The update's development has begun around February 2016. On Febuary 18, 2016, fnafworld.com was updated, featuring the Halloween animatronics (excluding Nightmare Mangle), Chipper from Chipper and Son's Lumber Co, William Afton (using his Five Nights at Freddy's 3 8-bit sprite), and Coffee from The Desolate Hope. An update to the IndieDB page also featured Scott himself (as his avatar) as a playable character.
On April 1, 2016, a kitten from one of Scott's older games, Kitten In The Crowd, appeared as an April Fool's joke. It was removed the next day. The kitten can be found in the minigames Foxy.EXE, and FNaF 57 Freddy in Space.
On May 1, 2016, a rainbow with buckteeth, later known as Chica's Magic Rainbow, appeared.
Two days later, Update 2 was set to be released on May 13, 2016.
- Scott Cawthon has confirmed that there will be no Update 3.
- When Update 2 first launched, a bug caused the fan trophy to be removed, even if the player has all 48 characters. This was later fixed in v1.24.
- This is the first games in all Five Night at Freddy's Franchise to have credit in end of games.
