A walk along the beach

One day, I was walking along the beach, when I heard a noise,
so small I could barely hear it. I wanted to find where it was coming from.
I followed the noise, and found myself rounding on a cracked shell.
I looked inside and could see a small creature: a clam. I didn't know what to do,
so I brought it to a nearby water pump and made a little bowl of water with an empty
piece of plastic I had found. Putting it in the water, the clam started to do something I couldn't
describe and as I watched, I saw something shiny. Wondering why I hadn't seen it before,
I picked it up out of the clam and found myself holding a pearl. I put the clam back in the ocean
where it would be safe and brought the pearl home. I studied it carefully and found that it was shinier
and prettier than any other pearl I had ever seen. I knew it had to be special.

But now, I always wonder, could this have had something to do with that odd little clam?
