Chuck is Dave's second cousin, twice removed on his father's side. He is a southern boy with a distinct southern accent. As a result of everyone telling him he can't do anything, Chuck lacks self-confidence. This doesn't prevent him from trying new things. Though he's great at following directions, he still fails to be successful at any of the tasks The Chipmunks give to him. When he's disappointed in himself, he plays his guitar and sings. Believing his talent was nothing special, he failed to see he could do something.
