You can't use this Flash person as a reference when I've never heard of them, that doesn't work.

[(sorry for the unintentional burn there, Mr. Flash)]

Also, I suddenly have very real doubts that you know how turtles work. "Careening" isn't a word meant to be in their vocabulary. I mean, a bone's a rather solid thing, but we don't go throwing people into buildings when we can help it, do we?
