This is not a quoll but it is such a close relative that some of them have spots like quolls. It is of course a Tasmanian devil.
I’m not sure what to say about Tasmanian devils that hasn’t already been said – yes they’re real, no they’re not just cartoon characters, yes they’re only found on a pudendum-shaped island south of Australia for the time being, yes they’re in danger of dying out from a communicable cancer called Devil Facial Tumour Disease, no it’s not cured yet, yes they’re trying to cure it but Tasmanians are running over the vaccinated ones for some reason.
