"Music!" is one of the Oobi shorts.
Oobi and Kako are in front of a piano with a tin can and a water bottle. Kako taps his fingers on top of the can, using it as a makeshift drum. Oobi blows air on the bottle, creating a low whistling sound. They tell the viewers that they are making music. The camera zooms out as Uma walks on screen and announces that she wants to make music as well.
Oobi and Kako shake their heads no and tell her that she can't make music since she has no instrument. After thinking for a while, Uma comes up with an idea. She decides to sing and use her voice as a musical instrument. The kids shout "Uma, music!" as they use their instruments to play a tune together.
