I don't know if you can make out my writing as it is a bit crazy but I tested it on my hubby (who didn't think the book was in the least bit funny, something about good literature hehe) and he could read it. The text is supposed to be in a brain (pathetically drawn I know) and the zombie is biting it (hmm hilarious, not really haha). I drew the zombie and brain on rymans card and coloured it with promarkers and copics and used a copic pen to do the writing. (I used to do this writing when I was younger and had a few people ask me to do them their names for their doors).
Anyways here is a close up of the text:
