Postman Pat and the Greendale Knights

S5, E4: Pat gives the garden a makeover whilst Sara, Dorothy and Nisha have a girl's day out. He babysits the various kids who are all busy playing knights in armour. Bill teases Lucy for being "girly" and not wanting to play knights properly. Pat builds the kids a castle out of old boxes which they play in, leaving Lucy outside as castle guard. To Lucy's horror a strange knight arrives in a metal helmet with a glowing sword in his hand. Lucy bravely confronts her fear and douses the "knight" with water from a hosepipe. It turns out to be Ted in his soldering gear who has come to fix the rose arbour for Pat's garden makeover! As the mother's arrive home they are confronted by a beautiful garden. Sara knights brave Lucy for defending the castle. Pat tells Lucy that they're both knights in shining armour now!
