She is a yellow chicken with an orange beak, blue eyes, purple eyelids, eyelashes, and orange feet. She has a few 'feathers' that stick out of her head, almost like hair. She also has blushed cheeks, and looks much more humanoid than the original Chica. She wears a bib that reads "LET'S PARTY!" as well as a pink garment on her lower body which resembles underwear. She also carries with her a pink cupcake with large eyes. While on the Show Stage Toy Chica has her normal eyes and beak, but she removes them once she becomes active. It is unknown why she does this. Also, with her beak removed her endoskeleton teeth become visible.
She will start at the Show Stage and then head for the Main Hall. She is always the second animatronic to leave the Show Stage, but on later nights she becomes very inactive. However, she becomes active again on night 5 forward. When the player spots Toy Chica in the Left Air Vent's blind spot, they need to equip the Freddy Fazbear Head in order to get rid of her. Neglecting to put the Freddy Head on will result in the player getting killed by Toy Chica.
- Toy Chica is one of two toy animatronics to have her endoskeleton mouth visible, the other being Mangle.
- Toy Chica appears to hold her cupcake wherever she goes, even when she attacks, but the cupcake is not visible when she is in either the Left Air Vent, Show Stage, or Main Hall.
- Toy Chica was originally meant to "crawl" out of the vents just like Toy Bonnie.
