User blog:Chartic/Caribou for Shichibukai?

I was thinking recently about Caribou's name, and I was curious as to how many characters in One Piece have animal names. I cannot think of any other than the original Shichibukai... maybe my memory is lapsing. But maybe its a hint that Caribou might become a Shichibukai in the future, he does have a large bounty already. I know its a stretch though, there aren't any other things pointing to it, that I can think of.
