Austrailia

Austrailia (sometimes misspelled as "Australia") is a continent of great power and awesome beach spots. It held about 50,000 or so Humans and about 100,000 Kangaroos including the ever famous King Kangaroo. However, it was destroyed by Weegee after their refusal to join UnYoshiWorld in the Videogame Wars.
In the future, Weegee pleeded guilty and gave Earth New Austrailia's location.
