As another way to make enclosures more unique, what if the existing viewing gallaries, of all types; or at the very least, the lagoon. The viewing lagoon in the movie had this huge viewing gallery that encompassed multiple ones connected together. Unfortunately in the game, the viewing gallery is smaller and if you place multiple ones they are far apart. What if they could be made modular? Just like the lagoon and the aviary you start with one, and if you like, you could make it bigger by adding as many as possible.
