Mostly just a smattering of nonsense and sketches that went into character development. I was fairly well surrounded by boys growing up - Rocky and Freckle seem to naturally conjure childhood memories of that boyish dynamic I became familiar with and all the destructiveness that went along with it. So often the only explanation for ritual torture amounted to 'because.' That's tiddlywinks Freckle is playing at the bottom. It just seemed like the sort of thing that would amuse him.
