no clue on price but there is a carl and ellie, lady and tramp (seems to be rare), robin hood and maid, and yoda valentine. They aren't very cute in my opinion.
There are 5 - Robin hood and Maid Marion, Boo & Sulley(Kitty), Lady (no tramp), Yoda, and Carl & Ellie. I was selling all but Lady for 1k and have been told Lady is 30-40k. That may have inflated since they're no longer available. I think they're pretty cute Find me in game to see them if you want, I'm too lazy to mess with screenshot nonsense lol
