Super Mario Bros. 2 is known as Super Mario USA in Japan. It is a remake of Dream Factory: Doki Doki Panic (夢工場 ドキドキパニック, Yume Kōjō: Doki Doki Panic), in which the characters from the Fuji Television "Dream Factory '87" event are replaced with characters from the Super Mario series.



Mario and his friends were summoned during their sleep to help in Subcon, the kingdom of dreams. The evil Wart and his minions took over the kingdom and captured the Subcons, the fairy-like creatures that inhabit the dream world.

Thus, Mario, Luigi, Toad, and Princess Toadstool had to travel across seven worlds, defeated Wart's minions, and ultimately defeated Wart himself.

Unfortunately, it wasn't easy as Wart was impervious to physical damage. However, he was able to be hurt if he ingested vegetables. Luckily the Subcon Dream Machine, of which Wart took control, alternated between creating monsters and creating vegetables.

Ingesting four vegetables defeated Wart, freeing the Subcons from the vase in which they were imprisoned, thus finally making Subcon free from the terror of Wart and his cronies.


In 1987, Fuji Television created a special event titled "Dream Factory '87". Fujisankei Communications Group, the company that owns Fuji Television, previously worked with Nintendo in 1986 to create All Night Nippon Super Mario Bros., a version of Super Mario Bros. that contained celebrities, logos, and other objects related to the All Night Nippon radio program. Fuji Television commissioned Nintendo to create a game based on characters from their "Dream Factory '87" event.

Kensuke Tanabe and the team at Nintendo R&D4 already had a Mario platforming prototype. The prototype originally had vertical scrolling gameplay and emphasized throwing blocks. Shigeru Miyamoto suggested to use horizontal scrolling gameplay. When the prototype was expanded into a full game it contained Mario elements, such as the POW block from Mario Bros. and the Starman from Super Mario Bros.

However, the original Doki Doki Panic contained characters from "Dream Factory '87. The story revolves around a storybook. Twins Poki and Piki were fighting over the last page of the book, and the evil Mamu pulled them into the book. Their family has to venture into the storybook themselves to save them. The brother, Imajin, was average in all areas. Mama could jump high and float for a bit. Lina, Imajin's girlfriend, could hover, but she lacked speed and strength. Papa was the strongest and fastest, but he couldn't jump very high.

Nintendo decided not to bring Super Mario Bros. 2 to North America, as they felt that it was too similar to Super Mario Bros. and would be too hard for North American gamers. Instead, Nintendo of America localized Doki Doki Panic so that it would be a Super Mario game. This game was released in 1988 in North America, Europe and Australia as Super Mario Bros. 2. It was localized in Japan as Super Mario USA in 1992. Then, when the original Super Mario Bros. 2 was released outside of Japan in 1993, it was titled The Lost Levels to differentiate it from the game they received as Super Mario Bros. 2.
