It absolutely does matter how many countries there are. And what they think is relevant. You don't think it's relevant that other countries accept different continent models? You sound like you're having a tantrum lmao.
For the record no one on earth is saying "I wonder what New Zealanders think" about any topic. Not even Niue. It's why you keep getting left off the maps.
The irony of claiming someone is throwing a tantrum and then resorting to ad hominem is lost on you I see. Attacking New Zealanders does nothing to help your argument. As I've said before I'm completely fine with people following different continent models, but this is way out of line and not conductive to discussion at all.
Thank you and now tell me a cool animal from neuginea or another island
To get things back on topic, here are some cool Papuan animals that haven't been suggested yet but could also fit into a New Guinea Pack.
White-striped Dorcopsis - Dorcopsis are some of the weirdest looking macropods, and they actually resemble some of the earliest fossil macropodids we know of. They're now only found in New Guinea and several neighbouring islands, and currently span 6 species. The White-striped Dorcopsis is the one that usually jumps to mind for me in terms of zoos although I know several other species are kept in captivity as well.
Agile Wallaby - For something larger and a little less odd, there's the Agile Wallaby. Also widespread across northern Australia, it's the only member of the "typical kangaroos and wallabies" (former
Macropus genus) to extend into New Guinea, inhabiting the Trans-Fly savannas and woodlands in the island's south (which are an ecosystem much more reminiscent of the drier mainland than the rest of New Guinea).
Frilled Lizard - For another species more typical of northern Australia but also occurring in the Trans-Fly, there's the Frilled Lizard. A New Guinea pack could be another way of sneaking it in, although I imagine it may be in better taste to include a more iconically New Guinean animal as the single exhibit species.
Amboina Sailfin Lizard - Reaching over a metre in length, this is the largest species of agamid in the world and would be a really unique inclusion as either a habitat or exhibit animal (or both?). Just look at them.
Northern Cassowary - While we've already gotten a species of cassowary in the game, New Guinea has all three of them so what's the harm of adding another? Both the Dwarf Cassowary and Northern Cassowary are quite different visually from the Southern Cassowary in their own unique ways, but I've gone with the northern here just because they can be so goddamn weird looking.
