Bandai Networks has released "Pirates Dodgeball" game through "One Piece Mobile Jack," a site for iMode game release site.
Characters from "One Piece" will appear in this Pirates Dodgeball. Basic rules are same as normal dodgeballs, but each character will have a special technique. It's 315 yen to use the site.
I don't think you can play it from outside of Japan, but it's still cool to know.
