NBB 3 Robots Jumpscare comes from a fan-made horror game entry built around killer robots, following the formula popularised by Five Nights at Freddy's. Its scare relies on the same sudden animatronic attack that made the FNAF jumpscare scream a staple of horror soundboards. Clips from the game were cut and shared on soundboards and in YouTube edits, where the short scream became a reusable effect separate from the full gameplay. It remains popular because it delivers an instant horror payoff without needing any visual context.
