Use one of the following methods to obtain the rare Voodoo Doll item. Note: The Voodoo Doll requires Level 1 Mischief skill to use, and increasing the skill level for Mischief will give your Sim better results with the Voodoo Doll.

Hunting for Treasure: Keep digging for treasure to eventually find the Voodoo Doll. To dig, travel to public spaces around the neighborhood. Search for piles of rock deposits, and use a shovel to interact. You will find randomly generated items and treasure maps to unlock collectible MySims statues.

Rare Pond Fishing: Travel to the Desert Bloom lot in Oasis Springs, then move toward the public space behind the park where there is a rock canyon leading to a boarded up cave entrance. Along the rock walls are tiny ponds that you can fish in. Keep fishing in the ponds until you obtain the Voodoo Doll.
