These fantastical Barbie dolls have colourful shimmery hair that can get even more fantastical! Each comes with accessories for an instant transformation into a magical character -- a unicorn or a mermaid. The transformation is easy – simply add a t-shirt and a headband, then accessorize and style. Barbie doll wears a shiny iridescent dress, silvery heels and earrings. Put on the t-shirt with the unicorn graphic or use the one with the mermaid, then add the matching headband. The unicorn hairpiece has a horn, ears and three colourful hair extensions; the mermaid tiara features stars, shells and two teal hair extensions. Young creatives can use the brush, hairbands and barrettes to style her look even more. An additional pair of shoes expands the storytelling.
