Imagine, if you will, a story about a downtrodden Italian plumber name Mario, recently emigrated from his Mediterranean country to a land of opportunity and promise: a place called the Mushroom Kingdom. Along with his (curiously thinner and taller) twin brother, Luigi, Mario arrives and soon finds the love of his life, Peach. She's got identity issues and seems to be a magnet for trouble.
Even though she's royalty, her family is suspiciously out of the picture, so the two spend loads of time together and hit it off. They get into 'shrooms and get mixed up in those pipes -- before they know it, they're in with all the wrong people and Peach pawns everything but the pink dress off her back just to get a fix.
