A Crunch in the Sand

My gun barrel scraped across a hard buried cylinder half-hidden under the sand. A dead AA battery! Finally, actual food. I kicked away the damp grit, jammed my foot down to pry it loose, and bit right into the metal casing with a fierce crunch. A delicious jolt of warm, metallic acid zapped my tongue sensors. Still slightly salty from the ocean air, but superior sustenance nonetheless. Nothing else out here stood a chance.
