Eleanor is the youngest sister of the Chipettes. Eleanor was born in the United States. She has a lot in common with Theodore in terms of body shape and color of attire, but she is braver, more fit and has a better memory. She is blonde with pigtails and has brown eyes in the '80s show, which changed to green in the more recent appearances. In the sequel to the first Alvin and the Chipmunks movie, Ian Hawke tells Eleanor that she has to work on getting taller, so he gives her a pair of heels to make her look taller. Theodore doesn't think Eleanor's heels are very comfortable for her. Eleanor admits that they're not and tells him why she's wearing them. Theodore then procedes to tell her that she looks great without the heels. Then they just exchange glances of affection for one another. Eleanor is very affectionate towards Theodore. In the last Alvin and the chipmunks movie, Alvin and the Chipmunks: The road chip, Eleanor calles Theodore "Theodorable" and giggles as she catches up with her sisters. She also calls his dancing smooth. Eleanor loves to decorate and design clothes, and has a passion for cooking.
