The Ninja Monkey (referred to in files as the Lemur, which it more closely resembles) is an unlisted wild animal which only appears in Operation Neptune, a Boosterpack mission. It is very strong, with a good melee attack and a ranged attack using thrown bananas, and has good armour.

Due to their strength and numbers, they are very difficult to kill, but they each yield 100 skulls upon death.
