Chica

Chica (also fully known as Chica the Chicken) is an antagonist in Five Nights at Freddy's. Chica is an animatronic chicken and children's entertainer housed at Freddy Fazbear's Pizza, along with Freddy Fazbear and Bonnie. She is the backup singer standing on the right-side in Freddy's band. At midnight, she is left in a "free roaming mode" until 6 AM, to prevent her servos from locking up.

Along with the other animatronics, Chica will try to forcefully stuff any human seen after hours into a Freddy Fazbear suit, resulting in death.

Apperance
Chica is a bright yellow animatronic chicken with a spherically-shaped head, orange beak, magenta eyes, and black eyebrows. On the top of her head are three "tufts" of feathers. She has two talons from each of her orange feet. She wears a white bib that reads "LET'S EAT!!!" in yellow bubble letters, outlined in purple and the bib is flecked with tricolored triangles in patterns of three, and what appear to be tiny stylized pizza slices.

Like all of the other animatronics at Freddy's, she has an out-of-place set of blocky teeth sticking up from her lower beak. Her endoskeleton teeth can also be seen within the back of her mouth, though these are only clearly visible in certain angles.

The Cupcake
The Cupcake is an object-like character from a tray carried by Chica with her left hand. It has pink-frosting with two large yellow eyes, a yellow-striped birthday candle with a vinyl candle-light, buck teeth, no wrapper, and, like other animatronics (except Foxy and Golden Freddy), has black eyelids.

The Cupcake will disappear when Chica is off the stage. It is unknown why, or how.

The same Cupcake can be also seen inside the Office located at the top of one of the monitors from the right. Due to its appearance that does not affect gameplay, it has nothing to do with the player, nor attacking/jumpscaring them.

Behavior
Chica will begin to move around halfway through Night 1, and makes quieter footsteps then Bonnie. Chica will always appear on the right door of your office, and the sooner you shut the door, the sooner she will go away. Sometimes, Chica will make no noise, and will only say “PIZZA!”. If Chica says this, then you must shut your door or it will result in a death. Chica may also appear on the left side of the office on Night 4, but this is all a trick to waste power. If Chica appears here, then it’s okay to not shut the door.
