The moon was out, casting shadows to form on the Whomping Willow tree on the grounds. Winky was walking around, everyone was sleeping, so she was sure she wouldn't get caught. No one was supposed to see her; she was to hide from everyone and become invisible if she did get looked upon. She watched curiously as shadows converged among the roots, the branches not moving at all. Coming closer, she noticed a shining material-like substance near a large root, but just before she got close enough to touch it, the branches began moving again; she disappeared with a 'pop'.
