Tina is a minor character, who made her first appearance in "Back Out There".
Not much is known about her, except that she is Rusty's piano teacher.
She has gray hair tied to a bun, small eyebrows, and three pairs of eyelashes. She wears a violet sweater over a white collared shirt, glasses, long dark brown skirt, and leg warmers with white shoes.
Tina likes to meet new people, and she is shown to be caring towards Rusty.
