Vent seals are not a separate item but a crucial function of the camera system. When Springtrap enters a ventilation shaft, a red 'X' will appear over the corresponding vent camera icon. By clicking on that vent camera and then double-clicking the vent entrance, you can seal it off, forcing Springtrap back into the main camera system. This is your only defense against him using the vents to bypass your lures. Prioritize sealing vents that lead directly to your office (Vent Cam 14, Vent Cam 15). Mastering quick vent sealing is essential for survival on later nights.
