Old Super Mario Bros.: Super Toad Bros. is a fictionous game. It takes place in a time period where Bowser is dead and Bowser Jr. rules dark land. Since Mario and Luigi are too old to save the princess, some toads have to. Bowser Jr. now has his own son: Bowser III. The Koopalings are now adults and they now have kids. They are now too big to be defeated by stomping on their heads three times, so they now need to be defeated by a bridge over lava.
