Fat Albert and the Cosby Kids (1972) : 7x1

Rosita is a shy Mexican-American girl in the gang's class. Rudy ridicules her for her halting English, prompting her to miss class for a couple of days. When Fat Albert tries to intervene, they're interrupted when a fellow Hispanic has an emergency kitchen fire. With quick thinking and communication, they're able to put out the fire with little damage. Back at school, Miss Wucher assigns a project for the kids aimed at illustrating that they all have a heritage of which to be proud. Rosita is surprised the gang know of famous Mexican figures in history after returning to class and interacting with the gang again, eventually getting the last laugh on Rudy.
