Some creatures get a regrettable reputation through no fault of their own. Sharks are actually vital to the ecosystem. Wolves have complex and loving pack cultures. My cousin Fred is actually a really nice guy despite his weird hair thing. But then there's these guys: Kappas. They are unapologetically mythical humanoid turtle monkey water-dwellers who like cucumbers and sumo wrestling and eating people. And no amount of PR is going to change that.
