Place this clip at the reveal moment in your edit, just after a failed hiding attempt is shown. Follow it with a run vine sound effect as the person bolts, then finish with a scream meme sound effect for the chase payoff.

This is a roughly ten-second French voice clip of someone saying 'Je sais où tu te caches' with a stern, hunting delivery. It feels theatrical and awkward in a funny way, turning an ordinary discovery into a mock chase driven by overblown suspicion.
