This Achievement Is For Catching A Gold Colored Macaque In Hoarfrost Reach.
- The Macaque Spawns In Area 6, At The Hot Springs.
I Found It The First Time I Looked, After Talking To The Endemic Life Researcher In The Area.
- First, I Caught, And Turned In, The Three Penguins And The Bone Fish Research Requests.
- The Next Request Was To Find The Golden Monkey, And There He Was.
(Area 6, Next To The Lip Of The Hot Springs, Running Around With Other Monkeys)
- Use The Ghillie Mantle If You Do Not Want To Chase It.
I Did Read Somewhere That You Can Find One On The Quest "Monkey Bussiness" After You Beat Furious Rajang. But I Can Not Confirm.
Good Luck!
