Underdog (1964)

Season 2: Episode 39

The next plan is camouflage and sabotage. They wreck the museum's equipment and disguise themselves as two columns, a statue and a wastebasket to grab the painting while Underdog is fixing the broken museum equipment, after taking his Super Energy Pill. But Underdog stops them. Riff Raff's last plan might not only work, but he could also find out Underdog's secret identity.
