If the final pack can really be 12+1, that would be awesome. This is way more than I expect to happen. I especially went overboard with additional updates and building pieces, but oh well. My wish list, trying my best to stick to the rules...
1. Grey Crowned Crane
2. Spectacled Bear
3. Blackbuck
4. Sea Otter
5. Greater Rhea
6. Patagonian Mara
7. Spider Monkey (any)
8. Alpine Marmot
9. Roseatte Spoonbill
10. Watussi Cattle (obligatory domestic BUT if it's not needed then I would say Olive baboon)
11. Goodfellow Tree Kangaroo
12. WE: Scarlet Macaw (+ Hyacinth Macaw and 1 or 2 others if possible) although I would be equally happy with just a normal exhibit with any chameleon or cobra.
