Notes:

While watching this: http://youtu.be/4YWZ00H8ib0?t=2m34s (around 2:34 – 3:02)

They mention the call saying there was a yellow suit used. Never is it said it was a Freddy suit. They go on to say this suit could have been used for the events of the murders.

With Salvage staring me in the face, I noticed the shape and alignment of the teeth along with the white glowing eyes. Where have I seen this before?

FNAF 2. Maybe Shadow Bonnie wasn't a complete hallucination. Like the Marionette flashback/flash forward to FNAF 1, this character could have been behind the scenes the whole time.

Draw your own conclusions, but this new animatronic lines up way more closely with Shadow Bonnie than any other animatronic that has been presented in the first 2 games.
