Popular kids presenter Suzy Cato presented this preschool science series. In this episode, Lucy the Friesian cow helps Cato explain how a paddock full of grass transforms into a carton of milk. Cato gathers a few "reckons" from young viewers as to how grass turns into milk. Then she dips into her prop bag of buckets, hoops, cartons and balloons, to show how a cow's digestive system works. Cato introduces biological names and terms easily and naturally, and throws in a few "cheesy" jokes to entertain.
