These four norns are all descended from one of Tue's modified genetic files.  When I first modified Tue's genetic file, it was to change which sprites were being used & I did not realize how slow Tue aged.  These four are all descended from that early version of the file, so they will age at a VERY slow rate.  Some of them are over 12 hours old & still have not turned into adults yet.

The sprites they use are - Pearl Mernorn legs, Neko ettin heads, guppy ettin tails & Bengals des Neiges V2 body & arms.
