How cute is this little critter?
It's a Quokka.
In regard to their name, apparently North Americans usually pronounce it kwo-ka (rhymes with “mocha”), and everyone else says kwah-ka (rhymes with “wokka wokka”). It’s really up to you. Quokkas don’t care
Quokkas come from the same family as the kangaroo
(called Macropodidae) and they live on a handful of small Australian islands such as Rottnest Island and Bald Island.

They don't seem bothered by selfies.
But remember, anybody caught even handling or feeding them can be issued a fine of up to A$300. And no, before you ask, you cannot keep Quokkas as pets.

The rat-tailed clan makes its home in swamps and scrub-lands, tunneling through the brush to create shelters and hideouts, emerging at night to find food. And again, no you cannot have one as a pet.
