Barbaros' Body Parts are the central goal of the game, and the central goal of almost every level. A long time ago, Barbaros did evil stuff, so Wiki cursed him, transforming him into seventeen pieces of treasure.
Then, a long time passed, and Wiki has forgotten what he did to Barbaros. With the help of Zack, they came along to free the old pirate and promised to restore him, at the cost of Zack earning Barbaros' legendary ship.
As their adventure progresses, Zack and Wiki used to have all the real body parts during the time Barbaros was with them, but after Barbaros betrayed them and escaped in the ending, the body parts in the locker are now a replica of the original, which the two claim to get the original versions back and not letting them get away.
Barbaros's Head was the first part of Barbaros that Zack and Wiki found at A Journey Begins, which was also what started their great adventure. He offers to take Zack to Treasure Island and give him his legendary ship, if Zack finds all of the Body Parts.
