Forgot to answer this part.Also, what are your opinions on the state of masupials as a whole in the game?
Obviously a tree kangaroo is needed. It is a very highly requested animal. After that, most of the options are tiny or something resembling a kangaroo. Personally, I would be satisfied with just the tree kangaroo. However, I know there are quite a few players from Australia who would want/need more, and there are still some options that I like. For tiny marsupials, the main set I've heard people talking about are the bilby, brushtail possum, numbat, quoll, and cuscus. About 3 of them would be great to have. The greater bilby, aka the Australian Easter bunny, seems culturally and conservationally significant, so it would be a strong pick. The brushtail possum has a bright yellow color morph that looks like pikachu, and it is a popular "backyard buddy" animal for Australia, from what I've heard. Numbats, quolls, and cuscuses also seem cool, so I would not mind their inclusion either. For macropods other than the tree kangaroo, the yellow footed rock wallaby is visually distinct and would add an arid wallaby. It has decent support, and I think it would be a great addition. I would be completely satisfied with just that one, but there is also some demand for the grey kangaroo for a temperate kangaroo. I think it would be an ok but kind of boring addition. After a fourth kangaroo/wallaby, I will be out of patience for further clones, and support would have to go on for quite a while for me to feel remotely excited about another one.
