Four years after the release of Super Mario World, the Super Mario Bros series continued with his most original episode.

The game takes place many years before the original Super Mario Bros (NES), when Mario and Luigi were still babies. Since a certain Bowser heard that these 2 kids were going to take care of his princess kidnapping business in the future, he sent Kamek a sorcerer to kidnap them. He was able to take Luigi, but Mario fell down on Yoshi's Island.

Graphically, this game is amazing if you consider that it was published on SNES, with very children drawings like graphics. You mostly control Yoshi instead of Mario, making the gameplay really different of the other Mario games.
