Maintenance Menu:

You might've been wondering what's the maintenance icon in the bottom left of the monitor screen.

That icon is for the maintenance menu, where you'll repair the ventilation after it breaks.

If you don't repair it after it breaks, you'll run out of oxygen, and will result in a Game Over.

Circus Baby:

She'll start on the Storage Room, will then move to the Dining Area, then the hallway, and afterwards, she'll enter your office.

Once she's inside the office, you have to hide under the desk, and wait until she leaves.

Bon-Bon:

I decided to take out Bon-Bon from Funtime Freddy's stage image.

He now starts on the Storage Room, will then move to the Dining Area, then to the hallway, then to the Restroom, then the Left Vent, and afterwards, to the vent entrance.

Once he's on the vent entrance, you have to hide under the desk, and wait until he leaves.
