Do you believe that a dolphin can transform itself into a man?

When we were still small, there was a sail boat here. My father also had one which was called "Nega". It always lie there on the shore.

One day, my mother sent me to a neighbour, a Mrs Filuca. The path led me past the boat's mooring place. When my friend and I were approximately twenty to thirty metres away from the canoe, we saw a creature in the bow of the canoe, which looked like a man. We approached it, without any fear. Suddenly the "man" sprang into the water and floated. And there we could see that it was a dolphin. My friend ran away in fear and shortly afterwards the dolphin also disappeared.
