Okay, first of all–could it be possible that to this alien (who may or may not be purple himself) we appear to be…purple? Some alien genetic thing?
Secondly, and mostly just out of personal curiousity,
This flag, is it…purple?
Yeah. On the other hand, those one-eyed, one-horned people eating flying creatures are pretty common!
I say the OEOHFPPE eats purple people.
