Monkey Zombie

Zombie monkeys are encountered during Monkey Madness in the Ape Atoll Dungeon.

They drop (Zombie) Monkey bones that are needed to make a Zombie greegree.

Lvl 129s, along with 82s can also be found under the Temple where Monkey Guards are located.

Zombie monkeys appear to be green undead monkeys. They are the fastest ranged experience in the game when using red chinchompas since they spawn on their own bones.

Training
If you have a high enough prayer and combat level, these monsters can be used for training. With a high prayer level and combat level, you can get around 100k experience per hour. Use prayer, and when you are out run upstairs and use the alter. Make sure, however, to become a monkey using a greegree or you will be trapped by the larger monkeys up the ladder.
