Beached Weirdos #1

Is this a simple case of finders keepers, or is there nefariousness involved?  Is "nefariousness" even a word?  The dude inside the truck may have the answers, but he is mysteriously silent on the subject.  The mermaid's not answering any questions, either.  So I guess we're just left with guesses and assumptions.
