Principal Sternblast is up to his old tricks, but what is he plotting this time? We need to find out before it's too late. Can the new students help? Was that a croak I heard from behind the canteen? Yes, but what does that have to do with anything? Mr Bambuckle and the class in room 12B welcome four new students following the closure of the local grammar school. Will they all join forces in time to save Blue Valley School?
