An image of a Jack-o'-Burger found in Level 4.


Jack-o'-Burgers are large pumpkins with no stems cut in half. In between the two halves, each Jack-o'-Burger is filled with ingredients similar to what can be found in burgers in The Frontrooms. They can be found in almost every single Level of the backrooms, but are most commonly found in Levels which naturally contain food (e.g. Level 6.1.) They are also found very frequently during the month of October.1 Over 4,700+ Jack-o'-Burgers have been found since 2007.

Upon consumption of a Jack-o'-Burger, the wanderer will begin to feel very stuffed and sleepy. They will then have severe hallucinations for 30-90 minutes before falling asleep for 4-6 hours. It is not recommended to consume a Jack-o'-Burger unless the wanderer is starving to death, because while they sleep they are susceptible to entity attacks and are unable to run or protect themselves.


Jack-o'-Burgers are sentient and fully aware. After keeping a Jack-o'-Burger in one's arms for more than 15 minutes, it will start whispering to the wanderer holding it. Over time, it will slowly get louder and louder until it is talking at a normal volume and having full conversations. It appears to send messages directly to the wanderer's mind and communicate with their thoughts, as you do not need to speak out loud to talk to a Jack-o'-Burger. It is unknown if they have full access to wanderer's thoughts. When holding a Jack-o'-Burger, wanderers have sort of described it like "Hearing a voice in their head speak to them." A wanderer can either communicate directly through their thoughts to the Jack-o'-Burger or they can just talk out loud and the Jack-o'-Burger will respond (most of the time).

Jack-o'-Burgers are also quite intelligent, with the average IQ of a Jack-o'-Burger being around 125. Most of them are well-spoken, even if they are insulting you.

Different Jack-o'-Burgers have different personalities. If a Jack-o'-Burger contains a large amount of meat, it has a boastful personality and will talk only about itself and its 'achievements'. If a Jack-o'-Burger contains a large amount of cheese, it has a kind, empathetic and nice personality, and it will listen and have in-depth conversations with wanderers. If a Jack-o'-Burger contains a large amount of tomatoes, it has a bitter personality and will insult wanderers. If a Jack-o'-Burger contains a large amount of lettuce, it will be less inclined to talk and will exhibit an introverted-like behavior, but it will be more inclined to listen. It is possible to find Jack-o'-Burgers which have different or mixed personalities, but the ones listed above are the most common.

Jack-o'-Burgers, are known to communicate with one another when in close vicinity, even if they aren't touching. It is unknown if it is necessary for a human to touch a Jack-o'-Burger to communicate with it. If a wanderer is holding more than one Jack-o'-Burger or touching another wanderer at the same time, the Jack-o'-Burger(s) and the wanderer(s) can communicate to each other by a combination of speaking and telepathy.

Jack-o'-Burgers appear to identify as genderless, although some may sound more masculine or feminine than others.

While eating a Jack-o'-Burger, wanderers report hearing a faint scream every bite, although they cannot place where exactly the sound came from. Most wanderers that eat Jack-o'-Burgers have no idea that it is sentient.


Jack-o'-Burgers are most commonly about 12 inches or 30.4 centimeters in diameter, although slightly smaller and bigger variants have been found. Ingredients found within the pumpkin buns usually include a smeat patty, 7-16 leaves of lettuce, 4-9 slices of American cheese, and 5-13 slices of tomato. They can rarely have sesame seeds on the top pumpkin bun.2 They have no limbs and cannot move on their own.


The first known mention of a Jack-o'-Burger was found on a popular online chatroom application specifically for the backrooms, known as Backdoor. An archive of the conversation can be found here.
