Evil Fish

I picked up a grade 3 boy from art today.  Incidentally, this was my first ever case of me asking for a particular child, and the teacher responding with "Yes!  ...good luck..."

Me: What were you working on in art?
Boy: We're painting schools of fishes, and they all have to swim that way [arms point to the right].  So I asked Mrs C if we could have an evil fish going that way [one index finger points to the left].
Me: What did she say?
Boy: Well, she said it was okay to have a fish swimming that way [left]... but not an evil fish.
Me: Okay... How would you paint an evil fish, anyway?
Boy [like, duh]: With its eyebrows pointing down.  And all the other fish are blue, but the evil fish is red.

So, beware red fish.
