 A trip to the zoo is off to a bad start when Roland can t fit through the turnstiles. Even Miss Mooney is finding the loud teacher from a rival boys  school hard to bear. Annette chats up Carrots Garvey, a pupil of Westerfield School, and a friendly little war breaks out. A polar bear seems to enjoy Zammo s lunch, thrown by  Carrots , and Zammo s told off for feeding the animals. Annette gets  Carrots  into trouble, by pretending to be stuck on a dinosaur statue, but she is dismayed when he is walloped for his gallantry. After a fight, Jonah loses his satchel - but hang on, there it is inside the sea lion enclosure! He won t listen to reason, and goes in to fetch it - all would have been okay, if a keeper hadn t shouted at him, and he falls into the water. Jonah and Zammo escape onto the ghost train of the adjacent fair. Janet ("Row-land") St. Clair begins her nagging campaign against Roland, which she will continue to do for years to come! Zammo tries to get Jonah dry, but it s an uphill struggle. Carrots Garvey is smitten, and wants Annette s name and address, but she gives a fake name. Finally it s time to go home: Roland is missing, and Mr. Sutcliffe has to have a little heart-to-heart to bring him back.
