A small viewing ground. From the farther left contains at least two pipes. If you hack inside the room (In the update of Chapter 2) is revealed that the room have the eight cutouts on the left,an cutout of Bendy saying "WANDERING IS A TERRIBLE SIN" and some stairs.
A Bendy cutout can be seen in the recording studio when Henry first enters the projection booth. If the projector is turned on, then turned off, the cutout multiplies; the same number of cutouts can be seen in the audience when Henry is in the recording studio. Up to nine cutouts can appear.
After activating the flow pump in Sammy's Sanctuary, Sammy Lawrence can be seen in the audience, with his gaze constantly following Henry. From this moment, all nine cutouts (if Henry multiplies them enough to unlock the "Strike Up the Band" achievement) disappear with only one remaining.
