BFFs Gerald and Piggie (I Am Invited to a Party! and There Is a Bird on Your Head!, rev. 1/08) are back in their fifth and sixth easy-reader episodes. The pair's friendship is put to the test in My New Toy when elephant Gerald accidentally breaks Piggie's prized possession. Their spat follows a familiar arc: anger and sadness, tears and regret; all ends well, thanks to a squirrel's intervention, and the two conclude: "Friends are more fun than toys." In the companion volume, Piggie and Gerald watch as a squirrel surprises an unsuspecting pal; it looks like fun, so they give it a go. The game doesn't work too well, however, if both players lie in wait for each other. While Gerald panics-"Where is Piggie?...Maybe a giant bird...flew off with her!"-Piggie gets sidetracked ("I am hungry for lunch"); their silly overreactions are classic-cartoon funny. The simple speech-balloon text uses a fair amount of repetition to encourage new readers, and Willems skillfully conveys mood and tone through type size and his characters' expressive body language. This series' broadly sketched, satisfying dramas are just right for readers beginning to venture out on their own. Horn Book" Gender: unisex.
