How about this little cutie right here?
In the vast world of One Piece, there are characters you love, hate, love to hate, or just find kinda meh, there are some that you'd really rather not be stuck in a room with for one reason or another. But what if you had to be? Of the above options, who would you choose to spend your time with, and why?
There would be board games, cards, and two player video games in case you get bored, and food/water are available.

Personally, I'd go with Satori because I don't mind him, and think he's kind of fun.
I don't own it myself, but there are a couple on Yahoo Auctions Japan if you have a reliable proxy:
You can try ordering through FromJapan or ZenMarket if you aren't in Japan
They will charge a fee though and you'll have domestic and international shipping. Depends how much you want to pay.
Thank you for the links! I'll consider these, but don't know how much I'm willing to pay for shipping/fees at the moment. Going to keep my options open.
