- Were you maybe looking for Toy Bonnie or Shadow Bonnie from the second game, or perhaps Springtrapfrom the third game?
|“||...these characters hold a special place in the hearts of children, and we need to show them a little respect, okay?||”|
|— Phone Guy, Night 1|
|Known as||Bonnie the Bunny|
|Occupation||Guitarist in the Freddy Fazbear's Pizzeria Band|
|First appearance||Night 1|
However, at night, he acts as the other animatronics do: hunting down any human in the area and forcefully stuffing them into a Freddy Fazbear suit, killing them.
Bonnie is a lavender-colored rabbit animatronic, with maroon eyes. He has articulated ears that can bend forward, and wears a red bow tie which is partially obstructed by his chin. Onstage, he carries an orange guitar. Unlike the other characters, he has rounded teeth, and does not have eyebrows.
Excluding his head, the majority of Bonnie's body appears identical to Freddy's, apart from the latter's color. This version of Bonnie, like most of the animatronics in the first game, seems to have no teeth on his upper jaw.
Bonnie's starting location is the Show Stage, along with his bandmates, Freddy and Chica. Upon activation, he will move to any room on the left side of the restaurant, excluding Pirate Cove. This means he can appear in the Dining Area, Backstage, the West Hall, the Supply Closet, and the West Hall Corner. When looking into The Office, he appears leaning into the left doorway from the blind spot directly behind the left door.
Bonnie is known for coming and returning to The Office more frequently than the other animatronics, and, like Foxy, he only approaches from the left side, though their similarities end there. He will stare through the doorway into The Office, unlike Chica, who looks through the window. The frequency with which Bonnie approaches The Office appears to be due to supposed teleportation abilities, which is noticeable with Cheat Mode enabled. Bonnie is also capable of temporarily disabling the cameras as he moves to another area, as does Chica.
On some nights, if the player does not look at Bonnie on the Show Stage, he will not move from that location. Although this is one of the best methods for surviving after Night 2, using this method leaves the player unable to check on Pirate Cove (as the Show Stage is the default camera when opening the Monitor), leaving the player vulnerable to an attack from Foxy.
On the 4th, 5th, 6th, and 7th nights, while standing in front of the camera outside The Office (CAM 2B), Bonnie's head and jaw twitch violently in a very paranormal manner. The Robotvoice sound byte can be heard while he is twitching, even if the player is not looking at him directly on the Monitor. These paranormal behaviors are also exhibited by Chica. On any night, he may be seen standing a few inches away from the Backstage camera (CAM 5), staring directly into it. His eyes are completely black, save for white, pinprick-sized pupils.
When Bonnie enters The Office while the player is viewing the cameras, quiet, raspy, groan-like noises are audible. Once the player lowers the camera view and returns to The Office, Bonnie will attack them and cause a game over. The same noises can also be heard in this situation if Chica is waiting to attack. Bonnie and Chica are capable of forcing the player to lower the Monitor in order to attack, meaning the player cannot necessarily survive by continuing to view the Monitor until 6 AM as previously thought.
The groaning sounds made by Bonnie when he sneaks into The Office. Interestingly, Chica makes the same sounds. The sound Bonnie makes when attacking the player. Each animatronic (excluding Golden Freddy) makes a noise identical to this in the same circumstance. Warning: Loud! The noise Bonnie makes when moving from one room to another. Chica also makes this noise while moving. Freddy also happens to emit this noise, but only after the power has been fully drained. 
- Bonnie is usually the first animatronic to move and approach the player's doors.
Bonnie is often mistaken as a female. This is proven false because ofScott Cawthon's confirmation.
- On Nights 1 to 3, Bonnie is more active than the other animatronics, as he is generally the first to leave the Show Stage.
- Interestingly, when Bonnie is in the Backstage, he seems to take no heed to the metal endoskeleton sitting on the table, which clearly lacks a suit. Though Phone Guy claims the animatronics would put costumes on bare endoskeletons because it's supposedly "against the rules" to be without a suit, Bonnie doesn't acknowledge the endoskeleton backstage and obviously chooses to focus on the player, contradicting the former security guard's statements.
- However, this may be because the backstage area is full of spare parts, and, as such, a bare endoskeleton is not out of place there.
- In the trailer, Bonnie is shown running down the hallway. He was stripped of this ability in the final game, with Foxy taking on the role instead.
- In the trailer, Bonnie is shown to remove his face, revealing his endoskeleton. However, this never happens in-game.
- Bonnie might be loosely based on Mr. Munch from Chuck E. Cheese's, as both have purple fur, a lighter color on their stomachs, and a somewhat larger girth than the other characters.
- He also might be based on Jasper T. Jowls, as they both are the guitarists in the band.
According to Scott Cawthon, Bonnie is the animatronic he finds to be the scariest, as he has had several nightmares about Bonnie while developing the game.
- Bonnie makes an abnormally human-like groaning sound when he enters The Office. What causes this is unknown, and it is unlikely that a robotic voice box would be capable of mimicking organic wheezing noises, even if the voice box was damaged. This may coincide with the possibility that the robots are haunted, and some unknown, paranormal source is making these noises. It may also fit in with the theory that a person is stuffed in the animatronics, though this is very unlikely, for the person would either have already been removed or killed by the internal mechanics of the suit.
- Chica makes these same noises when inside of The Office.
- On very rare occasions, after the Game Over screen is displayed, or when starting up the game, a full-screen image of an eyeless Bonnie (the same seen in hallucinations) can sometimes appear. The image stays for approximately ten seconds until white pupils suddenly appear. After one more second passes, the game returns to the main menu. This is also true for the mobile version.
- There is a glitch that allows the player to survive while Bonnie attacks. If the player raises the Monitor quickly, Bonnie's scream will repeat and his kill animation is prolonged, delaying a Game Over. Seethis video. This glitch can also work with Chica.
- There is a glitch where the player can be killed by Bonnie, but he doesn't appear physically and the player can only hear his scream. Watch this video.
- It appears as if Bonnie may be partially in The Office already when located outside the left door.
- Bonnie catches unsuspecting beginners off-guard, as he often appears first and more frequently than the other animatronics.
- According to an interview with Scott Cawthon, Bonnie was the first animatronic that was added to the game.
- Bonnie had no animation when killing the player at the time, as it was only a still image.
- Unlike the other animatronics in the first game, Bonnie has no eyebrows.
- In the third game's teaser trailer, one scene appears to feature a Bonnie-themed arcade cabinet with a flashing blue light.
- There is also a drawing in the first part of the trailer that appears to feature an unusual-looking Bonnie.
- Also in the third game's trailer, during a shot where the camera pans past the three main animatronics, Bonnie can be seen moving his eye to look at the camera.
- On any night, when Bonnie is in the Backstage room, the player can cause the game to change to the close-up of his face by simply lowering and raising the Monitor. Switching to any other room before doing so will cause the scene to not switch.
- It is noticable that when Freddy stares at the camera on the Show Stage, flipping to the Backstage camera reveals Bonnie staring at the camera as well.
