Except by Professor Savant and the three children, who are determined to visit Whangdoodleland, where the last of the really great Whangdoodles rules over his kingdom of fantastic creatures. Getting there isn't easy. The children must look "beyond" the ordinary, and see things in a completely different way. It's hard and dangerous work, and sometimes it seems that they'll never reach the Whangdoodle's castle. But little by little the children learn that with a bit of imagination, "anything" is possible.
