Help on character for theatre?

For theatre, I'm creating a character out of an animal. My animal is a chipmunk. My human is going to be a secretary who runs around New York doing stuff for her boss, and is quick and a bit ADD. But I need a name. I was thinking Brittany because that's one of the Chipettes names in Alvin and the Chipmunks, but I'd like something that means something to describe a chipmunk.I'd also like any additional help that would make my character more believable. Thanks :)
