Withered Chica

Withered Chica is an animatronic in Ultimate Custom Night and was a main antagonist in FNaF 2.

Appearance
Withered Chica is Chica. She is a yellow chick with a orange beak. Her jaw is open and she wears a white bib that says: Let's Eat!!! Her feet are orange and she has tears on all of her limbs. Both her hands are torn of revealing wires.

Mechanic
Withered Chica: She is the last of the five vent-crawlers. Withered Chica can be blocked by the vent snare as well as the vent door. Unlike Ennard and the others, she gives no audio cue when she is at the door, meaning you need to track her position using the vent radar. If she reaches the vent door, she will become stuck in it, preventing you from closing it for the rest of the night. While her girth prevents Ennard, Molten Freddy, and Springtrap from passing, Mangle can still get through. While this may seem like a strategic advantage, keep in mind that Withered Chica may eventually wiggle free and jumpscare you.

Strategy
Every once in a while or when you hear banging in the vents, check the vent radar for movement. If you see movement near the vent opening sht the door before she can get stuck.
