Place it just after the reveal shot in a gameplay edit, then follow it with Enemy Spotted to underline the find and Okay Let's Go to move the scene forward. Use Click Nice after the next discovery, keeping Pete's moment as the centre of the sequence.
关于此声音
This is a short Japanese voice line from Deltarune Chapter 5, lasting about a second and a half, in which a character announces that Pete has been found. The delivery is bright and excited, with the lift of a small discovery suddenly landing, so it feels playful and triumphant rather than dramatic. It comes from a spoiler moment in the game's flowery chapter.
