Opal Suarley
Opal Suarley is one of the pre-created, yet unplayable Sims in the Sims 3. She is deceased before the game starts. Apparently, she was young when she died, in her child stage. Her blue ghost indicates that she drowned to death. She is buried in Pleasant Rest Graveyard. It is unlikely that she even had a lifetime wish, and as a child she would be unable to accomplish it (assuming she had one), so her gravestone is very small. She has blond hair tied in pigtails. She can be ressurected by making her eat Ambrosia, and waiting for her to age up to the Young Adult life stage, and then befriended or married. Or she could be added to the active family via a cheat as a ghost.
