I actually sketched this strip out twice. The last one didn't include the last three panels. I put them back in to add more suspense. I keep forgetting that Squeaky doesn't think like Bob and Merlin do. Because I started writing "Hmm, a brick wall" in the first panel. In fact, you can kind of see the white-out if you click on the strip.
Squeaky is a Secret Friend, but I had him interact with Merlin in this strip. Why? "Secret friend" doesn't mean "Only one person knows I exist." In my strip, it means "I am known to the outside world, but only one person is a friend with me, and no one knows the last fact but me and the one person I just mentioned."
You know, I don't think that came out right.
