Hi Ken,

It appears that there is no clarity on the animal's actual 
origin, so South America is not a givem. If you look closely 
at the photos of the marsupials you suggested, you will 
notice that they have more complex ear structure, compared 
to the beasts on Yen's pictures and usually a longer muzzle. 
The short cuddly muzzle of Yen's creatures is pretty 
suggestive of a rodent. Besides, opossums do not tend to get 
fat in the body, because they deposit fat reserves in their 
tail (don't know about burramyids, honestly). Please check 
out the photos of the European forest dormouse, Dryomys 
nitedula, for comparison:


I would bet a substantial sum that it actually is a 
Dryomys... I have seen them alive and know that they do well 
in captivity.

Best wishes,
