Personally i would have love if frontier had put 1-2 natural looking waterfalls für the Enclosures and 1 for the Lagoons instead to give us some more artifical fountains for enclosoures and even one for the lagoons !I can really only build hills in enclosures, and still-water ponds. Waterfalls connecting higher- and lower-terrain water spots would be super cool!
Caves and Waterfalls as well as Waterfiltration system ( for more or less clear water ) are part of the "Decorations" from Frontiers Planet Zoo since Day ONE !Animal happiness being a factor in the game, it would make sense to be able to decorate enclosures as much as guest areas. In zoos there are waterfalls, caves, and sometimes items in the enclosure to keep the animals happy. It would be nice to add caves and waterfalls to both decorate the enclosures and guest areas.
Really nice Waterfalls !
