The Color Reveal Chelsea series got a couple new faces, made in hard plastic. This is due to the color changing feature. The Mermaids has rooted hair, hence regular soft heads, but when the whole doll is dipped in paint, the head is made of hard plastic. So far the kids all have the same face with the hair sculpted differently. These heads doesn't have any dates - just as Barbie doesn't, so the copyright year is based on the whole body.

The second Color Reveal girl sculpt has molded bangs, while the back of head has the hair "gathered up" to the ponytail hole
