Tbh out of that roster the only ones that interest me are the tree roo and the nene. An habitat iguana would be nice Indeed though, but i deffinetly don't need anymore English domestics and even if it is not English, deffinetly not another pig. A Victoria crowned pigeon would be much more interesting than any oh them, Caribbean flamingo and brown pelican would work for Caribbean Rep while adding more birds and variety and we are also missing the aye-aye for Madagascar, which looks and behave very different from the other lemurs we have and it is fairly requested. And please not the creepy macaque
So for me a good Islands animal pack roster would be
- Tree kangaroo (Australia/ New Guinea)
- Victoria crowned pigeon (New Guinea)
- Brown pelican (Caribbean Islands)
- Nene goose (Hawaii)
- Aye-aye (Madagascar)
- Marine iguana (Galápagos)
- Japanese serow (Japan)
- Ex: Coconut crabs
You get three birds, 1 primate, 1 arboreal marsupial, 1 reptiles and 1 obligated ungulates.
That said i think an Islands pack is extremely unlikely after Oceanía and Tropical.
