This is the best pack no doubt, i am going to show you:
12 Animals: The highest of any pack YET, this means potencially larger packs on the future so we can finish that up (like Aviary or maybe even aquarium)
Multiple Species in Walkthrough Exhibit: This means that if we ever get birds, some are going to be very well multispecies animals, maybe no carnivorous ones like raptors but the rest could.
Many highly requested animals added: Maned wolf, Caracal, Emu, Nine Banded Armadillo, a Wallaby, FIVE butterflies, truly a good selection.
No secretary birds: Yep, no secretary bird, it seems they are hanging it for some reason, but i believe, with the butterflies multispecies and no secretary bird, it is guaranteed we will get an aviary pack (to let you know, the secretary bird lives in grasslands and was even more requested than the emu), but another thing to say is that no flying birds were added either.
South American and Oceanian further representation: Oceanian and South America is a third of this pack, and there are 12 animals. Also oceania is only missing one mayor land animal, the Tasmanian Devil, while South America is missing only 2 now, the spectacled bear and a sloth.
Middle Eastern Representation: The Middle east was barely represented, the only animal you could really say was there is the Cheetah, but in less than 2 weeks, you will be able to add the Caracal and the Striped Hyena in your Zoo.
More Burrow Animals: Now, this one is not as important, but when burrows released, they were practically useless. Now, they are one of the best if not the best shelter with small animals, with the armadillo being another addition.
Another Career Scenario: The second one after release, not really important for me, but some people really value this.
That's all, folks, that is why this is the best pack yet.
