So I was looking at ideas for my tournament battle, right, and it occurred to me that Iron Ball doesn't double the holder's weight! Why is there no item that doubles the holder's weight? That's outrageous! And especially so considering that there exists an in-game item called Float Stone that halves the holder's weight! So I was like, "Float Stone? Where's my goddamn Sink Stone, huh? I want my Sink Stone!" But then I realized that a Sink Stone is really just a plain old Stone, if you think about it. So I propose that we add an item called Stone to the game. It would go with the other stones.
