The Return to Freddy's
Previously called "FNaF 3 Fanmade", The Return to Freddy's was placed between Five Nights at Freddy's and Five Nights at Freddy's 3. It contained the animatronics: Freddy, Bonnie, Chica, Foxy, Golden Freddy and Puppet, along with the addition of a new character "Sugar" (Who was actually Candy The Cat from Five Nights at Candy's),The game was popular because of Candy and because according to Poniator it had Scott's permission, this being false.
The game received copyright lawsuits from Scott Cawthon for the name FNaF 3 (so the name of the game was changed to The Return to Freddy's) and from Emil Macko (Creator of Five Nights at Candy's) for Use Candy the cat
