The Twirlywoos are in a field with an obstacle course. They watch an athlete going over the hurdles and decide to try going over them themselves. As the hurdles get bigger, going over gets harder and harder. Great BigHoo gets stuck at the top of a rope hurdle, but his misfortune helps the athlete out! On the Big Red Boat the Twirly Rings are going over and over the Twirlywoos - but where will they land?
