One Piece is a Japanese manga series written and illustrated by Eiichiro Oda. It follows the story of a boy Monkey D. Luffy, who ate a devil fruit that transformed his body into rubber. Here starts his journey to be the next pirate king in search of a treasure named One Piece.
One Piece is all about different adventures and how all the characters played along very well and the bond shared by them in the manga series. We have talked about Luffy, Zoro, Sanji, and many different bonds that have been displayed in the manga series. Let's have a look at what type of bond Brook and Laboon share.

Brook and Laboon’s Bond Explained
Laboon is a whale that was found by Straw Hat pirates as soon as they entered the Grand Line. He is a native to West Blue and is classified as a Type A creature. It is seen that Laboon met Rumber Pirates after being lost and separated by his pod. After a while, they noticed how sad Laboon really was and they cheered him up by singing.
As a result, Laboon continued to follow brook and the whole crew was attached to him as he was a whale as well as very cute. Eventually, while feeding him, Brook named him Laboon. Here we see that he was very attached to him and also used to feed him daily.
Laboon was accepted as a Crew member by Brook first and then everyone agreed. Even though Laboon was the crew member now, the Pirates still decided to leave them and go to the Grand Line.

They didn't want to take Laboon with him as he was still a baby. Laboon was promised by Brook and all the members that they will meet after 2-3 years. Laboon even followed them to the Grand Line, but after repairing their ship, the crew finally bid him a farewell and promised him again that they will meet real soon.
When did Laboon meet Straw Hat Pirates?
In episode 62 of the manga, we saw that Laboon was found by Straw Pirates as Laboon was waiting for Rumbar Pirates and Brook when they first entered the Grand line. We see that in the manga Luffy gave Laboon hope before leaving the Grand line that he will surely come back.
Luffy also painted a Straw Hat Jolly Roger on Laboon’s head, commenting that the insignia would wash if Laboon hit Reverse Mountain further. After this Straw Hats and Laboon parted ways as the crew departed in good spirits from the Grand line.
