The Great Wiggy
Oh hear ye the names of the Greate Wiggi:
The Great Wiggy, The Great Squirrel, The Great One, The Universe, The Oldest Wiggy
The Basic Premises
It is impossible to move out of the The Great Squirrel's Tail unless you are lighter than fluff which is of course impossible. The fact that fluff is the lightest substance in existence and Wiggys are made from fluff (especially the tails) logically means that the Universe is the tail of a squirrel. All energy (photons, mass, forces, etc) are products of fluff interacting with fluff.
The Direction of the Universe
The Great Squirrel is moving due West, meaning hir tail is poiting due East, or possibly North (depending on the flick factor.)
The universe, being a tail, is sinusoidal in its movement, so it is not moving in a straight line from A to B but taking many excursions in semi circles. Thus further proof that the Universe is a squirrel.
The Universe is moving from East to West along an unknown path, sometimes called The Wiggy Trail.
