Five Nights at 39s isn't your typical Five Nights at Freddy’s clone. It’s weirder. It’s louder. Honestly, it’s a bit of a relic from a specific era of Game Jolt where developers were just trying to see how far they could push the FNaF formula into the realm of parody. Developed by 39Games, this fan game swaps out the existential dread of being stuffed into a suit for a green, glasses-wearing rabbit named 39 who just won't stop swearing at you.
It's crude.
If you grew up in the mid-2010s horror scene, you probably remember seeing Markiplier or Dawko lose their minds over this. But looking at it today, there’s actually a lot to dissect regarding how it flipped the script on horror mechanics. Most horror games want you to be afraid of the monster. Five Nights at 39s wants you to be annoyed by him, and that’s a surprisingly effective way to build tension.
The Weird Mechanics of Five Nights at 39s
Most FNaF clones follow a predictable loop: check cameras, close doors, save power. Five Nights at 39s keeps the camera bit but throws the rest of the rulebook into a woodchipper. Instead of managing a limited power supply, you’re basically managing 39’s ego and your own sanity.
The main antagonist, 39, is a green rabbit animatronic who spends his time wandering the halls of what looks like a typical pizzeria, but his goal isn't necessarily to kill you in the traditional sense. He wants to get into your office to harass you. If he gets in, it’s not always an immediate game over. Sometimes he just sits there. He talks. He mocks the player.
You have to boop his nose.
Seriously. The primary defensive mechanic in Five Nights at 39s involves clicking 39’s nose to make him leave. It sounds ridiculous because it is. But when you’re on Night 5 and the AI is cranked up, trying to find a tiny hitbox on a rabbit’s nose while he’s screaming insults at you is genuinely stressful. It turns the horror into a frantic clicking exercise.

Why the Humor Works (and Why It Doesn't)
There is a very specific type of humor here. It’s very 2017. If you aren't a fan of "edgy" humor or constant profanity, this game is going to grate on your nerves within five minutes. 39 is voiced with a thick British accent and a vocabulary that would make a sailor blush.
Some players find it hilarious because it deconstructs the self-seriousness of the FNaF universe. Others find it repetitive. What’s interesting is that the creator, 39Games, actually built a personality for the character. Unlike Freddy Fazbear, who is a silent stalker, 39 is a character you love to hate. He has motivations—mostly just being a nuisance—and that makes the gameplay loop feel more like a battle of wits than a game of hide-and-seek.
Technical Specs and Development History
Five Nights at 39s was built using Clickteam Fusion 2.5, the same engine Scott Cawthon used for the original series. This allowed for that familiar pre-rendered 3D look that defined the era. The game first popped up on Game Jolt around 2017 and quickly gained traction thanks to the "Let's Play" boom on YouTube.
The developer didn't stop at just one version. There have been updates and "remastered" versions that cleaned up the assets and balanced the AI. One thing that stands out is the office design. It’s cluttered, messy, and feels lived-in. It doesn't have the sterile, corporate feel of Fazbear Entertainment. It feels like a basement, which adds to the "indie parody" vibe.
- Release Year: 2017 (Initial)
- Platform: PC (Game Jolt)
- Engine: Clickteam Fusion 2.5
- Main Threat: 39 (the Green Bunny)
The game also features a variety of cameos and secrets. If you look closely at the posters and the camera feeds, there are constant nods to other fan games and the wider FNaF community. It’s a game made by a fan, for fans, who were perhaps getting a little tired of the same old scares.
Handling the Difficulty Spike
Don't let the jokes fool you. Five Nights at 39s is hard.

As the nights progress, 39 moves faster. His pathing becomes less predictable. You start having to manage the "Plushie" mechanic as well. There’s a small plush version of 39 that sits on your desk. You have to keep an eye on it. If you ignore it for too long, it’ll jump-scare you, often leading to a situation where the main 39 can sneak into the office.
It's a game of multitasking.
You aren't just watching cameras; you're listening for audio cues. 39's voice lines actually tell you where he is if you're paying enough attention. This was a clever bit of design. Most fan games just use random stock sound effects, but here, the dialogue serves as a gameplay mechanic. If he sounds like he's right outside the door, he probably is.
The Strategy for Night 6
If you’re trying to beat the "Impossible Night," you need to master the camera-to-office transition. You can't spend more than two seconds on the cameras. Check 39's location, locate the plushie, and immediately pull the monitor down.
- Keep your cursor near the center of the screen to catch the nose boop.
- Listen for the specific "laugh" that indicates a room change.
- Don't panic when he starts swearing; it’s a distraction technique.
The Legacy of the Green Bunny
Why are we still talking about Five Nights at 39s in 2026?
Mainly because it represents a turning point in fan game history. Before 39, most fan games were trying to be "scarier" than the original. They wanted more blood, darker halls, and louder screams. 39Games went the opposite direction. By making the game a comedy-horror hybrid, they carved out a niche that hadn't been explored yet.

It paved the way for other "joke" games that actually had competent mechanics. It proved that you could take the FNaF engine and do something completely different with it. You didn't have to be a clone; you could be a caricature.
Actionable Tips for New Players
If you're jumping into Five Nights at 39s for the first time, keep these points in mind to avoid a quick game over:
Watch the Plushie, Not Just the Bunny
The biggest mistake beginners make is focusing entirely on 39's movement in the halls. The plushie on your desk is a silent killer. Make it a habit to click it every time you close the camera feed.
Learn the Audio Cues
39 talks constantly. While it might seem like random flavor text, his distance is reflected in the volume and panning of the audio. Using headphones isn't just recommended; it’s basically required for the later nights.
Don't Over-Click
When 39 gets into the office, you need to click his nose. However, spam-clicking can sometimes cause the game to miss the hit registration if you aren't precise. One well-timed click is better than ten frantic ones.
Manage Your Stress
The game is designed to annoy you. The flashing lights and the constant shouting are meant to make you mess up your rhythm. If you find yourself getting frustrated, take a break. The mechanics are simple, but they require a calm hand to execute when the AI is at level 20.
Five Nights at 39s remains a fascinating piece of gaming history. It’s a reminder of a time when the internet was obsessed with a specific brand of animatronic horror and wasn't afraid to poke fun at itself. Whether you love the humor or hate it, the game’s impact on the Game Jolt community is undeniable. It stands as one of the most downloaded fan games for a reason—it’s memorable. In a sea of generic Freddy clones, the swearing green rabbit is impossible to forget.
