Animating the snake

So i knew i had to do some animation for my file even though it really isnt my thing at all, however it had to be done. I had previously done a small amount of animation with the tortoise just a short walk cyccyle as a test, unfortunately the tortoise got dropped. Anyway we had a snake already rigged but not texture, therefore i needed to texture it then animate it for a scene in the film. The texturing went well but the UV'ing for it whoever had done it wasent great, but its so small thats its hard to tell anyway. I originally animted it moving along the floor and rearing up. Unfortunately when i imported it into the environment and tried to scale it down it messed up and corrupted. Therefore i had to unbind it and re-rig it to size. It took some time but i managed to get it done and animted in the scene. Heres the test animation for the original movement.
