However, she is very shy and clumsy.
 * Eleanor Miller (voiced by Vanessa Bagdasarian): Eleanor is the youngest sister of the Chipettes, and she is Theodore's counterpart. She shares his love for food and cooking. But she is more athletic, more intelligent, and more likely to stand up to Brittany than Theodore is to Alvin.
