The grass has grown very long. It is so long that when Peppa and George play outside with their plastic ball, they can’t see each other and the ball gets lost. The grass is too much for Daddy Pig’s rusty old lawnmower so he calls Grandpa Pig for help. Grandpa arrives with ‘Betsy’, his fantastic, motorised lawnmower and gets the grass cut in no time. Peppa and George find their plastic ball again and it bounces brilliantly on the short grass.
