Heather Hills is Holly Hills' older sister who appeared in Rodrick Rules and Dog Days. She is in Rodrick’s grade, whom Greg has a crush on. She is also alphabetically put after him. She was once Rowley's baby-sitter until Rowley's parents switched her with Leland. Apparently, she is in the same grade as Rodrick, with her yearbook picture being next to his in their sophomore year. Rodrick always tries to make it to Rowley's house with Greg before storytime when Heather babysits. Rodrick is surprised when Rowley's parents replaced her with Leland. In Dog Days, she works as a lifeguard at the country club, and in the film Rodrick tries to get her to save him from drowning but some other man sees what is going on, saves him and gives him the kiss of life while Heather is talking not very nicly to a little girl. This sends Rodrick in tears, partly because his FAKE tattoo is ruined. This makes Greg very embarrassed because his best friend Rowley Jefferson and Crush Holly Hills are there as well . He says that "besides, those long-distance relationships never work anyway”.
