This small animation was made with my T4 Snake rig. Very simple as there were no limbs and the hardest part being I just needed got make sure the tail properly followed the body. I will say, this being my first time rigging and animating a character with no limbs, I would have done so differently. I put the COG right in the middle of the snake tail, treating the back half like a tail and the front portion to the head, as a spine. Looking back, perhaps the best way to rig this so it is as animation friendly as possible would be to make the COG be at the base of the head, followed by the entire body being the tail. I will just have to play around and see if I can find rigs of similar nature to study.
