The shortest kid in the second grade, James Moody, also known as Stink, learns all about the shortest president of the United States, James Madison, when they celebrate Presidents' Day at school.

Seven-year-old Stink Moody, having discovered that he can get free samples by writing letters of complaint to companies, gets so caught up in his letter writing campaign that he misses his best friend's birthday, but he plans a super surprise to make up for his mistake.

Stink and his friends try to earn money to buy the latest book in the Nightmare on Zombie Street series and go to the book release party.
