The Shadow Bonnie! Aw man That's creepy! Look at how it looks like it's smilling evily at you! But it doesn't crash the game. The Shadow Bonnie appears after the death mini-games, right? Or was that Shadow Freddy? I forget.
No. If you look at it long enough, and if you don't put up your Freddy Mask/Put up your monitor in time, it will slowly dissapear, and crash your game. However, the game crashing is a 80/20 chance, in favor of crashing.
(I think he crashes your game? Think of it like Golden Freddy.)
EGADS!!! :O That reminds me, (old) Bonnie just randomly appeared in a nightmare I had last night! I don't quite remember what he looked like, but I do remember that he had completely black eyes, like how he sometimes looks when he's backstage in the 1st game.
