Perfect Peter is a character from the popular children's book series Horrid Henry, created by author Francesca Simon. He is depicted as the ideal child, always polite, well-behaved, and eager to please adults. His perfection often contrasts sharply with his mischievous brother, Horrid Henry, who frequently gets into trouble. Peter is known for his love of cleanliness and order, often taking pride in his achievements and good behavior. He enjoys activities that are considered proper, such as reading and helping around the house. This makes him a favorite among parents, but it also leads to jealousy and rivalry with his more rebellious sibling.
