Episodes in which he is prominent

* The Great Gold Robbery: Plans to steal a trainload of gold, but needed a plan to get Underdog off the train so the gold will be as good as stolen. One member suggests they put grease on Underdog's feet, causing him to slide off the gold train when it is climbing a hill, one member suggests they use firecrackers on Underdog, and one member suggests they put dark glasses on Underdog, but Riff deems their ideas useless. The short member suggests they kidnap Sweet Polly, put her in a free-flying hot air balloon and send her into the sky, in the midst of other free-flying balloons, all with turntables playing records of Sweet Polly screaming for help, and Underdog would spend hours trying to rescue Polly while Riff and his men steal the gold. Riff goes with this idea, and they carry out the plan. Underdog, sensing Sweet Polly in danger, leaves his post and searches for Sweet Polly, only to find the records of Sweet Polly hollering for help, but the real Sweet Polly's balloon had sprung a leak. Meanwhile, Riff Raff and his men had forced the Station Master to reroute the gold train onto the express track, thus making the gold train crash into another train. Underdog manages to rescue Sweet Polly, and stop the trains from crashing.

* The Gold Bricks: Frames Underdog for stealing a truck loaded with gold and Underdog receives a 30-year sentence in prison. Sweet Polly knew Underdog wasn't responsible for the robbery, and tracked Riff to an old house. When she was sent plummeting into a pit, Underdog broke out of jail and rescued her.

When Underdog, powerless without his Energy Pill, arrived at RiffRaffville, Riff Raff and his gang found the chance of becoming famous for defeating Underdog, and challenged Underdog to a gunfight at High Noon. When High Noon finally came, Sweet Polly freed herself, and Underdog regained his strength with his Energy Pill. Underdog emerges victorious in the gunfight.
