I already finished Monkey Madness and i have this monkey amulet but i want to know how i transfor in other monkeys like zombia do i need anything??

to make another greegree, you need a monkey talasman and the bones of the monkey you want to transform into. You can buy many talasmans at the rune shop on the island. I would suggest getting like 3 of them and the bones of a ninga, gorila, and zombie. All of them come in handly later.

 

Just bring all the stuff to the mage at the end of the tunnel.
