Place this clip at the very start of the edit while the lobby scene plays, then switch straight to a FNAF Jumpscare Scream for the scare, and finish with a Roblox Oof Sound when the run goes wrong.
About this sound
This is a roughly 31-second light instrumental elevator tune with a smooth, cheerful loop and no vocals. It feels calm, patient and a little silly, like time is politely standing still. It comes from the starting elevator lobby in Roblox Doors, where it plays while players wait before a run begins.
