One day, Ms Mobbs takes her 2M class of students on an eventful excursion to see the park, a building site, and old tram and the Art Gallery. They leave school in an orderly line, all neatly dressed and wearing hats and backpacks. But things go wrong from the moment Jason's dog insists on coming too.
All children (and all teachers) will identify with this wonderfully funny saga of loss, disaster, drenched clothes and squashed lunch-boxes.
