I guess it has already been pointed out, but i just noticed something fun in the coloring book:

Go on page 13, the find-the-words game...
Well, turns out there are a few more words than the ones listed...
Spoiler
Show

read the first four lines, you can see the words:
FEMININE
ANDROGYNOUS
FAMILICIDE
ARROGANT


there may be more, and again other people has likely found it before me, but i wanted to post it anyway
