Mushroom Kingdom

The Mushroom Kingdom was the location where the Mario Brothers, Mario and Luigi, rapped in Mario Bros vs Wright Bros. It also briefly appeared in Nice Peter vs EpicLLOYD.

Information on the Location
The Mushroom Kingdom is the location where most of Mario's adventures take place. The Kingdom has countless different environments and terrains, which mostly serve as worlds for Mario to travel through or they serve as a theme for a level in a multi-player game, like Mario Kart. It's known in-game as one of the largest kingdoms in the world, but exactly how expansive is unknown. It's known that it overviews several different islands, countries, and continents, however.

It is a monarchy, ruled by Princess Peach. The capital is Toad Town, located just south of the Mushroom Castle where she resides. While the ruler is human, the biggest part of the population exists out of Toads (although, it is speculated that Princess Peach is part-Toad, given she has a Toad grandmother in Super Mario RPG: Legend of the Seven Stars), and many other species immigrated to the kingdom through the years, including Yoshis.

Mario, Luigi, Peach, and some 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 separate kingdom or another location in the Mushroom Kingdom. It's known that leader of the kingdom, Bowser, has taken residence in another land known as Darkland during Super Mario Bros. 3, and as each land in it is known to be ruled by someone other than Peach, it's possible this is where he resides.

Appearance in the Rap Battle
This is the location where Mario Brothers rapped. Another version of the location with only a blue background and one cloud appeared behind them during their cameo at the end of Nice Peter vs EpicLLOYD, when the ERB team was showing hints for Season 2 rappers.

This location appears to be the most standard environment in the Mushroom Kingdom: green plains, hills, and pipes. It uses sprites taken from earlier games, specifically the clouds being taken from Super Mario Bros., some having added eyes, and the blue and orange rectangular platforms being taken from Super Mario Bros. 3. There are also 3D pipes, which Mario and Luigi jump out of from time to time during the battle.
