This was currently the only live (captive) display at the Wetland Park - all the indoor areas were under reconstruction.
The artwork on the right is flat (on the ground and on the wall below the window) but looks three-dimensional so visitors can take photos of themselves "interacting" with the animals and waterfall. It can be seen better in this photo: Saltwater Crocodile (Pui Pui) enclosure - ZooChat
