The Annual School Party is being held and everyone is getting ready.

P.C. Selby is going to the dance with Doctor Gilbertson, however he needs to help Alf Thompson with his sheep and his car breaks down on the way to her house. He eventually makes it to the party and the Doctor forgives him.

Lucy Selby is trying to find a costume but is unable to find anything suitable. However, Pat and Sara help her to make one and Pat gives her a chauffeur ride in Doctor Gilbertson's car.

Pat's shoes and socks get wet when he steps in a puddle at Ted's Workshop. Ted has invented a sock drying machine. However it, unfortunately, destroys Pats socks.

As a result Pat has to borrow a pair of pink fluffy rabbit slippers, which he wears for the rest of the day.

The children are on a field trip to find five different types of fruit and vegetable.

Ted follows Pat with his improved machine until he gets to the Primary School. When he arrives Jess knocks the fruit into the sock-drying machine, which turns out to be a perfect juice-maker.
