Pest enters the elevator, saying: "こんにちは ! 今日は素敵な日です。", what with It roughly translates to "Hello! It's a beautiful day today." This dialogue changes to "Pest" if Pub is in the elevator when he enters. In this case, the phrase translates to "My day gets worse every time I see you." He can steal coins if the player is close enough to him, or if the player annoys him enough by repeatedly spraying him. The amount of coins stolen depends on the victim's coin count, and Pest can steal up to 5-10 coins. The name "Pest" may be a double meaning, both short for PartyGuest and a reference to insects as pests, as he is part beetle. Pest has always been part beetle. Even though he is part beetle, he only has a partial exoskeleton. It wasn't designed to resemble any particular beetle, but it does resemble a stag beetle. He has four eyes and he sees perfectly. Its jaws are sharp and it can grab objects with them. He can also fight with them. He can lift 1,141 times his own weight. It may hiss, crackle, make buzzing sounds, and possibly purr. Pest speaks three languages: English, Japanese, and Bug. His native language is beetle. He learned other languages ​​to better communicate with people. Pest knows the Pub wants to be his friend, but he doesn't like them. He finds the Pub generally irritating and sees no point in talking to them. If Pest and Pub had fought, Pest would have easily won. Pest finds it unusual that Bloxie is Pub's favorite drink.

Pest has a P6 model reminiscent of a 2011 Roblox guest. His face texture depicts a sly grin with two sharp red eyes and red accent lines under and above them, creating the impression of slight bags under his eyes and brow furrows. He has beetle-like horns on his head, and mandibles protruding from his mouth. His teeth are sharp and white, visible when he smirks. All parts of his body are black, with a black shadow on the top of his head. On the front of his upper body is the word "Regret" in Japanese hiragana (こうかいする, Kō kai suru), and on the back of his torso are the words "Do you regret your decision?" (also in Japanese) (自分の決断を復悔していますか？). On his left arm are the red numbers "1314" vertically. He also wears a modified version of the classic Roblox baseball cap, with the R slightly rotated to the right and replaced with a P. if the player is close enough to him, or if the player harasses him enough by repeatedly spraying him. The number of coins stolen depends on the victim's coin count, and Pest can steal up to 5-10 coins. Personality-wise, Pest acts aloof and cold towards other NPCs, which tends to frustrate more sensitive characters. He's a loner and doesn't want to make friends, though he often denies this when it's mentioned. He's easily irritated, blunt, and often steals items and lies about it when asked if he knows where they went. Pest speaks Japanese, which he often uses to insult other NPCs so they won't understand what he's saying. Despite this, he can also have a softer side. If the vacuum cleaner approaches Pest, he will pick it up and put it in his pocket. This only applies to regular vacuum cleaners. Pest's dialogue when he gets sprayed 40 times from the spray bottle may be a reference to the "For What Purpose" meme.

It was also hinted that Pub's happy attitude is a defense mechanism triggered by something they've witnessed. If Mr. R is in an elevator on the underground station floor, Pub will stop and frown in front of the elevator door, step out onto the tracks, and be killed by the train. Oddly, when Pub holds a gift, they don't have a walking animation. Instead, they enter the elevator in their idle pose. MR can't burn Pub when he turns off the lights. Pub has a birthday every day. It's just a birthday in spirit, they don't get old with every holiday. Pub lives in Happy Home Party. According to a conversation with Pilby, Pub doesn't mind having his apartment blown up, as they say it "adds excitement." Pub used to frown when players started destroying their apartment. They don't mind those creepy eyes in their apartment, as it keeps the rent down. Pub has an injury from constantly being hit by random people in the elevator. They have trauma from something else, but it is deeply repressed and they do not remember it. There's a chance they might have a breakdown at some point. The worst thing the Pub did was watch the sacrifice without doing anything. There is someone who wants to kill Pub. It might be Follie, as she mentioned in one of the dialogues that she should stalk him. The Pub is protected by the same spirit that controls MR. They don't suspect that they are constantly in danger and that they are being protected. Pub likes Pest, but Pest doesn't like Pub. If they had not bothered Pest, Pest would not have bothered them.

Pub looks like a stereotypical Roblox noob. They have a yellow head and arms, a blue torso, and green legs. However, Pub's color palette is inaccurate compared to standard Roblox noobs, as their legs are dark green rather than yellowish-green. They also have a distinctive ":3" face, a purple hat with multicolored stars on it, and a horn that can be any color, but most official renders depict it as red. Pub has been officially stated to be bald, like all characters without visible hair. Pub is a happy Robloxian with a love of parties and a borderline obsession with them. Much of their dialogue revolves around parties, birthdays, or anything related to these topics. They appear somewhat childish and silly, and tend to be oblivious and naive to the world around them. Their constant happiness irritates more serious or grumpy NPCs, especially Gnarpy and Pest. Despite their silly and unassuming demeanor, they seem to be somehow connected to the MP, albeit unwittingly: meteors emanating from the MP on the Happy Home Party floor don't fall if Pub is in the elevator, and Pub can't be killed by the MP.

