I can wait.
Cool, I mean, it's not really a spoiler, we kinda announced this so called 'sticky goat' in the title of the book, but even so you should have seen the newest page before looking at this mind-blowing, behind-the-scenes, seldom-seen-before piece of art work.
Back when we had freshly designed these characters, when I knew very little indeed of what was going to go down in these stories, or even who the characters really were, I decided to do a couple of comic pages more to take them for a test-drive than anything else.
I am sure you have noticed by now that my characters can often stray off-model, and I thought drawing a few practice comics before we began would help me refine them a bit more before we began and help make them somewhat consistent. Unfortunately, that wasn't really the case (look at the first ten pages of The Sexy Virus, back when I was attempting to bite Joann Sfar's style a lot more).
Anyway, I just went ahead and drew three test comics - no dialogue, no story, just the characters moving around the page and interacting, really.
And one of them was this one:

And that thing, clung to the ceiling, which is really nothing more than a cute thing I scribbled, grabbed Luke's imagination.
And then this book happened.
