There's a new challenge waiting for you in My Free Zoo: the Amazonian Collection. You'll find it in your achievements menu which you can access by clicking on the trophy in your main menu bar.
There are two parts to the Amazonian Collection: Amazonian Land Animals and Amazonian Water Animals. For each of these tasks, you need to breed 10 specimens of specific Amazon animals and release them. These include jaguars, marsh deer, giant otters and Amazonian dolphins.
As soon as you've bred and released all required animals for each part, you'll get a Bald Uakari. This special Amazonian monkey has a scarlet face. Bald Uakaris live in groups in the treetops and feed primarily on fruit.
The Uakari can only be obtained through the Amazonian collection. Each part (water and land) will give you one Bald Uakari. Upon completing both parts, you'll have two Uakaris to breed!
Come stop by your zoo! You'll find everything you need to know in the game!
