This has been discussed in the past, and considering lack of available space, the only way I see a worthwhile South American precinct eventuating is at WORZ. A North American precinct was also brainstormed which could tie in well, and Werribee still have a quarter of unused space. I could easily see growing Wild hold penguins and arboreal mammal species. If Wild Sea was to be demolished, a tropical dome featuring caiman, Philippine croc and gharial if not at the TOTE would be optimal, among other species. Potentially if one species of caiman was held at WORZ with the rest of the precinct, say spectacled caiman, and the largest member of the alligator family, the black caiman could be held in this dome. If said done was crocodilian-centric, I’d see it entirely plausible for a small pool to hold Cuviers Dwarf Caiman. Having 2 large species of crocodilian, 1 medium and 1 small would be a great addition and none of those species take up an overly large amount of space, and should be able to fit within the current are. This is made easier if both levels were retained
