hey i have seen this parts of a video a few times on youtube. It is with zoro fighting a giant monster i think it is a lobster. There are a lot off swords and weapons scattered about. I think he is fighting it with rusty swords if that helps. The parts of the fight I saw looked really cool could someone please tell me where this is from. Because i know it does not take place in movies 1 through 6 or in the manga (duh).
