Rodrick Rules (film)
She was first seen entering church with her Mr. Hills and Holly. She was next seen horrified when she saw chocolate (which she thought was poop) on Greg Heffley pants. She then screamed when he licked it to prove it was chocolate. She was last seen attending the talent show with Holly and Mr. Hills.
The Last Straw
Greg Heffley tried to call Holly but Susan Heffley picked up the phone and was on the phone with Mrs. Hills. It took them a few seconds to realize what happened and chatted like nothing happened.
Dog Days (film)
She was seen at Heather's party. She was surprised when the band, Loaded Diper, starting singing "Baby." She was horrified when the angered Heather attempted to kill Rodrick but ended up hitting the chocolate fountain, splattering chocolate all over her and her friend.
