The Zodiac Norns were created by Mummy in November 2001. They have an amphibious genome. Occupying Ettin slot O, they are available from the Zodiac Norn web page at Mummy's Creatures in normal and coloured variants. In August 2005 they recieved an update by Mummy. The sprites got brighter in colour and little stars appeared on the ears. You can see the updated sprites below.
