From Creatures Wikia
The Snow Norns are the first breed that Amanora created for Creatures 1. They developed from the Banana Norns, to which she added the ears and the hair of the Desert Norns from Creatures 2. Little boys and girls are mostly white and differ only by blue and yellow orange stripes at their ears, arms, legs and tail. Due to this colouration, deviations in the children's pigments can be recognised easily, similar to the Albian Gray Norns. The stripes do not show up until later life stages, and in the aged stage they lose their coloured stripes again. They have the Survivor Genome of Ali, so they should be able to survive in Albia.
