The Princess and the Popstar 2 in 1 Transforming Tori doll, twist her hair and it changes to pink (second photo), dress can be opened or closed for different looks. I can't get her to sing, I'm going to try to pick up new batteries and will update the ad tomorrow but please send me a message if you're interested.
Barbie Mariposa (I think?), twist and her skirt looks like butterfly wings (third photo).
Singing Rapunzel - I See the Light song works!
