Five Nights at Freddy’s: Sister Location was a weird pivot. Scott Cawthon basically threw out the "sit in an office and stare at doors" mechanic for a linear, narrative-driven experience. But then, the fans got loud. They wanted that classic, high-stress resource management back. So, Scott dropped the custom night sister location update in December 2016, and honestly, it changed the entire trajectory of the series lore. It wasn't just a gameplay mode. It was the moment we realized Michael Afton was literally rotting from the inside out.
People usually treat DLC or extra modes as "non-canon" fluff. Usually, that’s a safe bet. Not here. While the actual gameplay of defending a private office against Bidybaps and Bonnet is considered non-canon (because, well, the animatronics were already scooped by then), the cutscenes you get for beating the presets are 100% the backbone of the FNAF timeline. If you haven't sat through the frustration of Golden Freddy mode on 10/20 difficulty, you've missed the literal "skin-crawling" reveal of the Purple Man's origins.
The Brutal Reality of the Private Room
To even access the custom night sister location content, you technically had to beat the "Ennard" boss fight in the secret Funtime Auditorium ending. It was a rite of passage. Once you're in the Custom Night menu, though, the vibe shifts. You aren't crawling through vents anymore. You’re back in a desk. You’ve got power levels to watch. You’ve got oxygen to manage because if those vents get blocked, you black out.
The mechanics are a frantic mess of audio cues and visual checks. Take Yin-Yang, for example. You’re juggling Yenndo, who drains your oxygen like a vacuum, and Lolbit, who creates a literal "Please Stand By" visual obstruction that you have to type "LOL" to dismiss. It sounds goofy. It feels like a meme. But when you’re on the final hour of a 10/20 run and your heart is hammering against your ribs, it is the furthest thing from funny.
Scott designed this specific version of custom night to be a "best of" compilation of Sister Location’s mechanics, but refined. It’s tighter than the main game. It’s meaner. Ballora doesn't just sing; she approaches from specific sides with a directional audio cue that requires actual headphones to track. If you’re playing on laptop speakers, you’re basically dead meat.

Those Infamous Cutscenes and Michael Afton
This is where things get heavy. Every time you beat a difficulty level in custom night sister location, you get a 2D-style minigame. It looks like a simple Atari-era walk down a neighborhood street. At first, Michael looks like a normal guy. The neighbors wave. Everything is bright.
Then the decay starts.
Over several cutscenes, Michael’s skin turns from a healthy peach to a sickly green, then a bruised purple. By the end, he’s a literal walking corpse. The neighbors hide behind their fences. The music, which started as a cheerful tune, becomes distorted and slow. It's a masterclass in environmental storytelling with very few pixels. When Michael finally collapses and vomits the robotic remains of Ennard into the sewer, and we hear Circus Baby’s voice whispering "You won't die," everything clicked for the lore hunters.
This confirmed that Michael Afton isn't just a random protagonist. He's the son of the killer, he’s undead, and he’s the one we’ve likely been playing as in several other games. This update effectively bridged the gap between the 1980s setting of the earlier games and the futuristic, sci-fi horror of the underground bunker.
Breaking Down the Presets
You can't talk about this mode without mentioning the presets. They aren't just random groupings. They’re themed nightmares.
- Angry Bards: It’s basically just the "noisy" animatronics. You’ve got Ballora and the Bidybaps. It forces you to rely entirely on your ears.
- Freddy & Co: This one focuses on Funtime Freddy and his hand-puppet Bon-Bon. You have to listen for which side Freddy is on. If he says "Go get 'em!", you shut the opposite door. If he says "Surprise!", you shut the side he's currently on. It’s a mind game.
- Golden Freddy: The 10/20 beast. Everything is set to max. Most players never beat this without a very specific "click-pattern" strategy.
The strategy for 10/20 in custom night sister location is less about reaction time and more about rhythm. You have to check the cameras for certain characters at exact intervals. If you spend more than a second looking for Bonnet (the pink rabbit who walks across the screen), you’re probably going to lose power or get jumped by Electrobab.
Why the Fanbase Still Obsesses Over It
It’s about the challenge. FNAF games have always had a high skill ceiling, but the custom night sister location update felt like a direct response to the "Main game is too easy" complaints. It also introduced characters that never got their time in the limelight during the main campaign. Lolbit and Yenndo were just rare Easter eggs before this. Suddenly, they were primary antagonists.
There’s also the "Springtrap" teaser. If you’re one of the legends who actually beat the Golden Freddy preset on the hardest difficulty, you got a final cutscene. We see the burnt-out remains of Fazbear's Fright. We hear Michael talking to his father, William Afton. "I'm going to come find you," he says. Then, Springtrap steps into the frame.

