Place it at the exact beat where a character or object gets shocked, then follow it with Vine Boom for the payoff and use Pew Pew just before it when a gadget is aimed. That order keeps the shock as the centre of the scene and lets the other effects build around it.
About this sound
This is a short sound effect of four repeated electric zaps, lasting about seven and a half seconds, with a sharp crackling buzz in each burst. It feels sudden and jolting, like a cartoon shock, so it lands as funny and startling rather than serious, giving a listener a quick jolt of energy and surprise.
