Carrie is a girl who Lisa meets while taking private gymnastic lessons with Lugash. She is best friends with Tina. Despite appearing to be about Lisa's age, her and Tina are actually college students--they explain that because of their petite gymnast builds, people often mistake them for being younger than they actually are. Lisa pretends to be in college too in order to impress them. After finding out that Lisa's still just an elementary school student, Carrie and Tina shun her.
