These Barbie Color Reveal sets deliver the ultimate unboxing experience with 25 surprises that include repeat color-change features, a pet, two outfits -- one of them a fantasy look -- and a Barbie doll to play out magical transformations over and over again! Find fun transformative themes like mermaid, fairy and unicorn. Lots of pieces inspire lots of play. The packaging is part of the fun -- remove the bags, with their hidden contents, and the tube; pull the tube's strip to remove its outer layer. Inside is a clear tube containing a mystery Color Reveal doll. Fill the tube with warm water, then insert the doll and swirl her around. The water changes color -- but not the color you expect, 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.
