If the name isn't pokemon, which is highly likely, Jojovial might be referring to the fact that it looks like a pokemon!
Which it kind of does. There is I think a pokemon version of an axolotl called mudkip, but they've made it look a little different to our axies.
All things aside, Jojovial, you have fantastic pics! I wish you had more time to post pics - I always look over these pics again and again b/c they're so interesting!
