When the eggs hatched, the crocodiles crawled to the riverbank. But Cornelius stood up and was the only one who walked upright on his hind legs...

The value of difference, understanding and respect for those who do not act according to established conventions, in addition to the effort required for learning, are reflected in this classic of children's literature.
