Greg's Grandpa

Grandpa Heffley is the lovable but clueless grandfather of Greg, Rodrick and Manny, the father of Frank Heffley,and ex-husband of Gramma Heffley. His first appearance was in Rodrick Rules, where he offered to let Greg and Rodrick stay at his boring retirement community, Leisure Towers; the experience was terrible for Greg. He was seen again in Dog Days, where he finally confessed to Frank at brunch that he ran over his dog, Nutty, enraging Frank. In The Ugly Truth, he appears at his son Gary's wedding, and the family reunion and Even babysits Rodrick and Greg as Their Gramma was on a Cruise. In Cabin Fever, he appears only in a photo, but he makes a younger appearance when his son, Frank told him about his bully, Billy Staples he came to Billy's house along with his wife, telling Mr. Staples about Billy's actions.

Personality
Grandpa Heffley is strange, unpredictable, and ignorant. He sets his TV only on the CCTV channel, which he enjoys watching, infuriating Greg as he cannot watch "real" television shows at his grandpa's retirement home. He makes a dish called watercress salad, which is an uncooked salad with vinegar and green beans. Greg and Rodrick thinks it is disgusting; their grandpa seems to not care. He loves to play a game called Gutbusters as well, and forces Greg to play; Greg always wins because his Grandpa thinks the nonsensical jokes are funny. In Ugly Truth, he is shown to smoke.
