Barbie fans can relive an epic scene on the music stage with the Barbie doll "Brooklyn" Roberts from the new movie Barbie: Big City, Big Dreams. When kids lift the microphone to Barbie's mouth, the music will play, her dress will light up, and she will sing along to one of two original songs! When her hand returns to its position, the music will continue to play, but the Barbie doll will stop "singing" until the microphone is lifted again.
