In the world of Super Mario RPG, you we're fortunate enough to have one of the seven Star Piece's. Keeping it close in your part of the world. However, eventually the main hero's Mario, Mallow, Geno, Bowser and Peach arrive, having caught wind of you owning the piece...and they're going to take it from you.

Mario: "Oh boy, that a creature has the Star Piece. Maybe we can take it peacefully for once?"
