The front cover image of the Catterwhip is an edited version of the character reveal from the book. I removed the loaf of blapper and the Wishangrope. The Catterwhip is a near literal cat-o-nine-tails (though I gave her only 8). My approach to illustration the book was to latch onto familiar elements within the invented words. My original Catterwhip sketch was a little more scary. I kept the essential elements, but toned things down a little.
