Thirteen Mushroom Colonies

The Thirteen Mushroom Colonies were a country ruled by King Koopa and the Koopa Pack. General George Washingtoad was fighting a war against Redcoat Koopa, during the events of The Koopas Are Coming! The Koopas Are Coming!. With the help of Mario, Luigi, Toad, and Princess Peach, Washingtoad and his army defeat Redcoat Koopa, and build their own country, which Mario and Luigi are official "uncles" of.

The land is a spoof on the original thirteen colonies that became the United States of America.
