Mushroom Kingdom

The Mushroom Kingdom is the primary location of The Yoshi Show. It is ruled by Princess Peach and inhabited by every character in the series. Bowser often attacks the castle, but Mario ends up saving Princess Peach every time.

Government
The Mushroom Kingdom is a monarchy. Princess Peach acts as the head of the government, while her title as "Princess" raises arguments of what her presence in the government is. The Mushroom Chancellor remains in office for many years and gives advice to the kingdom's government and is the second in command after Princess Peach, who is first in command. As Chancellor, he takes over as the acting leader of the government if the ruler is gone for an extended period of time.

Demographic
Although the Mushroom Kingdom is primarily made up of Toads, many other ethnic groups have joined the Mushroom Kingdom in the past years. 66% of the Mushroom Kingdom is made of Toads, 19% of Koopas and 9% of Bob-ombs. Those are the majority, but around 2% are Shy Guys and/or Bandits, 2% are Yoshis, 1% are Bumpties, a small 1% are Piantas and the remaining 1% are humans and other small ethnic groups (making a total of 100).

Transportation
The main mode of transportation in the Mushroom Kingdom has been said to be through Warp Pipes. The range of these warp zones vary in length: some pipes merely travel a short distance (such as over and underground), while some pipes are linked to entirely different worlds. In Super Mario Bros. 3 Mario and Luigi were able to transport to different worlds using "warp whistles." Warp whistles have not appeared in any Mario game since, but a very similar warp whistle did appear in the first game of the Legend of Zelda series, it had the same general look, and even the tune played when the warp whistle is used is the same. New Super Mario Bros. introduced a new variation called warp cannons.

The Mario Kart series opened up the concept of automobiles and motorbikes (not just karts) and highways in the Mushroom Kingdom, so it is an unclear issue. Flight is possible, as many inhabitants of the kingdom are capable of flying. Some have the natural ability (Lakitu, Hoot, etc.) while Mario and Luigi would need flight-enabling power-ups or outside assistance such as a flying carpet. Aircraft of various sorts have also been seen in more recent games; the Koopas have a tendency to use flying ships, Isle Delfino was reached by the Toad Express (which landed at an offshore airport), and the blimp in Paper Mario: The Thousand-Year Door, which was used to travel to the Glitz Pit. Aquatic transportation is usually covered by swimming, but gondolas, submarines, and even cruise ships have been seen as well.

Technology
Technology has also been seen in various forms throughout the Mario games. In earlier games of the series, not much technology was seen, and this led people to believe that the Mushroom Kingdom still used antiquated niceties as evidenced by the many castles and old-fashioned houses that the mushroom people live in. However, starting with Super Mario Sunshine, modern technology has been seen in the series. as Peach and Mario fly to Isle Delfino on the Toad Express and watch a tourism video on a television. Modern electronics and infrastructure have been seen, as in Paper Mario: The Thousand Year Door, Mario has a handheld device analogous to a PDA that he can read e-mails on. In Mario and Luigi: Partners in Time, a time machine is also featured. Not to be overlooked are devices such as F.L.U.D.D. There is also the Game Boy Horror in Luigi's Mansion as well as lots of electricity throughout the mansion when you clear rooms in the mansion. In Mario Kart: Double Dash!! more modern technology such as automobiles and neon lights can be seen in some of the tracks (such as Mushroom City). Super Mario Galaxy has confused the matter even more, as the technology utilized by different characters in the series have surpassed even modern technology. For example, Bowser has access to a Koopa Clown Car and flying battleships, along with metal planets that have somehow utilized their own gravity fields. The overworld, appears to be designed far beyond present human technology, and through the overworld, the Toads were able to design flying aircraft in order to find stars and counter Bowser armada. There is though great technology invented by the one and only E.Gadd, check E.Gadd's inventions, he definitely changed the Mushroom Kingdom's technology to another level. Providing Luigi with a weapon that can kill what's already dead. The Poltergust 3000, and up.
