This beautiful mermaid changes color like the sea, transforming hues from head to tail with water of different temperatures. Her hair is restyled with three colors-pink, purple and blue-and her tail changes to multiple colors that vary with the water temperature. Her seahorse squirt-toy friend can be used to create even more magical transformation on her tail, especially when filled with water of another temperature. Designed for unique movement, girls can also bend this mermaid doll's tail to create a realistic swimming motion and discover the Barbie Fairytale Magic. Includes mermaid doll, seahorse squirt toy, brush, tiara and necklace.
