Chip and Dale are two chipmunk cartoon characters created in 1943 at Walt Disney Productions. Their names are a pun based on the name "Chippendable". An easy way to visually tell them apart is that Chip has a black nose like a chocolate chip as a way to help people remember who is who with two centered protruding teeth. Dale has a big red nose and his two prominent buck teeth exposed.
The voices of Chip and Dale are provided by James MacDonald, Dessie Flynn, Tress MacNeille, and Corey Burton.
