Five Nights at Freddy's teases sequel in end credits scene

With the massive box office success that Five Nights at Freddy's is, it wouldn't surprise any of us if Blumhouse was already working on a sequel to the animatronic horror movie. A tease for another movie may have been hidden in the first film, if the end credits are to be believed.

As fans pointed out on Reddit, at the end of the credits you can hear an animatronic voice spell out the words "come find me." Many think this is a message from the movie's antagonist, William Afton.

There are spoilers below:

Afton may have been dealt with by the end of the film, but his final words are "I always come back." This does indicate he'll make his return for the sequel. Another theory points to this message coming from Mike's brother Garrett, who could still be looking for his big bro to save him.

What do you think this message could mean?
