Flatherfowl and Fowlflathery Dimensions

The twin dimensions Flatherfowl and Fowlflathery (also known as D-1A and D-1B) are a rare case even amongst twin dimensions. Branching due to a small difference for only a very short time led to the ultimate annihilation of both. As such, while theoretically they could have become different enough dimensions due to the Butterfly Effect, their ending caused their spacetime continuum to be almost entirely identical.

An interesting result of this was that when large populations of people fled both dimensions, they were so similar each of them merged into one person.

Notable personalities of these dimensions include but aren't limited to:
 * Supreme Duckz Commander
 * Super Duck
 * Duckz Vader
 * Alo Nosh
 * To add stuff
