Monkey bones (big zombie)

Big zombie monkey bones are a form of monkey bones that can be obtained by killing level 108 and 110 monkey zombies in the Ape Atoll Dungeon or in the cave beneath the Temple of Marimbo. They give 5 Prayer experience per bone, as opposed to regular bones 4.5.

Like most monkey bones, they can be used to make a Greegree by taking it to Zooknock in the Ape Atoll Dungeon. Using these bones will create a Zombie monkey greegree (big). Besides the type of resulting greegree and inventory icon, they are functionally the same as Monkey bones (small zombie), which are used to create small zombie monkey greegrees.

Oddly, despite being being the same size as other monkey bones, they have a smaller inventory icon.
