Pat calls at the post office to collect a registered letter to the camp site, and a parcel for Granny Dryden. Pat has to help Peter Fogg get some wandering sheep out of Mr. Jackson's Garden, then he delivers Granny Dryden's parcel and asks her to get a new digital watch, then he deliver some eggs and a registered letter to some campers.The letter is too valuable to leave and the campers are at the waterfall. Pat's van can't travel the bumpy road so Miss Hubbard borrows a tractor and takes him on a rather bumpy ride to the waterfall. When Pat returns to his van, he sees that a hen has got in and laid an egg.
