The wombat, a sturdy burrowing animal from Australia, is the only known creature that produces cube-shaped poop. It can make up to around 100 neat cubes in a single night.
Scientists found the cubes are shaped inside the wombat’s very long intestines, where different stretchy and stiff sections mold the droppings into flat-sided blocks.
Why bother? Wombats stack their poop on rocks and logs to mark their territory by smell - and cubes are far less likely to roll off than balls would be.
