Mom is worried that Gumball isn't getting enough attention at home, so she follows him to school. Gumball and Darwin are extremely embarrassed, especially when she calls Gumball "Gummypuss" in front of the other kids. When Mom meddles in his romantic life by asking out Penny for him, Gumball loses it and denies that he has any feeling for Penny. In order to win back a broken-hearted Penny, Gumball decides to impress her by dressing up as a cheerleader and defeating her in the cheerleading competition. After a spectacularly lame performance, Mom is there to pick up the pieces.
