"Follow the Leader!" is one of the Oobi shorts.
Oobi, Uma, and Kako are playing a game of follow the leader. Oobi is the leader and makes a pose that the others have to copy. He stands proud and looks upward. Kako does the same thing, but Uma can't get the move quite right and turns the wrong way. Kako helps her figure it out, and they move to the next pose: spreading out their fingers like a spider.
Oobi and Kako do it the same way, but Uma still turns the wrong way. Kako helps her out again, and they move to the final pose: a thumbs-up. Uma does a thumbs-down, so the boys flip her right side up. Oobi and Kako decide that Uma should be the leader next so she can make up her own moves. She decides to dance around and twirl her index finger. Oobi and Kako are a bit freaked out at first, but they soon join her and laugh.
