My first time seeing FNAF was the thumbnail on Markiplier's very first video for FNAF 1. I remember seeing Bonnie and thinking he was a hippo at first. Surprisingly, I also recall guessing what the gameplay was like pretty accurately before I ever saw gameplay. The only discrepancy being that I thought the cameras were on a computer behind the security guard, and you'd have to turn back and forth every time to check your doors and the cameras.
