Freddy-creates his own clone, which can not be distinguished from the real Freddy. The clone goes to the office, causing the guard to be distracted by him.

Bonnie-plays the guitar loudly, causing a sound wave. This wave stuns and blinds the guard for a few seconds. Before the wave reaches the guard, a loud guitar sound is heard so that the guard has time to close the doors or check if someone is nearby.
