Place it at the reveal in a horror edit, after a warning cue and before a bigger scare. Start with Danger Alarm Meme Sound to build tension, hit this scream at the appearance, then follow with FNAF Jumpscare Scream for the full scare.
このサウンドについて
This under-a-second clip is a sharp, high-pitched scream from Tinky Winky, the purple Teletubby turned threatening figure in the fan-made horror game Slendytubbies. It sounds strained and slightly warped, and it feels both absurd and unsettling because a familiar children's character suddenly sounds panicked and dangerous. That clash makes a sudden scare feel funny as well as creepy.
