Small Shock comes from Undertale, the 2015 indie role-playing game created by Toby Fox, who also composed its soundtrack and sound design. In the game, short effect cues like this punctuate battles, menu actions, and scripted surprises, helping even tiny moments feel expressive. As Undertale grew into a lasting online phenomenon, fans ripped and shared its distinctive effects across soundboards, streams, and fan edits. The shock cue survived because it is instantly readable, easy to layer, and closely tied to the game's playful but unsettling tone.
