This 4-pack Barbie doll and vehicle set includes small-scale versions of the Barbie DreamCamper, Dream Plane, Care Clinic, and Beach Bug Convertible. Each vehicle comes with a 1.5-inch doll and features color-change elements. Apply cold water to activate the color change on pieces like the camper's pool or the convertible's surfboard, then use warm water to revert it—repeatable for continuous play. The vehicles have functional parts such as doors and accessories to enhance role-play and storytelling. The mini dolls have articulated waists for sitting and driving poses and attach to Mini Barbie Land playsets via a heart-shaped base (playsets sold separately). This set offers multiple ways to expand imaginative play scenarios.
