Uhhh, just because more than one fansite describes it does by no means make it true. For example, I could make a fansite and say Luigi is in Super Mario 64 on it. I could say Bowser was really a woman. I could say Mario really only wants to save Peach because she has a lot of yogurt. But that doesn't mean any of it is true. If it's not in a game, it's not considered canon (though one may argue the cartoons are canon as well, but even then I highly doubt this was ever in a cartoon either) and the King of the Mushroom Kingdom has yet to make a video game apeareance. For another example, I truly do believe that Mario and Luigi's parents didn't send them to Brooklyn, but it was probably Toadsworth's idea. The Shroobs must have gotten them and the Baby Mario Bros. were homeless. But I can't march around saying it's a fact, because it's just an idea of mine that seems logical.
