So, our story begins after the fnaf 3 fire. During that time (2023), Toby was working on deltarune. He wanted to speed up development so his solution was to find a piece of software that can help. One day, he came upon the Fazbear's Fright auction from the fire.

One of the listings were old parts from the attraction's arcade (cam 6 and 7 from the original game). He got the parts and ported the files to deltarune. However, one of the parts turned out to have the mimic one program in it. So, what happens when you let the most intelligent but dangerous AI with a complete history of Fazbear?

Simple, you get a mishmash of fnaf and undertale in one game, resulting in the creation of FLAWFROND. Toby abandoned the project at that point, as it became more fnaf oriented. However, the files were soon leaked, allowing the world to learn the truth, in this mysterious fnaf world inspired version of deltarune.
