To be honest, a lot of animals could have came in multiple different DLCs. So I’m gonna just list the biggest contenders and then say what DLCs they could have come in.
- Hamadryas Baboon: Arid pack, Africa pack, and Grasslands
- A duck species: Wetlands, Aquatic, North America, Eurasia, Europe, Barnyard, and I could argue Tropical
- A Pelican species: Wetlands, Aquatic, North America, Eurasia, Europe, Australia, and Oceania
- Secretary Bird: Arid, Africa, and Grasslands
- Grey crowned crane: Arid, Africa, and Grasslands
- Musk Ox: Arctic, North America, Europe, and Eurasia
- Any of the Pink Trio (American flamingo, Roseate spoonbill, scarlet ibis): South America, North America, Wetlands, and Tropical
- Golden lion tamarin: South America, Conservation, and Tropical
- Howler monkey: South America, and Tropical
- Coati: South America, North America, and Tropical
- Echidna: Australia, and Oceania. Maybe grasslands considering the wallaby and emu were in it.
- Monkeys (whole group): pretty much every pack we could have got another monkey, exceptions being Aquatic, Arctic, and Barnyard.
- Blackbuck: Grasslands, and Eurasia. As much as I would like to say Arid, Arid is North Africa focused so in hindsight it wouldn’t work.
