Instructions
Go to the Kaya Forests. Use your Opuntia Fruit on the giant tortoise shell. The tortoise will get up and walk left to get the fruit. It's assumed that you already got the Opuntia Fruit from the Mountains of the Moon at the beginning of the level.
Use your shovel on the ground where the tortoise was sitting. You will receive an Ebony Elephant figurine and two ghosts will appear.
Talk to the ghost on the left. He will ask you to bring a Fingo for a reward.
Return to the plane and fly to Nabooti. Talk to the woman in a blue outfit and trade the elephant figurine for a Fingo.
