Put it just before a scare or a failed run in a gaming montage, then follow it with the FNAF 2 Jumpscare Scream for the payoff. Let it introduce the bigger moment, not carry the climax itself.

This is a very short, high-pitched childlike giggle linked to Balloon Boy, lasting just over a second. It begins with a small, cheerful sound, then quickly feels wrong and makes listeners brace for an irritating interruption. It comes from Five Nights at Freddy's 2, released in 2014, where the character appears and disrupts the player's night.
