Thanks for the help on that, but I guarantee I wouldn't have found it without your help, because even with your hints I only found it by accident - namely I was looking for something odd, even when I saw something odd it almost didn't register.
I'm not sure that this is "playing the game". I don't mind obscure clues, that's part of the fun. But when one's accidentally comes across the name before being able to see the creature is pushing the boundaries a little too far.
Anyway, thanks for your help everyone.
Now I'm off to hunt for Vinvella and Sibel who appear to have migrated to China - possibly together.
