I've decided I don't want a set of the mini dolls, can't say about the heads as I haven't got one yet but they look to be about the same size as a Barbie's, smaller than a normal Liv but more promising.
Being a Happy Meal toy you can expect a certain level of cheapness, molded on clothes, only the wait, shoulders, and neck move. The bummer is the hat doesn't come off. I tried, there was enough room in the bag, but it went nowhere. Major disappointment that has me off the idea of mini mes for my Livs.
I think a lot of us were hoping for tiny versions of the dolls to dress but we ain't getting that. Splurge on some mini Barbie, Disney Princess, or Dawn dolls if you want dolls for your dolls.
