I used to have a doll that had a sun shape on its cheek and when you touched it,it would become a heart.It is not Sailor moon.The only thing I remember was that it had a plastic head and cloth body.Also came with certificate like cabbage patch kids dolls.I got it for Christmas in 1992

Was it a cabbage patch baby. And you didn't know the sex until you opened the box. I know what your talking about but I can't think of the name but try to Google cabbage patch baby.
