And they have SQUARE poop!

In addition to scent markings, or scents produced by the hormones that animals release, wombats leave their cube-shaped scat as territorial signposts on the tops of rocks and logs. That distinct shape is beneficial since the flat sides of the cubes keep the droppings in place on their precarious locations.

How freakin' cool is that?
