Turns out the 'rings of time' are not so mysterious, after all. They were revealed to simply be an old plastic six-pack ring found under a dock in L.A. by a drunk (Saw the special on the Discovery Channel last March). Also, the green dog seen by the drunk was actually only a styrofoam fast food container in the sand covered in green seaweed, so it is not worthy to take the place of the mudshark in your mythology. Hope that clears things up.
