the models used to look like this when they were finished, they had a different texturing and meshing of the model, before they were modified from what they are now in mid-development.

what you will see here is the first sugar model (yes, it was literal candy but with an ugly proportion), it was changed because I didn't like it because it didn't fit with the range of the animatronics.

was replaced by the new sugar model as you see it now.

you will also note that golden freddy was planned to appear in the early stages of development, but then was dropped and replaced by shadow lockjaw (and no, he will not be returning in this game).

Ghoul balloon boy is originally from the original trtf,which was a hallucination when you met him in front of you,he was planned to appear but was dropped in the end,also replaced by lockjaw.

Finally, the models are one year old after being made in January last year, including the development of the game.
