Speed of lightning, roar of thunder … It's Underdog! Two episodes ("The Wicked Witch of Pickyoon" and "The Silver Thieves") from the classic animated series find our canine hero facing enemies a bit different from his archnemesis, Simon Bar-Sinister. First, Underdog faces a witch who captures Sweet Polly after her plane crashes in the forest. Then, he foils a robbery by some phantom burglars and discovers their shocking secret.
