Barbie is a smooth-talking Barbie doll who is also Molly's doll. Many Barbie dolls appeared in the previous films, but one Barbie is a protagonist in the third film. She has a ponytail decorated in a pink scarf with a matching belt around her waist and the same color of high heel shoes on her feet and wears a turquoise sleeveless unitard with striped legwarmers. Throughout the film, she falls in love with Ken. However, a problem is Barbie is a protagonist and Ken is an antagonist. But by the end of the film, things eventually work out between the two, and they become co-leaders of Sunnyside.