Despite their silly and unassuming demeanor, they seem to have some sort of connection to the MR, albeit unwittingly: meteors emanating from the MR on the Happy Home Party floor do not fall if Pub is in the elevator, and Pub cannot be killed by the MR.

MP is a light gray, clay-like stone with oval-shaped eyes, a dot on his forehead, and a wide smile. One in-game tip states that "MP is not alive." This could mean that MR is actually a ghost. The advertising banner on the Happy Home Party floor has graffiti that hints at MP being a fallen god. The name MRa is pronounced "Mister". MR's birthday is 0/0, that is, a non-existent day. MPa is three feet tall (but it is also SUGGESTED that MPa is the size and height of a basketball). MR is the cause of meteorites falling on the Happy Home Party floor. This event is caused by the spirit that controls MPa. MR is a stone possessed by a spirit/god. It seems like MR has a list of crimes These crimes are: Murder. Blackmail. Intimidation. Aggravated assault. Drunk driving. And so on, there are many more of them.

NULL appears as a yellow-skinned Robloxian, wearing a gray hoodie with black drawstrings, red entrails, and a hood pulled over the back of his head. He also wears gray pants with large pockets, also red-lined. On his head is a yellow cap/hood with a red chicken comb, large black button eyes, and a shiny orange beak at the top and bottom of the opening. The cap is a modified version of Telamon's cap. The only visible part of his face is a pair of glowing eyes. He has no mouth. NULL is a robotic assistant controlled by a hybrid mind and refers to himself using the pronoun "we." He speaks eloquently and cryptically, often confusing other NPCs. He often speaks of "Prime" and references ascension, as well as the Greek figure known as Icarus, which is part of his undisclosed plan. It's currently unknown what this plan is. He works alongside Folly and MR, though he often clashes with the former. Likely due to his nature as a robot created to serve, NULL is very focused on fully utilizing his potential; therefore, he judges and dislikes other characters who, in his view, aren't fully utilizing their potential. NULL has been described by Yeucc as a "strange AI demon." According to the interaction between Melanie and Pest, NULL works for MR and has "strange powers". The latter may refer to his abilities, which are similar to builder's tools. NULL - aroeys. NULL has no age. NULL may like cards, as before he was removed, he looked like he was "walking" out of the way towards people playing a card game. NULL - "Helperbot," as entering the code from the Speedway toolbox on YouTube shows NULL, which is displayed in terrible quality. According to Yeucc's stream, NULL has a mouth, but its lips are closed, making it impossible to see. If NULL tried to eat fried chicken, he would only be able to rub it all over his face. Despite this fact, NULL's favorite drink is vegetable oil.

Appearance Follie wears a white turtleneck, black boots, and a white beret. Her legs are black, with red-tinted eyes. The dark shape of her head resembles spiky black hair. She also wears a white wooden mask with a diamond-shaped "eye" carved into it, but the mask is shattered, leaving only half of the right side. On the left side of her face is a brightly glowing red eye with red eyelashes and a pupil consisting of two yellow rings. The tips of her clawed fingers have a bright red gradient. Due to her tall stature, Follie looks down at the player when interacting with them.

As depicted in the official minicomic The Cleave, Folley has three red cuts on her stomach, similar to those seen on the Great One in Eternal Limbo, but not visible in-game due to her sweater completely obscuring them. Folley dislikes her clothes, especially her beret (as it reminds her of the betrayal of the Great One, the very being who created her), and typically reacts negatively when it comes up. Her clothes are "chained" to her. The Cleave describes her clothes as the "will" of the Great One: the beret allows her to think, the clothes allow her to feel, and the mask allows her to see. Folley is very cruel and often fantasizes about killing other NPCs or mentions traumatic events that happened to them in her dialogue. Folley also has ties to MR and NULL, quarreling with the latter, though it is implied that this is less out of genuine affection for MR and NULL than because she wants something from them. Folley also possesses the ability to invade others' dreams, using this ability to forcibly gather information from others and feed on the fear in their minds. Folley can possess others' bodies, but prefers not to, as it's usually useless for her situation. By her own account, she's made of malice. Folley rejects all attempts at compassion and refuses almost all items given to her.
