Barnacle Boy

Barnacle Boy is depicted as being the undercredited and underappreciated younger sidekick of Mermaid Man. Grumpy and slightly ill-tempered, Barnacle Boy is notable for his brooding, moody disposition and exasperation with his partner's absentminded behavior as a result of old age, and even into his golden years, Barnacle Boy is still treated in a juvenile fashion, coddled in an infantile way. In his later years, he slightly resembles Squidward Tentacles. He has largely maintained his nondescript slender physique over time. In the video game SpongeBob SquarePants: Battle for Bikini Bottom, Barnacle Boy has a son, a daughter-in-law, and four grandchildren which he notes to be his son's "four screaming children".
