Chica the Chicken is an animatronic with the soul of a child trapped inside her. Her voice is a high to medium pitch and has a sort of comfort to it. She is the nicest and the least frightening out of the five but she can get creepy fast. For scarier lines, she uses a deeper, more growly/unstable voice inflexion in her speech. Refer to the internet for examples. I do not necessarily want a replica, so do what you can with this information and create a unique distinguished voice!
