Mangle followed Nightmare Chica with caution, but when she got the
chance, she sprung up behind her. "Wa-u-gh!" She bellowed,
attempting to frighten her. Mangle ran away quickly and looked at
Nightmare Bonnie. "Come on! I thought I saw something over there!"
She gestured towards Toy Bonnie.
(I believe Mangle is Female, so I'll write, "She" and "Her")
