You thought it would be funny to stow away on a submarine, with mixed results. On the one hand, your new captors are a crew of mermaids who bear an endless series of hilarious indignities aboard this sub designed for humans. Chief among these: they must flop and drag themselves around to move, like fish out of water. They seem quite used to it, but it's still quite funny to you. The bad news is they bet you're a spy. Can you negotiate for your freedom, or at least your safety on this busy sub?
