Role-playing games, and fantasy/scif-fi in general, exhibit creatures of a huge variety of types. There are reptiles, amphibians, insects - even crustaceans have representatives. But for some, inexplicable reason, there is, as far as I can tell, a distinct lack of marsupials.
Why is this? Marsupials are intriguing. Pouches, somewhat bizarre genitalia, and more - see Wikipedia:
Marsupials.
So my challenge is this: Create some intriguing sort of creature which is distinctly a marsupial. It can fit into any genre or be of any level of intelligence. It just needs to be a marsupial.
(My apologies for any butchery of biological terms in this post).
