With the Brooklyn Barbie doll, children can reenact their epic performance from Barbie: Big City, Big Dreams. When the microphone is held to the doll's mouth, music starts playing, her dress lights up, and she sings one of two original songs. If her arm is pressed back down, the music continues, but the Barbie doll stops singing until the microphone is held back to her mouth. Children aged 3 and up can add the Malibu Barbie doll so that the two can make music together and experience exciting stage adventures. The doll cannot stand on its own. Color and design may vary.
