Happy Guests
Put more than 1 species of animal in an exhibit. This makes your guests more amused and keeps them more happy because they have more to see. Also they sometimes comment on how they think it's great that two different species can live together. I have writen a list below of animals you can put together.
Savannah
Giraffe, Zebra, Ostrich and Giant Sable Antalope
Temperate Rainforest
Giant Panda, Red Panda, Koala and Common Peafowl
Grassland
American Bison and Prezwalski's Wild Horse
Tundra
Penguin, Polar Bear and Caribou
Desert
Fennec Fox, Dromedary Camel and Scimitar Horned Oryx
I haven't figured out if you can put the any of the other animals together but makes sure you don't put any more animals than I have listed in each exhibit. Happy Tycoonin'!
