Wombats excrete tiny, cute (???) little cubes of poop every night, leaving up to 100 of the smelly squares around their territories. The poop's distinctive shape is no accident: it makes the pieces less liable to roll off of the surfaces that the wombat wants to mark. These marsupials have a habit of pooing on top of rocks and logs to demarcate their stomping grounds, and if their scat was more rounded, it would easily topple.
