Bob and Flo - the missing Bucket

Flo, a little penguin, arrives at nursery with her packed lunch: a new pink bucket of shiny fish. Bob is fascinated by Flo's bucket and he puts it on his head! Then he uses it to make sandcastles, to reach the top of his block tower, as a drum-kit. In fact he's so creative in how he uses Flo's bucket that it takes her some time to track it down. But when she does the bucket becomes more useful than it's been all day - it becomes the object that brings Bob and Flo together as the best of friends! 

With so much of the mystery of Flo’s missing bucket being told through the charmingly simple illustrations, it’s very much a case of showing not telling. A perfect lesson of the power of pictures and indeed picture books, and their vital importance in the journey to true literacy.
