Now this is pretty creative! I'm still new to One Piece though. So Oda made the customized Jolly Rogers for each character and you just made animated versions?
When I first clicked on the link to this, the animation was slower than in the preview. I thought that might be because of all the other animated Jolly Rogers in the "More from" block on the right. Well, it seems to be at the right speed now, but my typing is lagging.
