The Mushroom Kingdom is a monarchical governed state ruled by the Toadstool Dynasty that which is almost always the main setting where SMG4's bloopers take place. There are many different species that reside in the kingdom including Toads (the majority), humans, Goombas, Koopas, SMG4's gang, and Teletubbies.


The Mushroom Kingdom is a country where most of the Mario games take place. The geography of the country varies, from green plains, jungles, deserts, snowy lands and volcanic areas.

The Toadstool family is the ruling dynasty over the citizens of the Mushroom Kingdom, with the current ruler being Peach Toadstool, the Princess of the kingdom, taking over the role from her unseen father, the Mushroom King. She resides at her official residence, which is her castle located north of the capital. While the monarch is the head of state of the kingdom, most of the power in the country is handled by the President of the Mushroom Kingdom, who is the head of government, as seen in Super Mario 64 Bloopers: President Toad Washington. This is unusual since the head of government in a monarchial state is usually called the Prime Minister.

The capital of the kingdom is called Mushroom City. Meanwhile, the official currency in the kingdom uses Mushroom coins. All vehicles in the kingdom drive on the right side on the road, with the steering wheel on each car on the left side. However, it is shown in some videos that vehicles would drive on the left side of the road (much like its seen in countries such as in Australia, Britain, and Japan), probably due to the series being made in Australia, where cars drive on the left side. Still, steering wheels are located on the left.

In its history, the Mushroom Kingdom may have been under foreign powers and was ruled as a colony by a certain European country (since most colonies were ruled by European countries at that time), which explains the appearance of the Declaration of Independence in the Mushroom City Natural History Museum in The Mario Channel: MARIOBUSTERS. After the kingdom gained independence, the Toadstool family then took over power from their colonizers.


Throughout the series' timeline, the kingdom has been seen in much peril, such as being invaded by bootleg supremacists, two T-Pose pandemics, and pro-anime riots. Additionally, there was a timeline set 500 years in the future where sentient Weegee Dolls conquered the kingdom, which fortunately was undone by Luigi, Fishy Boopkins, Shroomy, and Mario's descendant New Super Duper Mario Plus Ultra.

In SMG4: Mario Runs Out Of Toilet Paper, Satan (disguised as the Papa John food mascot) decides to destroy the world and kill everyone just for the fun of it. To do so, he causes a toilet paper shortage in the kingdom. As its citizens depended on the paper, a panic-mass buying of toilet paper began, but thanks to SMG4's gang, the plot ended.

Even with those catastrophes, the kingdom is able to rebuild every single time, probably due to its strong economy.

  • The Mushroom Kingdom's population is around 15 million people, since, at the beginning of SMG4: Mario and The Diss Track, the counter of Bob's fans is around that number, while Saiko said "everyone in the Mushroom Kingdom are already fans of him", although she could just be exaggerating.
  • In the Nintendo counterpart, Bowser rules the Koopa Kingdom, but in SMG4's universe, he and all Koopas seem to live along with the residents of the Mushroom Kingdom.
  • The Mushroom Kingdom has been through numerous apocalyptic events and attacks; too many to even count, but notable events include:
  • The Mushroom Kingdom may possibly be located at Europe and the Mediterranean Sea, according to SMG4: A Day In The Life Of Everyone.
  • The Mushroom Kingdom may have been under foreign powers and was ruled by a colony as a certain European country, which explains the appearance of the Declaration of Independence in The Mario Channel: MARIOBUSTERS.
  • The Mushroom Kingdom could be a constitutional monarchy, as Tari has stated the word "President". But it could possibly be a former constitutional monarchy before converting into an absolute monarchy.
