Withered Bonnie and Withered Chica are formidable threats that primarily use the ventilation shafts, similar to their Toy counterparts, but they are much faster. When you hear a distinct metallic clanking sound or see them in the vent openings, you must immediately equip the Freddy Fazbear Head. They will not hesitate to jump scare you if you are too slow. Keep the mask on until you hear the 'thud' sound indicating they have left. Unlike the Toy animatronics, Withered Bonnie and Chica can appear very quickly, so constant vigilance of the vents is crucial. Avoid flashing your light at them in the vents; the mask is the only reliable defense. Prioritize checking the vents after every music box wind or camera check.
