Place it at the reveal, just as the neighbour is noticed, then follow with a short reaction sound to sell the surprise. A well-timed Bruh sound follows it, while an Oh My God reaction heightens it before the scene moves on.

This short Hello Neighbor clip runs for about 3.7 seconds and keeps its focus on the familiar two-word greeting at its centre, presented as a compact meme sound. It feels playful and a little unsettling, like spotting someone watching from next door, with a light teasing edge that makes the greeting land as a joke rather than a welcome.
