User blog comment:Angelwings21/Question about the re release of the original ghouls?/@comment-5059922-20150604165133

Based on what I've heard, there were some minor changes to their appearances. I think this may be because they wanted to update the quality of the dolls. You have the option of buying probably just one of them (but I don't see an option for Lagoona or Ghoulia online) or you can buy them all in a six-pack.
