Instructions
Go to Blue Nile Falls and collect a lilac from the banks of the falls. Head to Nabooti and trade the flower at the trading post for the turban. Equip the turban. Travel to Giza; you'll be given a shovel.
Travel to the Mountains of the Moon and jump up to the trees. Speak to the woman; she will ask you to help her with the cactus on the cliff. Jump up at the cactus on the next screen to loosen it; collect the cactus pear.
Travel to the Kaya Forests; give the cactus pear to the tortoise to lure it away from the mound on which it is sitting. Use the shovel to dig in the location where the tortoise was sitting to get the Ebony Elephant artifact. Take the artifact to the artifact hunter in Nabooti.
