Unlike other versions of Foxy, Mangle is meant to be a Pull apart, put back together animatronic, It is the most damaged Foxy variant.
Mangle is a white fox animatronic with an average height. Mangle has red cheeks, as well as lipstick haphazardly dotted on its elongated snout. It also has pink eyelids and long eyelashes. Its teeth are also smaller, but its endoskeleton's teeth are visible. A pink bow tie is also attached to its bent chassis. It also has a second, endoskeleton head, which bears Mangle's left eye on it. If it's looked at closely, it can be seen that Mangle has pink nail polish on its feet.
Exactly what its body looks like varies greatly, as in the original game it appears to have limbs in a different position each time it moves rooms. However, due to Five Nights at Freddy's: Help Wanted and Five Nights at Freddy's: Special Delivery being fully 3D, its body has a consistent appearance, oddly revealing it to possess 3 legs.
Week 6's songs are still the same, the only difference there is the whole week's music is pitch shifted a bit higher.
Scott Cawthon, the creator of the FNaF series, has announced that Mangle's gender is simply "yes". This is most likely a joke.
