Place this clip at the very start of an entrance moment, before any dialogue begins, then follow it with a kids cheering sound if the arrival is meant to read as a big reveal for the group watching.
このサウンドについて
This is a four-second voice clip of someone drawing out a single hey into a long, wobbly greeting that keeps going well past a normal hello. It feels playful, welcoming and a little over the top, like an excited friend making an entrance, which makes even a simple arrival sound like a small celebration.
