Why wombats would represent nuisance?

Oh, dude, wombats could be considered a nuisance because they have a tendency to dig extensive burrow systems that can damage fences and roads. Plus, their poop is cube-shaped, which can be pretty annoying to clean up if you accidentally step on it. So, yeah, if you're not into unexpected landscaping and geometrically interesting feces, wombats might not be your favorite neighbors.
