Underdog S02 E52 RiffRaffville, Part 4

A western song plays during this cartoon as Riff Raff challenges Underdog to a gunfight at noon. The townspeople are too scared to help Underdog- it looks like the end- but Sweet Polly frees herself and gives Underdog his ring. He takes his energy pill and beats Riff and his gang giving the people their town back.
