Toy Chica (known as Chica 2.0 in-game) is the redesigned version of Chicaand one of the secondary antagonists in the Indie horror game; Five Nights at Freddy's 2.
Five Nights at Freddy's 2
Like Toy Freddy and Toy Bonnie, Toy Chica first starts at the Show Stage. She is known to approach through the Main Hall and Party Room 1, also appearing in The Office's main entrance at times. Another path she may take begins with her entering through Party Room 1 before crawling into the Left Air Vent to make her way to The Office.
Though she is usually the second animatronic to leave the Show Stage on the first few nights, she is very inactive on later nights. This is due to Foxytaking her place in the entrance hall, preventing her from leaving. However, she will become active again starting on Night 5, as will the other Toy animatronics.
When the player spots Toy Chica in the Left Air Vent's blind spot, they must equip the Freddy Fazbear Mask 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 only appeared as a head in the office, however she is a playable character in the "Chica's Party" minigame
