Abrams Appleseed sent me a copy of this book to read for review (thank you). It has been published so you can get a copy now.
This is a bit like the word games where they give you several words and say, "Which one doesn't fit?"
Monsters don't act like humans. They don't eat the same things (obviously) and you spend your time snickering while you watch what they do choose.
My very favorite was what they took baths with. They take baths with chocolate pudding! Can you imagine?
The whole book has fun ideas and contrasts that your children will think are silly and funny. Just tell them not to try any of them at home...
