There aren't a lot of animals in Planet Zoo in the North America, they mostly come from the tundra of Alaska to the Central America. I would love to see animals that are focused around the North America area, like mostly the United States. And I would love to see Multiple cities based on United States theme stuff, like from Boston to Seattle. And the animals aren't limited to 4, like here are some good examples of animals to add:
