This Barbie Dreamtopia Rainbow Magic Mermaid Doll can change color and adds colorful fairy wings to the imagination. The Barbie mermaid doll shines in a neon rainbow look. She has a tail in bright, vibrant colors, a top with ocean accents, and wears a tiara in her rainbow hair. Ready for a magical color change? Simply dip the Barbie doll in warm water, and her hair, top, and tail will instantly change color. The new colors resemble a rainbow of pretty pastels. When dipped in icy cold water, she returns to her original neon look. This transformation can be repeated as often as desired. The doll cannot swim or stand on its own. Color and design variations may occur.
