Level 129s and level 82s can be found under the Temple where Monkey Guards are located. The level 82 version are actually called Monkey zombies and are smaller. There are also level 98 zombie monkeys located in the inaccessible room under the Marimbo Temple (accessible after the Hard Western Provinces Diary is complete). They are also located in the cave with Skeleton Monkeys. Monkey zombies appear to be green undead monkeys.
