Throughout the course of the game, Mario visits many diverse worlds, with abstract and unique obstacles in each one. Mario figures out that Bowser is behind the plot, and that he needs to collect the castle's missing Power Stars in order to rescue the Princess. Upon entering the castle, Mario realizes that Peach and her Toad servants have gone missing. Mario then heads to her castle, but he notices that nobody is there. Mario receives a letter from Princess Peach, who has seemingly baked a cake for Mario.
He also sports his iconic hat, which has been stamped with the letter 'M' in his namesake. He wears a red long-sleeved shirt, blue overalls with yellow buttons, white gloves, and brown shoes. His head hair is short and clean, and is of a medium brown shade. His most recognizable feature is his black bushy mustache, which sports a unique shape that contrasts the stereotypical Italian mustache. He has curvy black eyebrows, wide blue eyes, and a large nose.
Mario is a short, rounded man of Italian descent.
