A Monkey Archer is a monster found on Ape Atoll and features heavily in the Monkey Madness I quest as well as playing some role in the Recipe for Disaster quest. Its bones are necessary to make a small Ninja monkey greegree. They attack with ranged from small platforms.
Despite the fact that they are on platforms, they can be attacked with melee, and their bones collected from said platforms, although this action is acted as obtaining an item from a table (the player slightly reaches forward to grab the bones). As with all creatures on Ape Atoll, Ninja Monkeys are not aggressive when holding any sort of greegree.
