I hope frontier at one time brings out more specialized bigger animal buildings to the game.
Butterfly/Moth garden, we have such in two zoo's in the Netherlands, it's a huge walk-through garden where all types of butterflies fly free between the beautiful plants and visitors.
Bat Cave, where people can walk through and see different types of bats, I don't know if people can walk through the bats as bat- is dangerous to humans, but you get the idea of a bat cave!
Bigger bird cages, like for eagles, vultures and owls.
Aquatic route with rays, sharks, many fish ect ect
What other of these type of cages would you like?
