Oobi and Uma are at the playground. Oobi asks Uma if she wants to play on the seesaw, but Uma would rather spend the day on the swings. Before she swings, Oobi shows her how to swing carefully. Uma gets impatient and ignores what Oobi says. She tries to swing as fast as she can, but loses her balance and falls off. She starts to cry, and Grampu rushes over to see what the commotion is. Luckily, Uma is okay, but she's just scared. She feels better after Grampu comforts her, but she's developed a fear of the swing set.
As soon as Grampu leaves, Oobi asks Uma if she wants to try swinging again, but she says no and calls the swing a bad swing. Oobi tries to calm her down by playing on the slide, making sure that she doesn't hurt herself again. They slide down together at first. Then, they take turns sliding alone. On his turn, Oobi decides to twirl around and falls off. He doesn't get hurt, but this reminds him that it's very important to be careful. Oobi asks Uma if she has the courage to try swinging again. She tells him that she'll try, this time listening to Oobi's advice.
Uma swings carefully and is astonished to be swinging all by herself. She calls Kako and Grampu to watch. After she finishes swinging, Oobi plays a counting game with the other characters. Uma wants to play another game and suggests giving each other piggyback rides. Everyone piggybacks on top of each other, but they lose their balance and fall down, laughing. The episode ends.
