Place it right on the cutest frame of a pet or baby edit, then follow it with Noot Noot Pingu for a second beat before returning to the main action.
このサウンドについて
This is a brief four-second clip centred on Otus sounding especially endearing, with a soft, sweet vocal sound that feels warm and gentle rather than loud or dramatic. It gives a cosy, affectionate feeling, like catching a small happy moment, and works as a light, charming reaction when something simply needs a touch of cuteness.
