Admit it: we've all had day dream about how cool it would be to hang out with at least ONE member of the Strawhats or someone else from One Piece.
Including the above options, what would you want to do while in company of the Straw Hats OR with anyone else from One Piece.
Personally, I'd want to play Brawl with Luffy, Usopp, and Chopper.
That and go on a heist with Nami.
EDIT: I'd also love to try both Sanji's cooking and takoyaki from Hatchi and Caimie.
