The South American Animal Trail
Location: The Boneyard
Entrance: old colonial looking Argentinian building would be surrounding a rainforest entrance.
Enclosure 1: you would enter a dense rainforest with a large river going through it. The animals you would see would be a variety of snakes with the main snake being a anaconda.
Enclosure 2: you would enter an old Brazilian temple and see temple ruins around a family of ocelots with plenty of branches to lay on. You would enter a room with a broken roof where you would see jaguars.
Enclose 3: leaving the temple you would go through large rock caverns seeing capybaras, anteaters, and local animals from northern Argentina.
Enclosure 4: after leaving the caverns, you would see large trees and rock outcropping. You would hear the sounds of parakeets and other local birds from the Amazon.
Exit: after leaving the parakeet enclosure, you would exit into a Guatemalan village probably connected to the open air market.
I gonna go ahead and steal an idea that parts of the enclosure would be next to the Indy queue. With the parts of the trail being themed around old Incan temples with different traps.
