Julie, Horrid Henry's mum, is a well-meaning but often exasperated parent. Her hobbies include gardening and baking, which she finds relaxing and fulfilling. Julie seems to favor her younger son, Peter, who is more obedient and less troublesome compared to Henry. This favoritism sometimes causes tension with Henry, who feels overlooked and misunderstood. Julie's relationship with her husband, Simon, is generally supportive, though they occasionally clash over parenting styles.
