When Juke approaches Darwin and Gumball with a frantic message, the boys are unable to understand him because he only speaks in boombox noises.
While I can’t recall the last show that used this plot, episodes where characters are trying to decipher a message used to be somewhat common. The clichés of old are becoming less cliché as the years go by, but “The Boombox” dusted that one off and got some good mileage out of it. This was a solid episode. It continued this season’s trend of giving side-characters more of a role, and while I never found Juke to be particularly interesting, his inability to communicate did create some amusing scenarios for the boys. The scene where they used online translators, for example, which poked fun at both their uselessness and gave cause for a long scene where the entire school began to think that the teacher had retired. The episode was also sharply written, with a few jabs being taken at people who help others for the sake of feeling superior to them. The writers for The Amazing World of Gumball don’t often get the credit that they deserve, as the show’s visuals tend to stand out at the forefront, but they can be proud of what they did with this episode.
