One of the folks I met on a furry RPG server was Desoto Olcan, a Jelly Werewolf with a rather unique tail maw that produced jelly of interesting effects. He took an immediately like and then loving of my character Murana. So much so that he approached me and offered to be her mate outside of the Zootopia story canon that I was writing and establishing. It didn't last long as a RP relationship, but we both got some great art out of it, this one being one of my favorites.
