The kids decide to start their own band and try to find some instruments. Oobi discovers that he is an instrument and can make a sound by clapping his hand with Grampu. Soon they are all making music together and the Oobi band is born. — ABC Television
Oobi is watching a rock band perform on television. He greets the viewers and invites them to dance to the music with him. Uma sees Oobi dancing and asks him if they can form a band with Kako. Oobi excitedly agrees and turns off the television. He and Uma run to the kitchen, where they find Kako and ask him to join their band. Kako wants to, but he tells the others that they need instruments in order to make music.
The children search for makeshift instruments around the house. Kako tries to make a sound with a banana, but is unsuccessful. He blows on a bottle of fruit punch, which makes a sound, and decides to use this as his instrument. The next scene shows Oobi trying to make music with a bowl of spaghetti. He strums and swings it, but has no luck and instead ends up covered in spaghetti.
Later, Uma tries to find something that will make a noise after being hit with a spoon. She comes across a pot that makes a clanging sound. Uma happily asks the viewers to make music with her. The scene switches to Oobi, who tries to use eggs as an instrument. He shakes it and squeezes it, but to no avail. Kako unexpectedly startles him, causing an egg to crack on top of Oobi's head. Oobi is discouraged and tells the others that he has not found an instrument. He lies down on the kitchen table and unintentionally makes a clapping sound. This gives Oobi the idea to use himself as an instrument. He calls Grampu and asks to clap with him.
As Oobi and Grampu clap, Uma and Kako use their instruments to play music. The following interview segments involve Oobi asking preschoolers if they know how to play instruments. Oobi and Grampu then play a music game, in which Grampu plays an instrument and asks Oobi to guess which one he is playing. The episode ends when they discover Kako has made a new band, with a bunch of ducklings.
