The family tree of the Barnacle Family appeared in Cap'n Buck's Monstrous Biography, written by Ruby Scribblez. There are only 29 family members shown, but the Barnacle family is said to have 8002 members, although nobody ever bothered to count. All of the family members' names start with the letter "B". They live(d) together on a rock located somewhere in Potion Ocean, 'near' Monstro City. As Buck got separated from his family during a storm, the state of the rest of the bearded barnacles is unknown.
