Alvin Smith, an alternative identity of Alvin Seville, is the main protagonist in The Chipmunks Go to the Movies episode Bigger!


As a kid, he was seen wearing a red shirt, blue hats, and watch on his wrist. As an adult, he wears a white dress shirt with a dull blue tie.


Alvin Smith wants to be a grown-up and finds a magic jukebox and makes a wish there, making him bigger. He, as an adult, firstly acts like a boy playing with toys, then later acts like an adult, calling Simon and Theodore's song demo "a kids' song." Later he wants to become a kid again as he thinks being a kid is easier than being a grown up.
