realley a nice building. it could be very nice if you can make one of thise to aquatic animals, i can not get it to work to water animals. Very nice buildings/habitats :)

I just keep getting terrain mod failed and I'm not sure what I'm doing wrong

FYI - locking in the interior staff village causes alerts to be generated saying that the water & power facilities are inaccessible, to fix this a staff path needs to be laid between 2 of the habitats and joined to the exterior pathing (this reduces the size of one habitat slightly)
The facilities are actually accessible but the game AI doesn't recognise this unless there is a connection to the main zoo
