Gerald is careful. Piggie is not. Piggie cannot help smiling. Gerald can. Gerald worries so that Piggie does not have to.
Gerald and Piggie are best friends.
Happy Pig Day!. Willems, Mo (Author), Willems, Mo (Illustrator) Hooray, it's Happy Pig Day! Of course, Gerald the elephant has no clue what this means, so Piggie launches into the holiday's myriad glories. The parties! The dances! The pig foods! The pig games! Everyone crying "Oinky! Oink! Oink!" (That's "Happy Pig Day" in Pig.) But while Piggie cavorts with other pigs, Gerald slinks away, feeling, as many kids sometimes do, the exclusion of not being involved in a particular holiday. Here Willems displays his cunning use of white space: the two friends are so far apart on the page. The good news? Happy Pig Day is for those who love pigs, too. - Daniel Kraus Booklist"
