From Creatures Wikia
The Opera Ettins are a breed for Creatures 2 and occupy Ettin breed slot F and have a modified Golden Desert Norn genome. This breed was originally planned and started to be created by NornenMeister but while going into retirement he decided to cancel the project. (See some pictures on his website). So Alien finished this breed in the frame of her Pimp my Breed action with a brand new sprite concept and with the Original genetic files and sound files from NornenMeister.
