The Towering Wilter (S03E02)

After the entire class receives failing grades on their tests, they voice their frustration, claiming that Mr. Wilter instructed them to study Chapter 11 instead of Chapter 12. Rudy steps up, asserting he can prove Mr. Wilter wrote Chapter 11 on the board before recess ends, threatening a week without recess if he can't. In Chalkzone, Rudy discovers a trash can named Push, who has the Chapter 11 note stashed away. Push is busy constructing a tower out of all the assignments given by Mr. Wilter, and Rudy must persuade him to allow a photo of the note for evidence.
