Sparky The Dog

Sparky is the first true FNAF hoax, he comes from the first game and is the only half-believable hoax. He can allegedly be seen in Cam 5, but Scott Cawthon has confirmed that this is a hoax and he is quoted as saying it was a "hastily painted mess".

However, Fetch from the official Fazbear Frights series may have taken inspiration from Sparky the Dog.
