There has been a howl and roar added (no sound as of yet, and I'm not sure if there will be, just imagine the racket when every wolf starts howling, which they will XD) There is also a lick, but it is not much, just the tongue sticking out, and then you have to move the head.
I like the serval idea, although, the brindle could be an issue. How would it work? Because brindle is a very hard design to get right, I have never been able to do a brindle design that looks ANYTHING like a brindle design XD
