We'll retweet the answer from @PopSci and also update this post so your amazing animal knowledge will be permanently etched onto the internet. Show your kids! Your dumb kids who thought that was a baboon!Update: And the winner is...@TaraBethIdaho who correctly guessed that this creature is a cuscus! Cuscuses are marsupials native to the far northeastern corner of Australia as well as New Guinea and a few other islands stretching as far as Sulawesi. Cuscus is the word applied to a few species of possum in this area as opposed to the more common possums native to the rest of Australasia like the brushtail possum. This one in particular is a common spotted cuscus which is found throughout that small cuscus range. (Other cuscuses like the Sulawesi bear cuscus are limited to particular islands.) It's about the size of a big housecat and lives in the dense foliage of trees from rainforests to hardwood forests to eucalyptus forests. It has an opposable thumb and a prehensile tail making it a very good climber but it moves pretty slowly so it's often confused for a sloth or a loris. It is very fluffy! Hi cuscus!I will name is 'Adorable' and love it and hug it and take very good care of it! SQUISH! Hug! Hug!
