"Bongo Drums!" is one of the Oobi shorts.
Grampu is playing a pair of bongo drums as Uma walks on screen. She marvels at the tune Grampu plays on the bongos and asks if she can play. Grampu lets her take a turn and plays a rhythm for her to repeat. She can't seem to get the hang of it, and instead of playing a beat, she just slaps the drum with her palm and lies there.
Grampu shows her the rhythm again, but she still can't figure out how to do anything more than slap the drum. Grampu decides to show her again, and she makes a nice rhythm, this time patting the bongo and making the same tune as Grampu. Uma and Grampu invite the viewers to clap along to the beat as the episode ends.
