Gorilla bones (called Monkey bones in-game) are the bones bones dropped by the level 89 Monkey Guards that inhabit the Temple of Marimbo on Ape Atoll. They give 18 Prayer Experience when buried, although their main function is to be paired with a Monkey talisman and exchanged with Zooknock (found in the Ape Atoll Dungeon) during and after the Monkey Madness in order to create a Gorilla greegree.
If players wish to create a bearded gorilla greegree, they must use Monkey bones (bearded gorilla) instead.
