Barbie Color Reveal Chelsea dolls deliver an unboxing experience that's full of surprises -- six of them! A doll with a sweet fashion 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 pink Color Reveal Chelsea doll and four bags hiding surprises. Remove them all and fill the tube with warm water, then insert the doll and swirl her around. The water changes color, 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 leotard, but the surprises continueopen the bags to discover a detachable ponytail, a skirt, a pair of shoes and an accessory, like a bottle of sunscreen or a scuba mask. Use ice cold water to change the color of the doll's ponytail hairpiece for another transformation -- kids can repeat this wow moment over and over again.
