Eric Carle knows what we know: Caterpillars are ravenous. So it's not exactly news that "The Very Hungry Caterpillar" will chow down on anything it sees, including plums, pickles, Swiss cheese and salami. Of course, the lives of caterpillars are short lived; after all, they turn into butterflies. But this hungry guy has been eating his fill since 1969.
