From Creatures Wikia
Creatures 2 breeders were invited to download norns from a starting set (translation), to breed them together, and then to submit the resulting norns, a selection of which were offered up for voting (there were also a few left over - translation)
Overall, 353 votes were cast - the number represents the fact that you could vote for more than one norn. The winner (translation) was Chris (by Diana), with 47 votes. He was a mixture of Bird, Pegasus, Kanga and Stella genes.
