In February 2019, a rumor spurred by YouTuber Shane Dawson and his experience at a local Chuck E. Cheese circulated in which he theorized that they recycled pizza from previous orders due to several pies having noticeably mismatched crusts and wrong or oddly-placed toppings. Steel Wool made reference to this incident in Five Nights at Freddy's: Security Breach in a message bag that can be found in one of the Superstar Daycare's side birthday rooms, saying:

Ignited Freddy and Ignited Bonnie from The Joy of Creation both make cameos in Five Nights at Freddy's: Security Breach as an Easter egg on the "House of the Bear" arcade cabinets: Ignited Freddy on his own for the original, and together with Ignited Bonnie on "House of the Bear 2".

Most of the locations and structures in the Freddy Fazbear's Mega Pizzaplex were based on places that the developers had actually been to throughout their childhoods, high school jobs, and as parents planning parties for their children.
