When ur swimming and something touch ur feet

Is that Fiona?

There was a glacial lake that I would go to a lot as a kid, and though the water was deep it was also really clear and relatively undisturbed. Anyway, there was a huge skeleton at the bottom among plants and we'd all be afraid to swim over it because it might touch our feet. There was a legend that it could move and bite you. Whenever a stick touched our skin, we'd scream because we thought it was the skeleton.
