It aired in the United States on Fox on October 24, 2021. The episode was directed by Timothy Bailey and written by Juliet Kaufman. Plot At an abandoned water park (a parody of Action Park), Bart and Lisa contract a bizarre infection, requiring treatment from steroids that cause temporary weight gain. Before they go back to school, Marge calls Lisa "chunky" with affection, which causes her to be insecure about her weight. Marge takes Lisa to the mall, shopping for back-to-school clothes to make her feel better. She later says "flattering", making the word "chunky" grow bigger in Lisa's mind. Lisa gets cranky in front of the customers and workers, so Marge takes her home. Hearing of the incident, Homer asks Lisa what is wrong and is horrified when she tells him Marge called her "chunky". He lets Patty and Selma take Lisa to the park where they describe how they no longer care what people think of them. Later, Marge apologizes to Lisa about what she said to her, but says words like "Normal" and "Perfect"
