"Clap Hands!" is an episode of Oobi.
Oobi and Kako are clapping their palms together to pass time. Uma sees them and asks if she can join, despite never having played a hand-clapping game before. When she and Oobi try to clap their palms together, they swerve in opposite directions and miss each other. They try again with no success. Kako decides to help by teaching Uma how to play. He and Oobi clap together once again, this time letting Uma see how they do it. Uma tries to clap with Oobi again and succeeds. Oobi and Kako cheer for Uma and give her a round of applause. An audience cheers from off screen and Uma bows triumphantly.
