This requires the mausoleum to be completely cleared ("Dem Bones" and "The Bigger They Are, The Harder They Fall" done), random adults, and fire in the fire pit. When you have finished clearing the mausoleum, a shallow pan will appear on the steps. Drop an adult to pick it up. The adult will take the pan up the stream and drop it near the mysterious pot, halfway between the food bin and the science lab. Drop an adult on the shallow pan and they will start to pan for gold. If they are successful, they will fill the pot a third of the way full of gold. Keep dropping adults on the pan and panning until the pot is full. When the pot is full, drop an adult on it and they will take it to the fire. Wait a bit, and the gold will turn into a large orb. When it does, drop an adult on it and they will take it to the Blind Totem at the edge of the forest. When they put the eye in the totem, the hidden section of the forest will clear and you will see the chief.
