probably the worst way to make a plane, it doesn't work right, mainly because it's not balanced correctly also because you used the geometry controller rather than a realistic way of operating it.
hey this is an awesome scene but i think this is more of a worm that a snake, considering you can cut this creature in half and it'd just be 2 slightly smaller versions of itself
BTW if you make the first segment a killer and make it run into a long wall of small particles fixated to the background, it makes itself a little tunnel
