I remember this from the old forum and basically you look at the ID of the creatures and post it if it's pretty interesting. Usually you go for legibility. For instance I have a seadrake I'm training for alchemy with the ID "ghyst", which I find interesting as it's one letter off from ghost. Also apparently "Ghyst" is in fact a surname.
Well, pickings are slim this early in the game, but I have an Inkwell dragon that has 'hemp' in the ID. Which is slightly interesting, as I believe they used to make paper from hemp. https://mirrorwood.com/view/hempJ
