Super Mario World 3: Revenge of Bowser
Mario and Luigi were in the middle of a relaxing vacation when they received word that Bowser had kidnapped not only Peach, but Toadette and Toadsworth as well! Toad had somehow escaped the attack and is able to help Mario and Luigi on their journey. Bowser was last seen in Koopa Heights, so our friends will head that way in hopes of rescuing the captives.
