From Creatures Wikia
Reindeer Norns are brown micro norns with black hair, hands, feet and tail. Like their name suggests they have antlers. Babies have silver patches on their bodies, which vanish when they reach youth (aka when they're able to breed). At that same time, males will also get a glowing red nose. They were made by Trix and occupy Norn Breed Slot R. You can download them at the Universe of Ettins.
