I'm taking a swim in the ocean, on a small beach with some rocks and other features. Just a few feet under the water, there is a space beneath a huge rock, and... something there, what is it? Kind of a long thing... I reach out and touch it, and it immediately comes to life, swims out, and approaches me. As I watch, it a long nose grows out, which then branches out with spikes. It is definitely looking at me, presenting its defenses, though not aggressively.

I get out and tell someone, to come look at the sawfish. They come and look, but it's not nearly as big as I thought. Where is was several feet long before, it is now maybe a foot and a half. Rather harmless, and just swimming around. Still a fun thing to see, though!
