The vent is reused from the Right Air Vent from Five Nights at Freddy's 2.
- When Sugar is in the vent, it seems that she is only a head and an arm.
- When Chica is in the vent, her feathers clip though the vent, an error that was also in FNAF 2.
The Ceiling Vent is a location in The Return to Freddy's 2 within Fredbear's Family Diner, the vent connects the Main Hall to The Office. Kitty FazCat and Sugar pass through the vent while heading towards The Office.
- Originally, Bonnie was going to be able to enter the vent, but this was cut.
- The Air Vent's texture is actually taken from FNAF2's Right Air Vent.
