Role in The Last Straw

In the Valentine's Day Dance, she told every student that the dance would count 20% of their Phys Ed grades and went with Mr. Underwood noting down the marks.

Role in Cabin Fever

She is briefly mentioned when Mrs. Lahey threatened Leon Goodson and the other kids to spill their Rowdy Riots or she will report them to her.

Role in The Third Wheel

She is mentioned by Greg when she announced that there is a limit of toilet papers the kids can bring and only 5 are allowed.



  • It's implied that she's friends with Mrs. Heffley, because in the first book of the series, Greg claims that his mother is "really tight" with the principal, and figures that she did some string-pulling to have him put in the advanced reading group (after trying but failing to get put in the easy group).
