Mac and Bob - the Unexpected Visitor

It's a bright, sunny morning down on the farm. Mac and Bob have a busy day ahead - feeding the animals, pulling up carrots and ploughing the field on Mac's big red tractor. Suddenly, a wonderful sight comes into view. Marching bands, acrobats and lots of colourful clowns...It looks like the circus is in town! Mac and Bob love the circus. First, there are jobs to be done. But what's this? All the animals are excited, running around with amazing tales to tell. There's something unusual going on at the farm today and Mac and Bob are about to find out what it is.
