Gammie Heffley is Greg's great grandmother and the head of the Heffley family. She has only appeared in The Ugly Truth, but had a major role as the main antagonist, taking a place Rowley was rumored to fill. Also, one time she thought she had won a lottery scratch ticket, but it turned out you needed to match 3 fruits to win. Also, she gives everybody a lecture called "the Talk". All of the furniture in her house is old and valuable, and people have already started claiming some of it for when Gammie dies. Gammie also gives advice to Greg about growing up.
