Horrid Henry isn’t always horrid. Did you know that? Sometimes he tries hard but someone still comes along to out-do him. Like goody two shoes Perfect Peter. With Mothers’ Day around the corner, Horrid Henry is determined to up his game, shame his brother and show he’s the best son. Yeah, I know. Even when he’s trying to be nice he’s being a little horrid, really, but still. It’s the thought that counts.
