Place this clip right before the reveal or chase payoff in your timeline, not over dialogue. Follow it with a sudden scream or impact hit for the scare, or switch straight to the Coffin Dance Meme Sound when you want the tension to flip into a joke ending.
About this sound
This 10-second clip is a repetitive dum dum musical rhythm linked to Foxy, the fast red fox animatronic. Its thudding bursts create a tense, urgent feeling, like something is sprinting closer with every beat. It comes from Five Nights at Freddy's, where Foxy is known for sudden high-speed runs from Pirate Cove toward the player.
