In the FNAF 2 files, shadow bonnie's name is just random letters. His name in the files is "RWQFSFAXC". Knowing how tricky scott is I decided that he wouldn't just make it something random like that. So after putting the name through multiple ciphers, I decoded it using the Vigener cipher, which requires a key. I tried out multiple keys relating to the game only to recieve nothing, so I let an automated website go through it to try and decode it. After waiting, I finally recieved somethng. It was able to decode his file name into "TOTHENTHE." It found this with the key "yixyoshq', which has a calculated 91.657% chance of being the correct key. This may or may not be a coincidence, but I just figured i'd point it out since scott is a mad genious with hiding secrets. Try more ciphers on the name, it might have meanings that I missed.
