Place it at the end of a short name-based exchange, just after the mention that sets it up, so the clip closes the bit. Pair it with the WhatsApp Message Sound for the incoming reply, then the WhatsApp Bass Boosted Sound when the group wants a second follow-up.

Kaalu is a short WhatsApp audio clip built around the single name, delivered in about three and a half seconds as a quick call-out. It feels playful and teasing, like a friendly nudge aimed at one person in the middle of a group chat, and it works best when the name itself is the whole point of the moment.
