Tina is a girl who Lisa meets while taking private gymnastic lessons with Lugash. She is best friends with Carrie. Despite appearing to be about Lisa's age, her and Carrie 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, Tina and Carrie shun her.
Tina has shoulder-length black hair (tied back in pigtails during gymnastics) with bangs. She wears a blue collared shirt with rolled-up sleeves, blue jeans that are ripped at the left knee, and blue sandals.
