It's more than a book--it's a game! Every spread is missing a key element of a featured animal--from an elephant's trunk to a penguin's beak, these creatures are incomplete. And it's up to young readers to help them out! Kids can finish the illustration by wiggling their fingers through suitably placed die-cuts. Children are sure to giggle at the silliness of turning their fingers into elephant trunks and chameleon tongues--and learn a bit about animal features on the way!
