Barbie Colour Reveal dolls deliver an unboxing experience that's full of surprises -- seven of them! A gorgeous mermaid doll is guaranteed, but each doll's look remains a mystery until revealed. The packaging is part of the fun -- pull the strip to remove the outer layer and reveal a clear tube. Inside is a mystery metallic teal Color Reveal doll and four bags hiding surprises within. Remove them all and fill the tube with warm water, then insert the doll and swirl her around. The water turns teal, and when the doll is pulled out, her features are revealed! Each doll has a different combination of eye color, hair color, skin tone and decorated bodice, but the surprises continueopen the bags to discover a mermaid fin, a necklace, a brush and a small sponge. Dip the sponge in ice cold water and use it to transform the doll's hairstreaks and face -- her eyes and lips change color! With the use of warm and ice cold water, kids can repeat this wow moment over and over again.
