Enraged Silverback Gorilla

Enraged Silverback Gorillas do not spawn naturally. They only spawn in a cave in the Cape of Stranglethorn after you turn in The Heart of Mokk at Witch Doctor Unbagwa. This gorilla constitutes the first wave on the way to acquiring Heart of Mokk.

Quests
While the player is on Stranglethorn Fever, he can turn in one at witch doctor Unbagwa, who then spawns three waves of mobs. Enraged Mistvale Gorilla resembles the first wave, the second being Konda and finally Mokk the Savage.
