:sun Thanks for the kind words everyone!
Now there WERE one or two little hints of what the next biome might be in a few other screenshots, but now the secret's out:
The zoo has decided to split from the flowery theme for a bit and has built a few very special Tundra exhibits!
The first exhibit is adjacent to the Panda/Gibbon exhibit and features Artic Wolves.
Here's an overview that also shows the adjacent Tundra guest area. It connects to a Sky Tower and an alternate Spanish Lynx viewing area.
This alternate overhead view shows a different angle. The elevated paths are made transparent, and you can see that the Sky Tram is now operational.
