Tempo

'Tempo' is an animatronic similar to the marionette from FNaF 2.

Description
Tempo has a 'blocky head' with blocky teeth, the reasoning for this may be he is meant to be 'kid friendly,' suggesting they would want him to be safe. He has red eyes and and glossy texture, implying he is new.

Behaviour
Tempo apprantly moves to the tempo of the music around him, as stated in the night 1 call. The issue with this is the fact that Tempo has a glitchy voice box. (Suggested by hearing a glitch noise before he attacks)

So the company give a CD player to rewind his song constantly, this possibly works due to the fact the tempo is very slow. Failing to rewind the box results in 'Children of the Night' playing until a glitch sound effect plays. After it plays, he will either A. Kill you. B. Drain 25% of your power upon hitting the door. Opening any of the two doors from there results in his jumpscare.

Trivia

 * The song is voiced by the developer, Dumbstorm
 * The 'Time' song can be heard from anywhere in the building. Even in your office, but it is VERY faint.
 * He is never seen on camera.
