Lubufu is an old fisherman found near the Brimhaven player owned house portal, marked with a icon. He holds the secret to catching karambwan and is the source of the supply for the nearby bar The Shrimp and Parrot.
During Tai Bwo Wannai Trio, he teaches the player how to catch karambwan in secrecy after offering them an apprenticeship. However, the player ultimately betrays him by teaching Tiadeche how to catch karambwan, in order to bring him back to the village. If spoken to after the quest, he scorns the player for their betrayal.
