On this page of the FNAF Security Breach guide, you will find a walkthrough for the Dumpster Diving quest. Here, we recall what is the goal of visiting Bonnie Bowl and how to defeat Chica.
Visiting Bonnie Bowl
You'll find the Bonnie Bowl Pass in the security room at Fazer Blast. In Bonnie Bowl Pass, there is an item that will be needed in order to dispose of Chica. So you're going to have to make the trip whether you like or not.
The attraction itself is on the third floor of Atrium. It is patrolled by S.T.A.F.F. bots, but you should pass them without any problems, as they are only located at the entrance and do not have patrol routes anymore. .
The item you need is at the food dispensary - simply enter the back room and you'll find the gift box containing Monty Mystery Mix. .. The item will serve as bait.
Chica will meet her doom at the compactor found in the kitchen. . However, before you can use it, you have to supply it with power. To locate the generator, follow the cable. It will lead you to the door on the other side of the room.
When you start the generator, go back to the compactor and put the Monty Mystery Mix in it.
Then, go to the table on the opposite side and press the button next to it.
Completing Chica's Beak mission is rewarded with an upgraded Voice Box. You have to install it on Freddy. To do that, travel to Parts and Service. You can use the elevator in Roxy's room.
Once you've reached the area, interact with the computer and enter the chamber. You have to face a minigame in which you need to remember the order of objects and repeat it.
