Yellow Bird found a button and can’t wait to show Red Bird and Blue Bird. When they ask him what it does he tells them, “Nothing” but they want to push the button themselves. When they do, they find out that the button does more than nothing, it does everything! This book is sure to delight any fans of Elephant and Piggie. The illustrations are simple and bright and the text is humorous but also offers a chance for understanding emotions. Blue Bird is surprised, when Red Bird doesn’t get surprised he gets sad. They exclaim that the button does something but, when Yellow Bird insists that the button does nothing he gets mad.
