If some of the trees are removed for easier viewing, Lemur Island could be a place for Gorillas but it seems like a whole new building would be built. This seems like a stretch but maybe a complete refurbishment of Monkey Islands into a Gorilla house and move the Mandrill to the Spider Monkey enclosure at the entrance but this may be too small. Also the Savanna part of the Spirit of the Jaguar could become an area for the South American species and then maybe moving the Lion Tailed Macaques to Lemur Island. However I see a massive array of problems with this and it would be extremely expensive because I doubt Monkey Islands is at all Gorilla proof! Also a refurbishments of the Spirit of the Jaguar savanna would be expensive for the same reason. But it's a fun idea and I would like to hear what others have to say.
