1ZIP IS BACK, AND HE HAS A NEW BUTTON! Zip is eager to show off his new button to Cat, even though he isn't quite sure what it does. Will it take them back in time? Send them to the moon? Make them invisible? It turns out the button has a much more practical and relaxing purpose. This beginner reader book, with bold, bright illustrations and simple text, also makes a sweet bedtime story! Printed as a board book, the story is nicely designed for children and readers of all ages!
