90's Endoskeleton

In Five Night's at Fuckboy's 3, once the Past Puppet has been defeated, a portal will appear in Room 1. Entering this portal will lead to the death minigame map. If you go inside the Parts/Service Room, you will find an endoskeleton.

Did you guess it yet? You'll be fighting the endoskeleton. He looks just as he is Five Night's at Freddy's 1.

He has [???] HP, and is way stronger than the Past Puppet that unlocks him.

Once Springtrap defeats the 90's Endoskeleton, Golden Freddy can battle the 80's Endoskeleton.
