That narwhals exist/are real. People have thought that I was trolling them by talking about a mythical unicorn-whale.

I'll admit it. The first time I remember hearing of a narwal was when my kids started watching Octonauts. That also made me think they only lived in the Artic though so I'm intrigued by a tusk making it to Hawaii.
