High tide had been reached, and the water swelled onto shore. I looked towards the harbor, where the water was calm and quiet. A seal bobbed its head by the rocks below.

I could tell it wasn't a seal, but it wasn't a dolphin or a sea lion either. It was dark and light at the same time, sprawled out in the water. The current was pushing it towards me, and I nearly jumped out of my skin when I realized it was a person..."
