So there's a digital strip called the Numbskulls about a little boy with weird characters inside his head who control him and his actions. Kids will obviously love it, and we got asked to do our own Numbskulls.
Initially I thought of a demented Hannibal Lector type living in my head as the leader of my Numbskulls, but was reminded this was for kids. Still I wanted a villain type...and that's when I remembered Mojo Jojo.
I think he's still a bit too scary for chilluns.
