Episode Synopsis
Brook recalls his past, when the whale Laboon started following his pirate ship and befriended the crew. When the crew headed toward the Grand Line, they had no choice but to leave Laboon behind because the danger the sea would present to a young whale like him, but Laboon followed them over Reverse Mountain, anyway. Brook and his captain convince Laboon to stay behind, promising that after they traveled through the entire Grand Line and he grew strong enough to follow them, they would come back and bring him on their adventures. They were unable to fulfill the promise, though.
Series Overview
Years ago, the fearsome Pirate King, Gol D. Roger was executed leaving a huge pile of treasure and the famous "One Piece" behind. Whoever claims the "One Piece" will be named the new King of the Pirates.
Monkey D. Luffy, a boy who consumed a "Devil Fruit," decides to follow in the footsteps of his idol, the pirate Shanks, and find the One Piece. It helps, of course, that his body has the properties of rubber and that he's surrounded by a bevy of skilled fighters and thieves to help him along the way.
Luffy will do anything to get the One Piece and become King of the Pirates!
