This is a pretty short book and would probably be an accompaniment to a bed time story rather than the main story itself.
It consists of a series of bar code like images, and when you turn a page a tab inside is pulled to make an animated image. The first few times you look at this book you won't be able to stop yourself from turning the pages quickly and slowly to perfect the speed of the animation!
It is a novelty - and thankfully a pretty tough one! Unlike books which contain pull down tabs which can easily bend and tear, the pages are thick and the tab to action the action (as it were) is internal to the 2-ply tick card pages so it can't be broken.
Like the other reviewer, I also like the monkey swinging through the trees!
