A picture book about a pouting boy who forgets that he had decided to let his inner angry lion roar, when several neighbors engage him with tasks, games and food. I thought it was nothing special, but my niece seems to love it.
Although this book presents the idea that kindness from others defuses anger, it does so in a way that may be confusing for kids. I would only use this book for a child who tends to hold onto an irritable grumpy mood throughout the day. Even for that, though, there are better books.
