The Twirlywoos are at a show-jumping centre, where they hide behind a fence and witness a horse and rider practicing going over a jump. They are interested in the idea of going over, so they decide to jump over the fence that they are hiding behind. Toodloo makes it over with ease, while Great BigHoo struggles, and Chickedy and Chick are just too small. Great BigHoo decides to help them by picking them up and throwing them. Unfortunately Great BigHoo throws them too hard and they go flying up in the air - and land behind the rider on the back of the horse's saddle! As Great BigHoo and Toodloo look on, Chickedy and Chick ride around the course and go the jumps, until the Hooter calls the Twirlywoos home. While the Twirlywoos are away, unusually, there's a knock at the door! Peekaboo goes to investigate. It's the Stop-Go Car, who is playing a jumping game. Peekaboo joins in and jumps over the car, and the two jump over each other all around the Boat, until they get back to the doors and the car drives away. The Twirlywoos return, and Peekaboo is on the wrong side of the Boat but jumps over their heads to avoid being seen and get safely back to the hole in the wall.
