Yume Kōjō: Doki Doki Panic (夢工場 ドキドキパニック, Yume Kōjō: Doki Doki Panikku, lit. "Dream Factory: Heart-Pounding Panic") is a Japan only game that is based on a family who plans to save two children. The game was later remade and brought to North America as Super Mario Bros. 2, which was rereleased later on in Japan as Super Mario USA.
