Barbie Dreamtopia Rainbow Cove Brush FRB12/FRB13 It's magical hair play with this Barbie princess doll whose bodice lights up and plays sound when her extra-long hair is brushed with the included magnetic brush. Because when you enter Dreamtopia with sisters Barbie and Chelsea, you wake up to a world where dreams become reality! Barbie doll wears a princess outfit inspired by her kingdom of Rainbow Cove with a pink bodice and long skirt with rainbow print. The brush matches in a pretty pink. Use it to style Barbie doll's seven inches of hair -- as you brush her hair, lights and sounds are activated via magnetic technology. A cool pattern appears as her bodice lights up, and one of the sound sequences includes the Barbie Dreamtopia theme song. It's a fun wow moment!
