Super Mario Bros. 2

Super Mario Bros. 2 (known as Super Mario USA in Japan) is a game based on Doki Doki Panic (which Shigeru Miyamoto designed) that was released in the USA instead of the Japanese version (known as Super Mario Bros.: The Lost Levels in the USA).

Super Mario Bros. 2 was released on the Nintendo Entertainment System in 1988 and the game is set in the dream world Subcom. Nintendo used this to explain why none of the game's enemies had featured in the first game. However, some (like Birdo and Shy Guy) have appeared in later Mario games.
