I would like to recommend you the JP book "Big Chickens" by Leslie Helakoski, illustrated by Henry Cole.
Cole's bright and colourful chickens on the cover is simply charming. The chickens' facial expression is realistic yet hilariously funny. The artwork runs in tandem with the plot and captures the silliness of the characters.
As I turned the pages, you was intrigued by the power of fear. Yet with all the hilarious happenings, I soon realised that we can find courage from humour and humour can be more powerful than fear.
Helakoski used repetitions, questions and rhyming action words to tell of all the sly, silly humour. He had put them together so cleverly and fluently that I just wanted to read on after the first two pages.
It is definitely a good book for story time.
