So the title is "THE SILVER EYES"

Look at the background! Bonnie Foxy and Chica! They weren't there before! Only on this book cover!

The only thing i can think about, is purpe guy's eyes... Does this count as silver? Or this refers to Springtrap's white glowing eyes? I know, these two are technically the same, but nah, you get the point...
And still it can be a tottaly different thing... So what do you guys think about this?
