The script is very short, but the character is important nonetheless. Nightmare Bonnie has a heavily distorted, almost unintelligible voice. (For those unfamiliar with the franchise, Nightmare Bonnie is a demonic-looking bunny animatronic). Make the vocals sound as unnerving and as upsetting as possible. If I get scared listening to it, you'll get the part.

Using a voice filter is a plus! As I said, I would prefer the vocals to be almost unrecognizable, if not completely unrecognizable as a human voice.
