Two paths--the first is to keep the African theme but rebrand it as a Safari Pack, the second is to keep the desert theme but have it represent deserts around the world.
Safari Animal Pack:
Black rhinoceros
African crested porcupine
Dama gazelle
Grey crowned crane
Secretary bird
Mantled guereza
Sulcata tortoise
Gaboon viper (exhibit)
Arid Animal Pack:
African crested porcupine
Dromedary camel
Addax
Hamadryas baboon
Patagonian mara
Chacoan peccary
Ratel
Budgerigar (walkthrough)
I think they went with North Africa specifically because they gave us an entire theme for it in the African Pack but almost no animals to use it; I guess they decided to give us the species to make the theme more usable. Fully agree they should have named it something like the Sahara pack though.
