Together, the Chipmunks and Chipettes shared a variety of adventures, perhaps the most exciting of which was their balloon race around the world. Over the years, each of the Chipettes engaged in on-again-off-again relationships with their Chipmunk counterparts-- Simon with Jeanette, Theodore with Eleanor, and Alvin with Brittany. However, the relationship between Alvin and Brittany rarely went smoothly, as their similarly aggressive, egotistical personalities often clashed, in contrast to the more mellow interplay between Simon and Jeanette or Theodore and Eleanor. Alternatively, they were also shown to date human boys, just as the boys often showed an interest in human girls. It is notable that the Chipmunks and the Chipettes inhabit a relatively realistic world, in which theirs is the only sapient species aside from human beings, as opposed to a world full of anthropomorphized animals.
Eleanor is the youngest Chipette. She is considered the female counterpart of Theodore, but is shown to be much more athletic. Out of the three Chipettes, she is the one who is most likely to willingly take part in a sports activity. Still, she is the chubbiest of the sisters due to her love for creamy food and cooking. Eleanor is much less timid than Jeanette, and is always happy to stand up to Brittany when she thinks something is not right. Eleanor has blonde hair, brown eyes, her hairstyle is a pair of blonde pigtails, and her signature color is spring green. In the 2009 film, she is voiced by actress Amy Poehler.
It is worth noting, however, that the Chipettes of the cartoon series (Brittany, Jeanette and Eleanor) appeared on the small screen before appearing on any albums. Their first appearance on the Chipmunks album was on 1984's Songs From Our TV Shows which was released on March 4, 1984, nearly seven months after the Chipettes debuted on the first episode of the Alvin and the Chipmunks television series on September 17, 1983.
Unlike their male counterparts the Chipmunks, the Chipettes have no fur covering their entire bodies but instead possess humanlike hair on their heads, which can be styled into different hairstyles for each girl; a stylized ponytail for Brittany, a bun for Jeanette, and two pigtails for Eleanor. However, in the Squeakquel, the Chipettes had to be redesigned yet again so they would better resemble real chipmunks, so they were given full fur coats, but their animators and designers still left a small amount of humanlike hair on the girls' heads, though the Chipettes' hairstyles differed slightly from their usual hairstyles in the animated series. Now Jeanette had a ponytail that was slightly shorter than Brittany's and on top of her head more, but each Chipette's new fur coat was made the same color as their hair in the series, though not exactly the same shade.
