I didn't really have time to make a professional zoo, as I got my computer to play it on October 2nd, but yesterday I finally decided on making a Gharial Oasis, where I got to try out the waterfall mechanics and use elevated walkways for the first time. I wanted to add some more features to it, like underwater viewing and more land space for the Gharials, but today when I got to my computer, the beta has already ended. It was an easy exhibit to make, and I plan on making it in sandbox in November.
