I have nearly completed all the holiday memories but I can't seem to find the one 'Uncovered an island secret'. I know that it is the VooDoo doll but I don't know where I can find/get it! Please help me. Thanks in advance! x

First, dig until you find the map to the Mysterious Hut. Then go on an island vacation and go to that secret lot. I would suggest that you train your sim to get high mechancial skills before going on vacation. At the hut you will meet the witch doctor and he's having a bad day because a lot of his appliances have broken down. You have to fix everything while the bastard goes off and takes a nap. After everything is working, the witch doctor will reward you with a voodoo doll.
