S10E343 · His Name is Moria! The Great Shadow-Seizing Pirate's Trap!

After beating the zombies, the Straw Hats learn that one of the Shichibukai, Gecko Moria, has been stealing people's shadows and using them to revive zombies. After they leave, Absalom rallies the zombies together for the Night Attack, while the ghosts from before return to their master, a Gothic Lolita-style Ghost Princess Perona. Gecko Moria himself, a massive, giant-like man, is awoken. The Straw Hats come to the realization that Thriller Bark is not an island, but rather, a massive ship!
