Agnes Seabottom is a mysterious young lady who lives alone in Barnacle Bay. Some players tend to think of her as parody of Agnes Crumplebottom, although she does not have a deceased husband. This is even mentioned in her bio. She has some similarities with Agnes Crumplebottom, including the "-bottom" name, her Loner trait, her love for Classical music, her pale skin and blonde hair. She has a noticeably small and fuller house despite her bio.
Her hair is blonde yet her eyebrows are brown, implying that she may have dyed her hair. Agnes is friends with Flora Annan, Laurel Lai, Josephine Coastal and Jasmeen Hassen, dislikes Thomas Quill and her ex-boyfriend, Moe Pesce. She is romantically interested in Dave Piece.
