I'm afraid it's been, 4 years. That this project has been in development, now i attempted many times to make this mod a thing but failed at each attempt until now. Ladies and gentleman i can finally announce Fnaf Universal 3D. This mod was originally posted on Planet Minecraft but it is making it's apparition in curseforge. Planet minecraft link:

Fnaf Universal 3D Is a mod bringing the horror of Five Night's at Freddy's animatronics to minecraft, the night are darker and not so lonely anymore. The mod features New animatronics, ones never seen before such as Dreamstalker Foxy, Phantomatic bonnie, and 10 others awaiting for your presence. The nights will not be so lonely.
It willl be necessary to have the mod Geckolib in 1.20.1 to make the mod work, which for here is the link:

Keep in mind the mod is heavy and laggy due to it's large numbers of details and voxels varrying between each animatronics, until i find a way to optimize them it's not recommended for low end pcs.
