This sidesplitting chapter book in Newbery Honor–winning and bestselling author Louis Sachar’s Marvin Redpost series takes on rumors and teasing.
 
There’s a rumor at school that Marvin Redpost picks his nose. Clarence started it, and now everyone believes it. Even Marvin’s friends are embarrassed to be seen with him! Can Marvin figure out how to change everyone’s mind? Or is he doomed to be teased...

A small incident during recess threatens to turn nine-year-old Marvin into the outcast of his third-grade class.

Even though they have all come to school in holey clothes, Marvin and his third grade class manage to impress their surprise visitor--the President of the United States.

Two days after Marvin sees a glowing green thing like a flying birthday cake in the night sky, his third-grade class is joined by a mysterious new boy with peculiar behavior.

After Casey Happleton tells him that if he kisses his elbow he will turn into a girl, nine-year-old Marvin experiments and finds himself very confused about his identity.
