Just a small champion idea

I got a tiny idea for a champion that could be a snake/worm or something and probably a jungler. Well, his main ability would be that he collects or eats objects on the map and grows up in lenght. He makes impassable wall with his body by moving and can only be harmed when his head is hit.
