I'm trying to complete that advanced rainforest (Puenta Arenas I think) one where you have to have an exhibit rating of 90 for all exhibits. So far I'm doing great but I'm having serious problems when I try and add any more animals! The enclosure I'm trying to have happy animals in is huge and I customise it to suit the animal's needs (I always check to see if I can add more things or change some more terrain after the keeper says that everything's OK). So far I've tried Blackbuck (who I can get up to 89 but no further), Elephants and Hippos. Is there a guide anywhere that shows you how to make ultimate exhibits? I don't quite understand how it all works.
