Barbie Colour Reveal Doll (3-10 Yrs) - Available at M&S
This beautiful Barbie mermaid doll has a surprising secret. Place the mermaid in the clear tube, fill with warm water and watch as she magically reveals herself. There are seven looks to collect. Open the four bags to find a fin, necklace, brush and a sponge that can be dipped in water and used to change the colour of the doll's hair, eyes and lips. The best part is that children can relive the magic over and over again. Suitable for children 3-10 years.
