThunderTank in her webs. Safari Joe captures the Thunderkittens in sacks. Lion-O revives to confront Mumm-Ra, who transforms into a duplicate of Lion-O. Lion-O defeats his own duplicate. Then he uses the Sword to free the other Thundercats from the evil paintings.
