One Piece Omnibus Edition manga volume 12 includes volumes 34-36 and features story and art by Eiichiro Oda.

Against all odds, Luffy and his Straw Hat crew make landfall on Water Seven, a wacky maritime wonderland where the world's best (and worst) shipwrights gather. When the pirates learn that their trusty vessel, the "Merry Go," has sustained irreparable damage, the decision about what to do next rends the crew apart! In the meantime, mysterious archaeologist Nico Robin's dark past as a double agent is catching up with her, and the Franky family - a nasty clan of ship-scrapping bounty hunters - seem bent on the Straw Hats' destruction!

One Piece Omnibus 12 collects volumes 34-36 in omnibus format.
