Everybody say awww!
The quokka is a marsupial in the same family as kangaroos and wallabies. Both ridiculously adorable and prone to standing on their back legs whilst rubbing their forelimbs together in contemplative scheming. (See photo for reference.)
The quokka is almost endangered, being on the "vulnerable" edge of the spectrum.
Native to Australia, the quokka has no fear of humans and has been known to waltz right up to them out of curiosity. To bring harm to a quokka results in serious fines, so pet him nicely! Actually, don't pet them at all, because you can be fined for that as well.
