Tree kangaroos! Kangaroos in trees! Voluntarily!
Tree-kangaroos (Dendrolagus sp.) are nocturnal, arboreal, and primarily herbivorous. They’re not super-big*, but they don’t have to be when they land on you from like five fucking stories up a goddamned tree. Australia, guys. (And also New Guinea, but shhh. New Guinea’s successfully stayed on the down low with weird animals.)
They use those honking long tails for ballast, so they can keep their balance when just flitting about the treetops like it wasn’t any kind of fucking thing. They’ve got like sandpaper pads on their paws and huge claws to help them keep a grip on tree limbs.
In spite of having some pretty bonkers claws on their forepaws, they’re actually reasonably dexterous, and they use them to manipulate fruit and leaves while they’re eating.
Challenge: Do cute human things with your paws.
*Like thirty pounds maybe. So, you know, big when it’s landing on you but capable of fitting in a not-tree kangaroo (6’+, 200 pounds)’s pouch.
