This is not a quoll but it is a marsupial. It is Sticky the Quokka from Perth Zoo.
Sticky’s is a sad and bewildering story. Someone kidnapped him from Rottnest Island for unknown reasons but ended up dumping him in Kings Park next to Stickybeak Cafe which is where he gets his name from. He was brought to Perth Zoo and has lived there ever since.
Sticky shares an enclosure with Norbert the nabarlek and a hyperactive woylie.
