Bonnie

Bonnie is a selectable antagonist.

Mechanic
He will appear in the left doorway, only visible by using the door light. Close the door on him as soon as possible to avoid a jumpscare from this friendly bunny.

Difficulty Level
A random number is chosen between 40 and 50, then subtracted by the AI level. This is the number of seconds until Bonnie can appear while the light is off. After Bonnie appears, another random number is chosen between 40 and 50, then subtracted by the AI level. This is the number of seconds before Bonnie jumpscares the player.

At 20 AI, Bonnie can appear every 20 to 30 seconds, then jumpscare the player in 20 to 30 seconds.
