Dr. Pierce McWiggle scratched a writhing tenticle across his brow and tasted some of the charred honeydew melon.

"Interesting." 

Honeydew melon does not grow on this planet, though several varieties of vegetable and one animal are somewhat similar.  None of them travel at very high velocities, and few get charred on their own.

"Fruit may be extraterrestrial in orgin."  He jotted down with a serpentine finger a few more notes, and then got to work.

Dr. McWiggle consumed the entire Corpus Delicti with gusto and vinegar, and carefully filed away the report.
