Place it at the turning point of an edit, after a normal character moment and before the reveal. Follow it with the Dun Dun Dun sound to underline the twist, or lead into it with the Classic Error Sound when the computer starts malfunctioning.

This is a roughly 14-second horror take on Sprunki's Mr Fun Computer, built around distorted electronic tones and a warped, unsettling computer character presence. It feels creepy and tense, like a cheerful machine turning sinister, with a glitchy edge that keeps listeners on guard. It comes from Sprunki, the fan-made horror spin on the music-mixing game Incredibox.
