Wombats Poop Out Little Cubes
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.
