User blog comment:FazbearFreak/Scott's teasing something... for real this time!/@comment-27010092-20170612000731/@comment-30653199-20170612071630

I personally don't think it's a withered Baby, but rather a hybrid Baby.

The reason I think this is because she says in the source code that she will put herself back together. This means that this is Baby, having done the exact thing she said she would, having rebuilt herself using old parts and junk.

It would make sense, due to the slight cracks and withering around the eyeholes.
