4 More great action with the Straw Hat pirates!Kumadori | 08/11/2013 | See all Kumadori's reviews (11)This volume of One Piece sees the crew land on Drum Island in need of help for Nami, who has come down with illness. The episodes in this set provide many great moments not only from an action perspective but also from a character development perspective. We get to see the crew really bond over a common cause and in turn have a new addition join the fold. The new person in question is the one who graces the front cover, Tony Tony Chopper. We get to see his story and come to appreciate why he's such a unique and multi-talented individual. Overall if you've got this far with One Piece and are clamouring for more, you can't go wrong with Collection 4!
