Does Anyone Know What a Crile Is?

This week I was cheeking over Elijah's school. He was suppose to write a rhyming word for a list of words. One word on that list was "SMILE". The word next to it was "CRILE". I had no idea what that was, so I asked Elijah what a "crile" was. He looked at me with a straight face and said "You know Mom! An alien car." Hmmm, I wonder what dictionary he is reading out of... ;-)
