Hi Ultimateplayer939, we hope you are enjoying our game. The microphone can only spawn in one of two places: in the kitchen inside the fridge or in the assembly control over the console that is next to the window, this one is easy too miss.
Hi Ultimateplayer939, not necessary, all animatronics' quests related items will re-spawn if she ran out of quests. So her quest list can loop-over. This only happens if the item has been consumed however. So you may encounter that the tape is back to its place even if you used.
