The cartoon begins with a canary in his cage and a parrot singing. The canary wants to get out of his cage, but is locked inside. Then, their owner arrives. But she accidentally left the cage open. Then, the canary flies out and goes outside. He descends into a garden and a cat slyly sneaks up on him. The weather then gets windy as a thunderstorm arrives in. Then, the cat chases the canary around the garden. Suddenly, a lightning bolt strikes the cat's tail and he runs away screaming in agony. Realizing the outside world isn't as safe as his cage, he flies back home and the canary sings as the cartoon ends.
- This is the first short of the Happy Harmonies Series. The opening titles say A METRO COLOR CARTOON because Harman/Ising didn't know what to call it at first. The next short, The Old Pioneer would introduce the new title HAPPY HARMONIES.
- This is the first MGM short. After Happy Harmonies ceased production, MGM moved to stronger subjects such as Tom and Jerry, Tex Avery, and Barney Bear. Cartoons would become a staple of MGM's programming, until 1967.
- This short fell into the public domain in the United States in 1962 due to MGM failing to renew copyright in time. A black and white faded 2-hue color print does exist in bad quality and it is censored. The original print is on YouTube.
- It is unknown if a dubbed version exists.
- A print has HAPPY HARMONIES in place of A METRO COLOR CARTOON, however, this is probably a recreation.
