Bink Says Boo

$$ Bink Says Boo is a book intended for small children who are just learning how to read. Since this book is a reading group option in Greg's school in Diary of a Wimpy Kid, one can assume that some of the students are illeterate or have special needs with reading.

Appearance
The cover is drawn by Greg and is black and white. The cover reads "Bink Says BOO." There is a short, chubby, little boy on the cover with four little hair and striped shirt, assumed to be Bink, who says "boo."
