This rocks, here's my Idea
Hi Yoshi-1up, movie is great.
My idea is, Mario had told Princess Daisy that Luigi has a crush on Kammy Kooper (LOL). Daisy then wanted a chat with Luigi, she told him it was over. Luigi went overboard, Kicked a few castle tables over smashed a window or to and stormed out to get mario....
Hows that, I think it's ok, how about you?
