This requires conversion of all of the purple masked masters ("Physician, Heal Thyself", "Organic Farming", "Go Speed Racer, Go!", and "The Proof Is In The Pudding" puzzles completed), all pieces of the necklace, and several children. After each of the purple mask conversions, have a child take the piece of the necklace that they dropped to the statue. The child who brings the last piece will assemble the necklace. This necklace belonged to the chief's daughter. Once the necklace is complete, drop someone (adult or child) on it to take it to the chief. The chief will convert and join your tribe. The former chief is a master in all six specialties.
