The Straw Hats' entrance to the Grand Line is marked by a heartbreaking revelation from the lighthouse keeper, Crocus: the giant whale, Laboon, has spent fifty years waiting for his long-dead crew, the Rumbar Pirates. Refusing to let the whale's loyalty end in self-destruction against the Red Line, Luffy takes a characteristically direct approach. He challenges Laboon to a duel, and after declaring a draw, paints his own Jolly Roger over the whale's scars, forging a new promise to return for a rematch. This profound act gives Laboon a new reason to live and solidifies the crew's first bond in the treacherous sea.
