Place it near the end of a cute animal edit, after the main action has settled, then follow it with Noot Noot Pingu for a second animal moment before the video closes. That order keeps the focus on the animals and gives the edit a clear finish.
About this sound
This 6.6-second clip is a raccoon humming a low, steady hum in a repeating humhumhumhum pattern, with no words or other sounds in the mix. It feels warm, sleepy and quietly funny, like a small animal contentedly singing to itself. The soft, unhurried rhythm makes it easy to smile at without it demanding attention.
