Interesting that indeed wombats poop square shaped pellets. They are practically blind and use their scent to find each other (no wonder Binky doesn’t bathe) so their square poop won’t fall off the log or other areas they drop it. And because they don’t process the vegetation they eat very well, someone decided they would make a good source of paper fiber.
For those who don’t recognize the glass wearing animal in the lower right, that is Binky a Wombie from Peter Marinacci’s webcomic Wombania. He says that wombies are genetically altered more intelligent wombats. Whenever Peter posts a cartoon with Binky I tend to act like I don’t like him. And Binky returns the favor if you have ever read the comments on my posts.
So yes. The first ugly cousin of the cute koala are wombats/wombies. Well really just Binky (the rest of the wombies are cute).
