Story : When the entire class gets F's on their tests, they complain that Mr. Wilter told them to study Chapter 11, not Chapter 12. Rudy then tells Mr. Wilter that he can prove that Wilter wrote Ch. 11 on the board before recess is over or there would be no recess for a week for the students. In Chalkzone, he finds out that a trash can named Push has the Chapter 11 note from the board. Push is building a tower of all the assignments Mr. Wilter gives. Rudy has to try to convince Push to let Rudy take a picture of it to show Mr. Wilter.
