Here's a Mountains/Highlands/Alpine scenery pack that seems most probable to me:
1. Markhor - Face or the pack, dare I say flagship animal, presence in both Zoo Tycoons, very iconic look
2. Wolverine - Top 3 in both meta-wishlists, rose in demand after NA and EU pack, this would be the 2nd fan favorite spot of the pack
3. - Rock Hyrax/Alpine Marmot - I tried to limit myself to only two fan favorites, while still going for something that the major crowd would appreciate. I feel like both animal "inhabit" that niche of a cute, mountain dwelling plush toy
4. Rocky Mountain Elk - This is that "but why" oddball inclusion, around 40th place in Meta-wishlist, popular on Nexus, it wouldn't be a PZ DLC without species to moan over
5. Pancake Tortoise (E) - Always struggle with picks for mountain exhibit, this can be a very nice but easy pick, I don't think many would be against an exhibit tortoise
I tried to go for a realistic route, that means not overcrowding the list with fan/community favorites: Spectacled Bears, Takins, Geladas, Pallas Cats...I went for the most popular mountain animal on wishlists (Wolverine) and then for the most marketable of favorites (Markhor), but that one is highly subjective.
Even tho we definitely had packs to bring all four highly wanted species (Africa, Conservation, Europe in a sense), that seems to be the more optimistic rout, so I tried to manage expectations.
Also as almost every pack seems to have that one unpopular pick (Dama, Water Monitor, Wildebeest, Lechwe, Skunk...) I tried to go for something that could still make it into pack realistically while also being something so out of left field.
