The last 4 indoor exhibits of South American Rainforest are probably the weakest part of the building. The first exhibit is a small one for 18.0 Common Vampire Bats, but they mostly just hang on the rocks in their exhibit. Then there is an Emerald Tree Boa tank that is very basic, with 2 branches, a mural in the back, and the lower part of the tank glass is incredibly fogged up. Then there is a vertically tall Amazon Milk Frog exhibit, but the ground space is very small, and last is this small Pygmy Marmoset exhibit.
