Barbie Colour Reveal dolls deliver an unboxing experience that's full of surprises - seven of them! The packaging is part of the fun - pull the strip to remove outer layer and reveal a clear tube. Inside is a mystery metallic blue colour. Reveal doll and four bags hiding surprises within. Remove them all and fill the tube with warm water, then insert doll and swirl her around. Water turns metallic blue, and when doll is pulled out, her features are revealed!
