The Wood Norns were developed by Frimlin for Creatures between 1996 and 1998. The sprites were modified originals based on those of the Horse Norns and the Purple Mountain Norns, while the genome was custom-built. Lis Morris created the adult and senior life stage male body data files, while Chris Double and Martha Brummett assisted in testing them. They occupy norn breed slot 8, clashing with Kathira's Dragon Norns, the Dwarf Norns, and all of Spirit's breeds.
