Nasty Pants

"You smell like a dirty diaper. P.U.!"

-Nasty Pants, on Greg Heffley and Rowley Jefferson .

Nasty Pants is a 5-year old who used to frighten Greg and Rowley after they departed from school. He only appeared in Diary of a Wimpy Kid: Cabin Fever. To avoid being terrorized by Nasty, the kids went around Nasty's house. Eventually, the boys complained to their fathers about it, so they complained to Nasty's mother, but she said that Nasty gets wounded up sometimes because he's only 5.
