The Twirlywoos are in a park, where they watch a girl on rollerskates with her dad. She takes off the skates but accidentally kicks one so that it rolls away down a hill. The girl and her father take off in pursuit of the runaway skate, leaving the other one. Toodloo jumps on it and rolls away down the hill. The other Twirlywoos follow Toodloo down paths and steps and skate ramps until the skate comes to rest on top of a slide in a playground. Toodloo's enthusiastic waving to the others (who are at the bottom of the slide) causes the skate to tip and hurtle down the slide. Toodloo crashes into the other Twirlywoos, and the skate continues on its journey, only to be reunited with the girl and her dad! The Twirlywoos return to the Boat to discover the Twirlywoo Screen. A series of sloping lines appear, followed by a marble. When Toodloo reaches up and touches the marble, it starts to roll down the course until it drops onto the floor of the Boat. More and more marbles draw on and roll down until the wall is full of rolling marbles which all fall down and roll away into Peekaboo's house.
