My favorite part of the book was when Zack grew pointy ears and whiskers because it was funny and weird. The illustrator did not use any colors. I wish that the pictures were done in color. He only used black and white because he wanted to make the book scary. If I could change into an animal I would like to be a dog because it is my favorite animal.
I recommend this book to readers and audiences that like scary stuff. Other readers would like this book because Zack grew ears and whiskers and they will think that is cool. I would read the other books in the Zak Files series because I think Zack is funny and other readers will think he's funny too.
