How do i get the blood talisman in Murloc RPG Stranglethorn Fever?

Ahh, yes thats the one where you have to seek out the witch doctor in STV. He will ask you to get a gorilla fang, just simply keep killing gorillas until you loot one then bring it to him. Then from there on you will be doing a series of gorilla kills until you go against mokk. and he is very easy. Then you get mokks heart. From there on out is all talk and deliver.
