Hey, guys. I'm just wondering how we concluded that there's a Mushroom Planet separate from Earth? I haven't heard or seen anything that clinches it... except for the fact that the Mushroom Kingdom doesn't exist in real life. That really shouldn't be proof, though, since characters, etc. from true fiction don't exist either... anyway, I entertain the Wiki's theory and my own: the Mushroom World, as I refer to it as, is past a dementional barrier crossed by Warp Pipes. But, as you could guess, there's nothing much to back that up either. Let me know!
