Lets talk about the bats now. The Australia House in the real zoo does have fruit bats in it, so when I built this house originally, I allowed for these to be added later if the game ever added them....and here we are.
Well, the space I allocated was not working with the fixed size of this new walk-through exhibit. Mostly I was having issues with the hit box of this. I tried everything I could think of and could not get it added at ground level. So, I had to raise it, but I'm happy with the results. Had to reform the building and roof a bit to get it to work, but was able to have a raised walkway and a ground level walkway (technically this walk is below the exhibit, not in it, but with the walls removed, it all looks like one huge walk through.
This was the original flat hallway. Added the ground level path entrance on the lower right, and added ramps/stairs up to the raised pathway (actually in the exhibit).
