There is no widely documented origin for Naiden 2, and the title appears to come from a user-generated soundboard rather than a named film, show, or song. Its Russian title simply means found, which explains why creators use it as a short discovery cue in prank, reaction, and hide-and-seek edits. Short clips like this travel well online because they are easy to drop into a video without needing context, and the 1.7-second length fits the fast pace of short-form content. It remains useful because the idea is universal: everyone understands the beat of finding something.
