You were just strolling around, taking a hike, and on the shore of a bay you see a 27 foot long, 4 foot tall creature with the body of a beluga whale yet the legs and osteoderms of a crocodile. It's fully aware of your presence, yet It's just sunbathing for now, the only reason it won't attack you is because it's not hungry, it won't give up the perfect sunbathing spot, and you don't appear as a threat to it.
