Barnacle Bill was a Sim who once lived in Barnacle Bay. He drowned as an elder and rests in the Dead Men Tell No Tales Cemetery. His name "Barnacle" might indicate that the town Barnacle Bay was named after him. Adding to this theory is the description of the house Oceanaire Cottage, which states that "Barnacle Bill himself used to live on this land" and that he now resides in the cemetery. He has a moss green skin and grey hair like every other deceased Sim of Barnacle Bay.
