Tom and Jerry have fun at the circus and then show their acrobatic talents on a tightrope. They get into trouble with an ornery lion and are chased from the Big Top by the feline's friends. When the defend themselves by spraying the lions away with an elephant's trunk, they accidentally flood the circus but are able to float away unscathed.
Tom and Jerry are hoboes, but the city is demolishing the hobo camp. They hop a ride on a freight train. The train comes to a lumber camp, where the Chinese cook has just prepared a huge platter of roast chicken; he invites the train people to eat, but hundreds of bums descend. He chases them off, into a log slide, and they end up right back in the original camp.
Tom and Jerry are captured by cannibals while dancing and engaging in musical hi-jinx in the jungle. Can Jerry save their lives by impressing the chief with his yodeling skills?
Tom and Jerry work as piano tuners. After seeing them at work and several creative ways of tuning a piano (such as removing the offending key and cutting the key itself to a shorter length), the two attend an opera singers performance. The singer passes out when the piano plays a wrong note, and Tom and Jerry are pressed into service to re-tune the piano. After pulling the offending key from the keyboard like a bad tooth, the two give the opera audience a jazz piano performance, with the now recovered opera singer joining in.
