Ben, Tom and Lindy Potter are ordinary children. They lead ordinary
lives - until they meet the brilliant Professor Savant. He tells them
all about the Whangdoodles, the wise and magical creatures who once
lived on earth but then disappeared to another land, and were forgotten
forever.
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.
