Super Mario Bros. 2

This release of Super Mario Bros. 2 is completely different from its original Japanese counterpart, originating in the West and being in fact a version of Yume Kōjō: Dokidoki Panic with a different storyline and protagonists swapped for Mario and his friends.

One night Mario has a strange dream, where he opens a door to another world filled with even stranger creatures and lands than those in his last adventure against Bowser. Amazingly, the next day, Mario, Luigi, Toad, and the Princess stumble upon a cave, which leads to the world that was in Mario's dream.
