Chica seemed worried recently. You had noticed she hadn't had her animatronic cupcake with her.. you decided that this might be the cause of the chickens stress.

When you found him in the vents, you decided to go and return the cupcake to chica. Her eyes lit up when she saw you and her cupcake, literally. "Oh, my, god! You found him?! Where was he?" The chicken found words spewing out of her voicebox, but she was pretty talkative anyway.
