Simon
Simon is "the smart one". In addition to having an IQ just north of Einstein, Simon possesses a very dry sense of humour as well as a keen wit. Alvin exploits Simon for his crazy schemes because he is smart enough to carry them out. In the end, Simon loves Alvin, although he secretly worries that they share the same gene pool. His signature color is blue (originally yellow in Let's All Sing with The Chipmunks, then red in Sing Again with The Chipmunks and then orange in Around the World with The Chipmunks), and he has blue eyes and black glasses; his glasses had blue frames after the 1983 television series' second season up until the show's final season, and in The Chipmunk Adventure. He also has brown fur in the film. He plays the bass, bass clarinet, saxophone, bagpipes, tuba, and drums, among others. He is shown playing the keyboard in the original open for the 1980s series. He was also shown playing guitar in a 1980s Hardee's commercial.
