Percy has been working at the coal mines for several weeks and is fed up with the work. Toby and Bertie try to cheer him up, to no avail. Then one day, Percy is pulling some trucks up to the yard, when they break away. Percy and Bertie chase after them and workmen manage to put chocks under the trucks' wheels after they slow down going up a hill. After that, Percy decides that one should never be taken by surprise.
