Holly Hills is a girl Greg had a crush on. She is the most popular girl in Greg's grade and as Greg says "is the fourth prettiest girl in my class but the top three all have boyfriends." Greg tried to get a good moment with her at the Valentine's Day dance, but Fregley ruined it because of a huge sugar rush after he ate a bunch of cupcakes from the refreshments table. At the end of Book 3, Greg gave up on girls because she mistook him for Fregley. It might be hard to see but she might like Greg. Her name on the visual novel was Piper Matthews.
