I found some random Fredbear, I don't know any more secrets but someone said there was a "new easter egg", Tell me about more easter eggs!

Edit: Found Springtrap and Withered Bonnie! Those really have good hiding spots, I also checked the textures and saw that there was "mike_jump" and "mike_wuz_here"... there was also the puppet. (The mike_jumpscare looks like some sort of puppet)
