Pat and PC Selby plan a bowling night on the village green, Ajay and Ted both want Pat to be their bowling partner, and Sarah is upset when Lucy gets an imaginary friend.

The Village Green is covered in Dandelions. Charlie and Julian are bored and all the adults are busy doing their Saturday chores. They decide to help with the chores and get the other children involved to form 'The Saturday Club'. The children split into groups to do various jobs. However, something keeps destroying all their efforts.

In each place they find sheep's wool and Pat and the Children go to Thompson farm to investigate. Meanwhile, P.C. Selby and Ajay hold a stakeout at the Primary school as it has not yet been attacked.

The sheep have been escaping and Alf Thompson and the others then round up them up. They are then put to work on the Village green to remove all the Dandelions.
