Hey! Thanks very much for your reply.
I'm a noob when it comes to Cellular Automata, although I've actually just coded a working map generator using similar principles and could possibly modify that to make more organic creature-like shapes. However I loved your code as it incorporates shading and colours and the results are just fantastic.
Thank you for the offer, but don't worry about coding a save as separate parts button. I've saved some of the results that I liked and I will probably use a sprite editor to animate them manually. By the way, I'm only using this for a game that I'm making for me and some friends, I have no plans to release it or sell it, however if I should and I do end up using your code I will of course credit you :)
Thank you again for this, it's a work of art!