It was the ultimate hype generator for FNAF 6. It turned a spin-off style update into a mandatory piece of the puzzle.
Honestly, the sheer amount of content Scott packed into a free update is still wild by today's standards. Most studios would have charged ten bucks for a new office, ten new AI characters, and several minutes of lore-heavy animation. Instead, it was just... there. A gift to the people who spent hours dissecting his source code.
Handling the Characters (A Quick Survival Guide)
If you're jumping back into the custom night sister location grind, you need to know who is actually dangerous and who is just a distraction.
Ballora is your biggest threat in terms of pure focus. She doesn't show up on cameras. You have to hear her music box. If it gets loud in the left ear, shut the left door. Simple? No. Because while you're listening for her, the Mini-Reenas are likely covering your screen or draining your oxygen.
The Bidybaps are vent-crawlers. You'll hear them thudding. It’s a distinct sound, different from the metallic clanking of the others. Shut that vent immediately.
Bonnet is the "troll" character. She just peeks out and starts walking across the office. You have to click her nose. If you miss, you’re done. It’s a classic "distraction" mechanic designed to make you panic and forget about your power levels.

The Technical Side of Things
Technically, this mode runs on a modified version of the Clickteam Fusion engine, just like the rest of the classic series. This means the AI isn't "thinking." It's running on a series of random number generators (RNG) and timers.
Each character has an "opportunity" timer. For example, every 5 seconds, the game might roll a die. If the number is lower than the character's difficulty setting, they move. This is why 10/20 feels so chaotic—the "dice" are being rolled constantly, and the odds are heavily stacked against you. You aren't playing against a ghost; you're playing against a very aggressive spreadsheet.
Actionable Tips for Mastering Custom Night
If you're actually trying to clear the board, stop playing "fair." Use these tactics:
- Audio Hijacking: Turn off your music. Use high-quality, over-ear headphones. The directional audio for Ballora is literally the only way to track her.
- The "LOL" Reflex: Keep your left hand near the keyboard. When Lolbit appears, don't use the mouse to click the "X." Type L-O-L. It's faster and keeps your cursor centered for Bonnet.
- Camera Camping: In the harder modes, don't flip through cameras. Pick the one that monitors the most dangerous threat (usually the vent or the power-drainers) and stay there. Flipping cameras drains power.
- Oxygen Over Flow: If your oxygen drops below 20%, you're effectively dead because the screen blur makes it impossible to see Bonnet or the door lights. Prioritize the vent-draining animatronics above almost everything else.
The custom night sister location is a testament to how much a developer can do with limited assets. It turned a game that was originally criticized for being "too different" back into a classic FNAF experience while doubling down on the weird, dark story of the Afton family. It’s frustrating, it’s loud, and it’s occasionally unfair, but it’s the definitive way to experience the Sister Location era.
Go back and try the Golden Freddy challenge. Even if you fail, the rhythmic chaos of managing five different threats at once is a gaming high you don't find in many other horror titles. Just remember to watch the power. It goes faster than you think.
Next Steps for Players:
- Review your audio settings to ensure 3D spatial sound is enabled for Ballora's tracking.
- Practice the typing reflex for Lolbit in a lower-difficulty mode like "Girl's Night."
- Watch a frame-by-frame breakdown of the "Michael's Decay" cutscene to spot the hidden details in the windows of the houses.
