It's lovely when you smile

I read this book with my mum and is great. I was actually a bit down when I read this book and by the end both my mum and I were laughing.

This book is about a kangaroo called ROO ,who wasn't smiling. Everybody would ask him why aren't you smiling ? At breakfast time Roo and his mun fell in a muddy puddle and Roo finally smiled.
