Subcon

Subcon (originally Muu and sometimes called Sub-Con; also known as Mushroom Kingdom II in Super Smash Bros. Melee) is a peaceful dream world of the Subcons. In the Mario universe, Subcon is believed to be just a dream, though it may be a linked subconsciousness of the people of the Mushroom World.

''Super Mario Bros. 2
Subcon is the main setting of the game Super Mario Bros. 2, where the world was first available. Subcon was once a peaceful place, until it was taken over by the tyrannical frog king Wart and his army. He then enslaved the inhabitants of Subcon to be his soldiers. Wart captured the Subcon fairies, the protectors of the realm and imprisoned them so that they would not interfere with his evil plans. While he resides in the Castle of Subcon, Wart created monsters with the Nightmare Machine, and sent his army all around the dream world. While he fully succeed to take over the world, Wart became the king of Subcon himself.

From their confinement, the Subcons sent a message to the hero of the nearby Mushroom Kingdom, Mario, to come and deliver them from the dictator. At first Mario thought the message was just a dream, but the next day, while on a picnic with Luigi, Princess Toadstool, and Toad, he discovered a cave that led him to the very world he saw in his dream.

Mario and his friends instantly set out to free the fairies and defeat Wart to free Subcon from his reign. They battled their way through Wart's army, the 8 bits, and his generals: Birdo, Mouser, Clawgrip, Fryguy, and Tryclyde. In the end they faced the evil king himself, and were eventually able to defeat him and free the captive fairies. They then awakened to find themselves back in the Mushroom Kingdom.

Super Mario Advance
In Super Mario Advance, there were Yoshi Eggs scattered all around Subcon, which Mario and friends has to recuperate.

BS Super Mario USA
Subcon is again the main setting of the pseudo-sequel of Super Mario Bros. 2 for Satellaview, BS Super Mario USA. Sometime after the events of the invasion in Subcon, the world was peaceful at the time. Wart went into hiding, but suddenly returned to the dream world of Subcon and overthrew the world's king.

Finally, Mario, Luigi, Toad and Princess Toadstool were able to return save Subcon from Wart's reign while asleep. While they were opposed by the spells of Wart and his forces, they had a valuable ally in the King of Subcon. They fought the 8 bits, the leaders, defeating the evil king Wart several times in the same way in the prequel. By doing so, they saved Subcon, the inhabitants, its kingdom, the king, and the world is once again at peace.

Super Smash Bros. Melee
Subcon made its first Super Smash Bros. series appearance in Super Smash Bros. Melee. Subcon made its third appearance as a stage of the game called Mushroom Kingdom II and it is based on World 1-1 and 1-2 of Super Mario Bros. 2. Mushroom Kingdom II is the second Mushroom Kingdom stage in Super Smash Bros. Melee. It can be unlocked by collecting the Birdo or the Pidgit trophy. Unlike the first Mushroom Kingdom stage, Subcon has 8-bit graphics converted into 3D and 16-bit graphics that remain 2D. Strangely enough, this stage doesn't take place in the Mushroom Kingdom, despite the name.

Physical Features
Red plants stick out throughout Subcon, which, when pulled, will give the character an item (or occasionally, a Bob-omb). A lot of the region of Subcon is high in the sky; the "land" being clouds. The dream world has many moons at night as first seen in Super Mario All-Stars. Subcon also has many recurring landscapes, such as deserts, snowy lands, islands, mountains, grass plains and others. The only castle is Wart's castle, and no towns or cities is seen throughout the game. However, according to BS Super Mario USA, Subcon has a kingdom and a king. Wart's castle from World 7-2 is the king's castle, which was in the sky.

Subcon Kingdom
The Subcon Kingdom is the kingdom of the dream world especially where the Subcon King made lots of Gold Statues of Mario in BS Super Mario USA. It is the setting of BS Super Mario USA. The kingdom itself is ruled by the king, including the whole world. In Super Mario Bros. 2, the seventh world in the clouds of Subcon above the grass or the desert region is probably the whole region of the Subcon Kingdom itself. In BS Super Mario USA, it has shown that the kingdom confirmely had grassy, desert, and ice landscapes as well.

Currency


Subcon also uses Coins, though their design is different with a "I" mark on it instead of "1" from Mushroom World. Coins in this world are rather rare. Instead of being found floating in the air on Mushroom World, for unknown reasons, Coins could only be retrieved by using a Magic Potion to create a door near unpicked vegetables and lead to Subspace, where the Coins are found, but could not be found if the vegetables are already picked outside Subspace. Coins are mostly known to be used to earn prizes (1-ups) in a minigame after finishing a level.

Demographics
Subcon's population consists many species, as well as from Mushroom World (Subcon's original species began to reside on Mushroom World as well). Most prevalent are Subcons, Shy Guys, Bob-ombs, Ninji, Albatrosses, and Pokeys. The King of Subcon is human, there are very few humans living in Subcon as well. Species from the Real World, like the Whales and Snowmen, reside on Subcon's icy land.

Trivia

 * The name "Subcon" is short for "subconscious".
 * In Yume Kōjō: Doki Doki Panic, Subcon (then called "Muu") was in a storybook that the kids Piki and Poki get pulled in by Wart ("Mamu") and get locked in a cage. In fact, the reason Chapter 7 is only two pages is due to the fact that the original ending was accidentally destroyed. This detail is lost in the Mario version of the game's events.
 * In the Nintendo Adventure Book Dinosaur Dilemma, the text describes Wart as "the king of the Land of Nightmares", presumably referring to either Subcon or a similar realm.
