Before going to the Kaya Forests, you need two items from other locations. They are :
Get the shovel from Giza, Egypt.
you give it to the turtle in kaya forests then you dig where it was laying
Dig where the turtle is sleeping. You need the Opuntia fruit (cactus fig) from the trail at the Mountains of the Moon.
You give the lady on nabooti an ebony elephant for a fingo. You then go to kaya forests and give the turtle the opunta fruit. You go to the area where the turtle was sitting and you will see a hole in the ground. You use the shovel to dig in the hole to make a bigger one. two ghosts will appear in front of you. They will say "Who has awoken us". You give them the fingo you got from the nabooti lady. They will give you the green jewel in return.
Dig up the ebony elephant from where the turtle was sleeping at the Kaya Forests, and swap it for the fingo at Nabooti. Then give it to the ghosts and they will give you the green jewel.
if you already moved the turtle then use your shovel to dig where the turtle was
The "pot" is probably the missing "fingo" talisman, which the spirits of the Kaya Forest are seeking. To get the fingo, dig up the Ebony Elephant from where the turtle was sleeping and swap it for the fingo at Nabooti. (see related question)
Dig where the turtle sat and you will find an artifact there (the ebony elephant). The Kaya spirits are seeking their lost "fingo". Go back to Nabooti, to the lady who trades ancient artifacts, and trade the elephant for the Fingo. Take the fingo to Kaya and you will receive the Green Jewel.
The turtle is sleeping at the Kaya Forests. You will need the Opuntia fruit (cactus fig) from the trail at the Mountains of the Moon. Lure the turtle and dig where he was sleeping.(Get a turban for the blue lily from the Blue Nile Falls, and wear it at Giza to get a shovel.)
You go to the place where the turtle is... give the fig to it and it will move... go to where the turtle left a hole... dig and you will find two people... you will have to get something to trade at nabooti and give the vase- like thing to them and they'll give you a gem!!!
There is nothing IN the turtle, but there is something UNDER the turtle. To dig where the tortoise is sleeping, get the cactus fig (opuntia fruit) from the path at the Mountains of the Moon. Use it to lure the tortoise. To get a shovel, get the blue lily from the left side of the Blue Nile Falls, and swap it for a turban at Nabooti. Wear the turban at Giza to get a shovel.
The Ebony Elephant. To get it, you have to get the "opunita" fruit or cactus fig and give it to the turtle (you will not see it), and he will reveal a very small hole. Then, you need to get the shovel on Giza. To get the shovel, you need to get the desert turban and then a guy that looks like a ninja will give you a shovel. Once you have the shovel, dig the hole with it and you will get the Ebony Elephant.
