Boy. So maneh things. But up front, don't have something under a paragraph long, and don't type it in the reply box. Look through it, and read the stickies before posting anything
Secondly off, use description. What do Peach, Mario, and Luigi look like? What are they talking about? Where are they? (The mushroom kindgdom is like a country- it's like saying that they were somewhere in the U.S., and climate affects alot. If you're in the Sahharah Dessert, or if you're in Alaska.) What does Bowser look like? Why were they watching the news? And put some dialouge in there, as well. I'd go on, but it's too shameful.
Thirdly, what kind of story is this? I mean really, you don't reavel the whole plot in less than a paragraph.
Fourthly, I all but know that you'll ignore this/Reply back with 'witty' comments. Don't. Take my advise, and accept that your story is crap. There are much harsher reivewers than I that will do much worse than I can or will ever type. So condsider yourself luck that you didn't get them.
