Gill Norns are a completely water-bound breed in both Creatures 2 and C3/DS.
- The Creatures 2 version was created by Lis Morris and is accessible by visiting an archive of her website The Palace of the Evil Shee.
- Creatures 3/DS Gill Norns were created by Slaiterbait and are much like the Creatures 2 Gill Norns, fairly normal except they can only breathe water. They are available at The Lost Archives.
- Another type of Creatures 3/DS Gill Norns were created by ylukyun and released during the CCSF 2010. They are available at Engineering. These use Desert Norn sprites.
