There are 5 animatronics hunting you down: Flowster, Blutty, Prototype Flowster, Jester Victor, and Jester Susan. Flowster and Blutty work the same way: check the vents doors to see if they are there, and flip the Flowster mask on if they are. Prototype Fstr., Jester Victor, and Jester Susan work differently, however. Prototype Fstr. resides in your office. If he moves, it is your job to administer a controlled shock. Don't, and "I don't think he moved" will be your last words. He cannot be fooled by the mask. Jester Victor can't be seen in the vents, and when he gets to your office it's game over. Make sure to close the vent when he gets too close. He cannot be fooled by the mask. Jester Susan resides in the prize corner and her music box will regularly need to be winded up. Don't let her wind meter fall completely. She cannot be fooled by the mask.
