I apologize for the sheep incident at your farm last Friday. You see, all Earth creatures are a bit strange. These sheep were the first creatures we noticed on our scan. It's not that Kryzflitz doesn't have four-legged ruminants and fields for grazing, it does. Our ruminants (Blookas in our language) have horns, scales and webbed feet. Only the dreaded Gorg beast has a furry white coating and that coat hides six limbs with sharp claws.
So culturally, we have no equivalent of a "sheep in wolves clothing" other than fuzzy white beasts capable of ripping your hearts out and cute, adorable scaled pets we slaughter for food much like your world has lamb and mutton. We wish to assure you that the sheep did nothing to attract our attention. It would be a mistake to punish them. Dumb beasts might be capable of sarcasm but not spite. Wild Blookas can be quite rude, nasty and potty mouthed. Your sheep merely bleated twice before the, uh, accidental firing of our heat weapon.
Again, we deeply apologize for the incident and hope that some day in the future we can make up for the loss of your pet sheep.

PS. Our exhaust cooked that wild flying thing that was floating on your lake. We hope you don't cook ours.
