You Oughta Be in Pictures

S1, E6: Spydra is annoyed that none of the world's great portraits show her lovely face. So she steals the Mona Lisa and kidnaps famous Parisian Painter Vincent Van Stop-n-Go to repaint the portrait to look like her. Gadget Boy, Agent Heather, and G-9 track her down too late to save Stop-n-Go. It takes all their combined efforts, gadgets, and some invisibility powder to steal the painting back... just in time for its restoration unveiling.
