Came across this in Jojohot, Chinese scanlation: http://pickup.filesbak.com/jojohotdxb2005/…rqf/page_01.htm
I've never seen this before. It's like a special chapter in Jump which consists of 4-koma comics with One Piece as central, but characters from other Jump series appear too. Hikaru no Go characters dress up as Strawhat Pirates, the Deimon Devilbats are a pirate crew (imagine Hiruma as a pirate captain gulp), people from Bleach, Bobobo, Ichigo 100%, Mr Fullswing and also Yugi, Naruto, Echizen. I think this isn't new because the title page uses an illustration from Skypiea time.
Is there any Chinese speaker here kind enough to give a summary? :)
