Funtime Foxy can easily detect any forms of light, they also have a voice changer that they can use to lure people into traps. They don't really talk much but they can be just as dangerous as the other animatronics. And they will not stop at one human, they want revenge on all who locked them and the others down in the facility.

(Also, I wanna point out that I want Funtime Foxy's voice to sound completely different from the way they sound in the game, mainly because I feel like their in game voice just will not fit their character in this film, so for those of you who want to do this role, try and come up with your own original voice for that you believe would suit the character.)
