Grade 1-4-Twenty-six mammal skulls from anteater to zebra are highlighted. Readers can see each skull, but are not told immediately to which animal it belongs. In some cases the features of the skull itself give it away, as in elephant or ram. Other times, Pallotta gives verbal clues: "A sly person can identify this skull-there are only three letters in its name" points to fox. There are also visual hints such as the mousetrap next to the cat skull and the bananas upon which the monkey skull rests. Others, such as baboon and gorilla, are particularly tough. On a spread between V and W the names of each animal featured in the alphabet are hidden among drawings of non-mammal skulls. In addition to the clues, the author works in scattered facts about skulls in general and about the individual animals.
