"Don't Be Horrid Henry" is a book written by Francesca Simon. The book is aimed at a younger audience, unlike the other Horrid Henry books. It was also the only book to be illustrated by Kevin McAleenan.


It's a dreadful shock for Horrid Henry when Perfect Peter is born, and despite his best - or worst - efforts, he can't manage to get rid of him. As Peter gets bigger, Henry gets crosser. But the day comes when Henry inadvertently finds himself saving Peter from a fierce dog and discovers that it's rather nice to be a hero.

  • Mum's hair is brown and Dad's hair is blonde in this book, but they are the opposite way round in the actual stories.
