Barbie Color Reveal mermaid baby dolls deliver an unboxing experience full of surprises -- five of them, including a pet! A sweet mermaid baby figure is guaranteed, but its look remains a mystery until revealed. Open the starfish-shaped case and remove the mermaid baby doll covered in Color Reveal sea blue and three mystery bags. Fill the case with warm water, then reveal the baby doll by dipping and swirling it within! Part of the Color Reveal Rainbow Mermaid Series, each doll represents a different color of the rainbow. Open the three bags to find a pet friend, colorful skirt and a baby bottle or pacifier.
