I killed a monkey on karamja, right beside the volcano. Used those EXACT BONES with the talisman to make the monkey greegree. Equipped the greegree and tried to talk to the sergant and he said I need karamjan bones.

 

 

 

I would love for someone to explain this to me since I believe there is only 1 karamja and I was there.

You don't make the greegree, you take them to the mage in the large caves to get it made.

I think you get a monkey corpse from the Karamjan monkeys. Just go back to Karamja and kill another monkey and see if you get a corpse. Then bring it to Zooknook in the Ape Atoll Dungeon.
