A dramatization of Pierre Berton's adventure fiction for children. "In this fantasy adventure four children: Penny, the leader; Pamela, her common-sense sister; Peter, whose life's ambition is to become a garbage man; and Patsy, who collects frogs in her pockets, set out in search of their baby brother, Paul, better known as 'The Pollywog,' who has vanished mysteriously from their playhouse. Accompanied by their fearless pets, the children descend through a secret trap door into a strange underground world of mushrooms, whose green inhabitants know only one word: 'OG.'"
