Sheldon Reyes is the best friend of Anthony Denard. It is unknown if he lives on Upper Surrey Street. Sheldon tried making some money by snow plowing, but crashed his truck on the first attempt, which he did a lot of damage in Greg's neighbourhood before his dad found out his son was using his truck even though he did not have his licence yet. He appears in Diary of a Wimpy Kid: The Meltdown.
