The wombat is a large, solitary and nocturnal relative of the koala, native to Australia. It has poor eyesight but an excellent sense of smell, which is its main navigation aid.

It also has a very strange ability under its belt: its shit comes out in cubes. Yep, unlike other animals which produce cylinders (eg. dogs), pleets (eg. rabbits) or splats (eg. cows) the wombat’s turds really are cube-shaped.

Why? Well it seems it is all down to the physiology and motility of their large intestines. But it turns out it is also a useful attribute to have.
