Nasty Pants
"You smell like a dirty diaper. P.U.!"
-Nasty Pants, on Greg Heffley and Rowley Jefferson .
Nasty Pants is a kindergartener in Diary of a Wimpy Kid: Cabin Fever who used to frighten Greg and Rowley after they departed from school. To avoid being terrorized by Nasty, the kids went around Nasty's house. Eventually, the boys' fathers complained to Nasty's mother, but she said that Nasty gets wounded up sometimes. It is unknown what happened to him afterwards.
