A bare endoskeleton can be seen in the Prize Corner and Left Vent, though it never attacks the player. There are some interesting fan theories about which animatronic this endoskeleton belongs to.

Endo-02 is an endoskeleton designed for the withered animatronics and some toy animatronics in Freddy Fazbear's Pizza during the 1980s era. Five Nights at Freddy's 2 marked the extra suitless endoskeleton's first debut.

Physical Appearance

This endoskeleton seems much detailed in appearance when comparing to its another variant Endo-01. Shaded with series of gray and silver colors, it sports with three rib-like cages, cylinder limbs with spiral springs, a wide mouth filled with squarish teeth, and flat, three-toed feet.

Its overall appearance bears a lot of striking similarities to Withered Foxy's endoskeleton due to its nearly identical body structures, with ears in exact same shape but facing in a different way. Endo-02 also has hazel-blue eyes similar to those of Withered Freddy's.

From the second game, its head is designed to feature tiny connective wires, containing wires for inside some parts of the limbs, and a bundle of long wires can be seen sticking out behind its back; apparently identifiable when at the Prize Corner. In Help Wanted, however, these are removed possibly in order to reduce the polycount.


Akin to other endoskeletons, Endo-02 has functional eyelids, joints, jaw, knuckles, and ears (which is not the case for Withered Chica and Toy Chica). They are created as inner skeletons for the older withered animatronic cast at first, and reused for the toy animatronics albeit Balloon Boy, JJ, and the Puppet.
