'Leapfrog' is a series of first reading-books for new readers and older more reluctant readers. The stories are presented using large-format text with bright, full-colour illustrations to aid the newer, or first reader. In this story, Sam is disappointed when he gets chickenpox and has to cancel his birthday party.
