These are the beta releases of the breeds for CA2DS. Although they do work, they need to be shrunk and might need a new genome (at present they use the default CA genome, incorrectly classified as Chichis). At the moment they need a special agent that comes with them injected, or they will crash the game.
They could be downloaded at Dementopia, but are now archived on Dropbox.com. Norngirl made several additional fixes for these breeds which are available at her site, Norngirl's temporary Storage place - Norngirls Creature stuff!.
