These are the animatronics from the first Freddy Fazbear's Pizza opened 1985.

These animatronics were made in house by Fazbear Entertainment (What Golden Time Enterprises was renamed to when it was sold).

Due to being very early designs made in a short time period, they have considerably ugly designs, however they were still popular with kids.

In 1987 when the new and improved Freddy Fazbear's Pizza was set to open, these animatronics were retrofitted with new designs as well as being given new facial recognition software (the unwithered designs).
However these were scrapped as being viewed by the company as ugly and outdated, they decided to make entirely new versions of the characters nicknamed the Toy Animatronics.

They were left in the backroom at this location where there parts and pieces would be used for the toy animatronics, thus becoming the withereds.
