Yume Koujou: Doki Doki Panic

The original SMB2 was much like the first, though it had major changes (such as the poison mushroom). Because of all these changes, it was considered to be too hard for Americans, and we instead received a modified version of a game known as Doki Doki Panic. The changes made were relatively small. First off, the four main characters were replaced with Mario, Luigi, Toad, and Princess. The 1-up mushrooms were just a picture of the current players head, and the ending bird-face that was on the wall of each level was a big mask. The original SMB2 was first released in America in an SNES game known as Super Mario All-Stars, though it was renamed Super Mario Bros.: The Lost Levels.
