BB(Balloon Boy)

BB

BB firsts appears in Fnaf 2 and is only inactive on Night 1,in all of the other nights he is active,BB first starts off in the game area and he will eventually go into the left air vent so that he can sneak into your office,every time he moves in the vent you can hear him say 'Hi' or 'Hello' or you can just hear him giggling,BB is one of the three animatronics that doesn't actually kill you,instead,BB will enter your office and will just stand there for a little bit and then when you are looking at your monitor,BB will take the batteries from your flashlight meaning that Foxy is most likely going to kill you,in order to stop BB,you must first wait till he has can be seen in the left air vent in your office and then put on the Freddy Fazbear Head until he leaves,note that you must be careful as the sound of him exiting could be a different animatronic leaving,once BB has left,he will return to the Game Room,the only times that BB will NOT appear(not including Night 1),is when it is close to 6AM or Foxy's AI is set to 0.In UCN(Ultimate Custom Night),BB acts pretty much the exact same as he did in Fnaf 2,but instead when he is about to enter your office,all you have to do is close the side vent(which is where he is coming from) and then wait till you here him go away.BB also appears in Fnaf VR in the Fnaf 2 levels with the same mechanic from Fnaf 2,also,BB does appear in the Curse Of Dreadbear in the Trick or Treat level.Finally,BB appears in Fnaf AR and in this game(unlike in his past appearances) BB does actually try to kill you and even jumpscares you.
