Today the Earth met aliens from outer space, who landed in major cities across the globe. They don’t look like us; instead they look like human-size carrots, artichokes, broccoli and other familiar vegetables but with faces and little arms & legs. Friendly, exploring visitors finally coming to greet us from a different galaxy.
At least that was what we thought. Then we discovered these big space vegetables eat people, just the reverse of us. So is this now-invasion just revenge for their consumed Earthly relatives, maybe?
