Vincent Skullfinder is a pre-made deceased Sim who died of old age. He is buried in Pleasant Rest Graveyard in Sunset Valley. He shares his name with a character from MySims. It is possible they are the same man, as they look alike. In MySims, he acts mean and serious, and yet his favorite color is hot pink. This is probably an Easter egg made by developers.
There is a possibility that he is related to the deceased Victoria Skullfinder from Barnacle Bay, since they share their surname, initials and taste for Key Lime Pie. Strangely, Vincent has only one trait, which is Artistic, similar to Kitty Landgraab and Jennie Clavell.
