question - "scary" illustrations

Hi, can i ask you something? My friend is looking for children books with "scary" animal illustrations, especially fairy tales. She's doing a small research research on that topic. What do I mean by "scary"? For example, Wolf (or fox) eating pigs (or seven kids or Red Riding Hood or birds in Chicken Little...) or being pictured with a fat stomach. Have you seen any book of this sort? Any sort of help is appreciated. Thanks in advance.
