Five Nights at Freddy’s Security Breach: how to get to the sandrop's room, or how to open a secret door

For all the following actions you need a phase-chamber, which can be obtained as you progress through the monty.

She is in the fazbear theater in the kindergarten location. Entering the theater in the distance, you can see a poster with a movie about pirates.
The painting depicts animatronics, which we must find and take pictures on the phase-camera. (the screenshot shows the completed actions, that's why animatronics have their eyes shining)

Foxy is very close, turn to the left of the poster and look for the stairs down.
We go down and go into the red doors next to the inscription B1. Next, we go to the end of the room and here we take a foxy. If you did everything right, his eyes should light up..

Chica is on the first floor of the atrium, next to Fazer Blast, in the bay (or what is it called)
Everything is exactly the same, fotay.

We can find him in the room with the rooms of the animatronics.. We go through this door.

All go too, until we find the save with freda's poster
I think to explain, what not to do.

We are looking for Bonnie on the fourth floor, where we come through the fazcade elevator on the third. We need to get into the big tunnel, where we ran from the musicman. The entrance there is in the upper right corner of the room, through the red door.
We go to the end and see bonnie.

Returning to the same secret door, and now we can enter it.
