Lubufu is an old fisherman who doesn't like young whippersnappers. He can be found on the southern coast of Brimhaven, marked with a icon. He is the son of Kedoaba, brother of Kedenda and second cousin twice removed of Ibeli.
He plays a small role in the Tai Bwo Wannai Trio quest. He has a monopoly on the karambwan trade, as he is the only fisherman in Karamja who is capable of catching them. During the quest, the player manages to convince him to train them as their apprentice, and they then use the information he taught them to teach Tiadeche. This ends his monopoly over the karambwan trade. Attempting to speak with him after the quest results in him yelling at them for ruining his business.
During the Summer Beach Party, a Sandy Clue Scroll will sometimes direct the player to him.

It was mentioned by Mod Ash and Mod Mark on a livestream that Lubufu has a hidden dialogue that may be triggered when a player with level 9 constitution talks to him.
