A message from Zed

I got my first note from Zed the other day. He's one of my little boys and is four years old.
I'm sure that I could spend many an hour psychoanalyzing it. For instance, why is it inside a cartouche? I presume it is our family, so who is the extra person? Rowan must be the spider-like person with the long hair, does that make me the one at the bottom with a Ming the Merciless moustache? Is zed the smiling one at the top, the one with no nose or the one that looks like a halloween pumpkin?
Way too much there to think about. Thanks Zed...
