Mushroom Kingdom

The Mushroom Kingdom is where Mario and Luigi rap in Epic Rap Battles of History 18.

Information
The Mushroom Kingdom is the world where most of Mario's adventures take place. The Kingdom has countless of environments and terrains, which mostly serve as 'worlds' for Mario to travel through or they serve as a theme for a level in a multiplayer game, like Mario Kart. It is a monarchy, ruled by Princess Peach. The capitol is Toads Town. While the ruler is human, the biggest part of the population exists out of Toads, and many other species imigrated to the kingdom through the years, including Yoshi's. Mario, Luigi, Peach, and a few others appear to be the only humans in the kingdom. The kingdom is often tormented by the Koopa Kingdom, but it's unsure if the Koopa Kingdom is a seperate kingdom or another location in the Mushroom Kingdom.

Trivia
The location in ERB appears to be the most standard environment in the Mushroom Kingdom: Green plains and hills.
