Mr. Nuzzi is a prison guard who appeared in Diary of a Wimpy Kid: Old School . He attends the field trip to Hardscrabble Farms as a chaperone and gets put with most of the troublemaking kids due to his job. He is seen confiscating a chocolate chip cookie that Duane Higgins tried to smuggle in. Greg foils his plan by having each one of his cabin-mates step into Mr. Nuzzi's footprints by using the chapter from The Essential Book For Young Lads called Hiding Your Numbers. That way it will look like the baby powder has been untouched. On their return, however, they accidentally trample it.
