These have been known to very rarely drop a fire skull or mystery box. The mission chain has been disabled since NI has had codex, there is NO codex for these, yet.
Another Secret Island exclusive mob! These drop the CND Banana that you will need to travel back to Rock.
‘Do it for Archie’ is the mission chain for gorilla kill points and a very nice source of great skill rewards.
These also drop the Skull keys for the ‘Temple Runs’ to collect the goodies for the Zombie Vaccine for the Biodome, and if you are lucky in the waves and with the KONGs you will get the ever so rare and valuable Kong Bloods.
OH! Did I mention the Gorilla Pets? The tamable just spawn where you are killing gorillas.
Gorilla Pets – Island Gorillas – Mountain Gorillas – Kong Gorillas
