A mysterious floating treasure tempts Luffy and his Straw Hat crew into the treacherous waters of the Florian Triangle. Before they know it, they've sailed into the maw of Thriller Bark, an extremely creepy zone populated by ghouls and ghosts and an awful lot of zombies. Soon the crew has lost their shadows to a very nasty enemy-Gecko Moria, one of the seven warlords of the sea. Will Moria make zombies of the Straw Hat crew?!
