It's Wiggy Pig's birthday, and the guests come one at a time to be counted. The characters include a wide variety of animals, from pigs and mice, to dinosaurs and dragons. The plot starts out as the problem that Wiggy Pig is by himself on his birthday, and grows as more and more people show up for his party. It is set in Wiggy Pig's house, but no specific time or place is established. The illustrations build the theme by constantly providing opportunities to count objects in the background and party guests on each page. The style is poetic and simple, and keeps the story light and happy. ( )
