Mario and Luigi: Across the Dimensions It would be a bit ironic, but a really cool game. So here is the story: As always, Peach invites Mario to the castle for cake, half-expecting Bowser to interrupt everything. But that's not what they see. They see this: _______ // O O \\ // | | \\ || | | || (I'd give a picture, but they are a pain in the butt to deal with.) In case you aren't aware, this is a Hell Valley Sky Tree. (Yes, I made a wiki.) He says: "What's wrong? Don't you recognize me? How about we have a blast from the past? Mwa ha ha ha ha ha ha!" Then he sends them back in time to every past Mario game, in the inaccessible areas of many of the levels, in which Mario has to collect a power star. After the first level in Super Mario Bros., the star takes him to Rosalina, who sends them to "an old friend" who supposedly knows about this. When the Comet Observatory arrives at the destination, they hear the last sound anyone would EVER expect to hear. "Waluigi's Number One!" Maybe you will stop reading this right now. Shame on you. But if you don't, Waluigi shares his backstory: He came from a dark mirror universe with his buddy Wario through a mysterious pipe. With Waluigi's expertise (and frequent "Wah!"s), they track down power stars in every game.
