Place it at the end of a scene, after the mischief has played out, so it works as the closing line. Put No No Wait Wait just before it to build the plea, then follow it with Kids Cheering once the good behaviour lands, turning the scolding into a small celebration.
About this sound
This is a short 1.5-second voice clip of a soft, gentle voice saying 'be a good girl' in a calm, coaxing tone. It feels playful and slightly teasing, like a light scolding that is meant to make someone smile rather than feel told off. The delivery is warm and affectionate, turning a simple instruction into a cute, meme-ready moment.
