Meet The Happiest Animals On Earth Named Quokkas

You have most probably already seen a photo of a quokka floating around the internet - cue the 'quokka selfie'. This animal's peculiarity is that its smile can make even the stoniest heart melt. And we can see why. Quokkas come from the same family as the kangaroo (called the Macropodidae). They were once found on mainland Western Australia but are now mostly found offshore on Rottnest Island (near Perth) and Bald Island (near Albany). However, there are still a few isolated groups inhabiting the bushland that surround the city of Perth and the mainland.
