Mascots[]
Kang No-eul[]

No-eul, partially costumed.
A North Korean defector who had left her daughter behind in her escape, No-eul began working at the park as a mascot in 2021 or 2022 to fund the search for her daughter. She worked in the bunny costume. After two years on the job, she accepted an offer in 2024 to serve as a guard in the upcoming 37th Squid Game. On her sudden resignation, her employer chastised her for not announcing this earlier as it would be hard to find a replacement. When a colleague, who had taken her place as the bunny mascot, asked her to join them for drinks, she ignored him. After her departure, the colleague described her as "cold".
Pig Mascot[]

The pig mascot
The unnamed pig mascot was an employee who wore the pig costume. He detested wearing the costumes. He entered the break room with his costume's 'head' off and began spewing expletives, unaware that Park Na-yeon had sneaked in. After noticing her, he quickly put the 'head' back on in an attempt to calm her down until her father arrived and took her away.
After Na-yeon was taken away, a colleague of his asked who Na-yeon was and he informed her that Na-yeon was the cancer-stricken daughter of one of the park's artists.
On No-eul's resignation, he was swapped to the bunny costume, which he found to be even more uncomfortable. He invited her to come along with their colleagues to go out for drinks, to which she ignored him. He appeared to be on friendly terms with his employer as he casually derided the experience of wearing the costumes in front of him. He also described No-eul as "cold" and the employer agreed.
He is played by actor Jo Suk-in.
Blue Mascot[]
Who is she?

The blue mascot
This unnamed mascot was an employee who wore a costume of a character wearing blue.
She had been resting in the break room with her costume's 'head' off as several of her colleagues entered the room. She agreed to going out to get some drinks after work at a newly-opened establishedment located near the park. Soon after, a little girl snuck in to the break room, which prompted her and the rest of the mascots to put their 'heads' back on. She watched as the girl approached No-eul, the bunny mascot, to gift a drawing. However, her colleague in the pig costume suddenly entered the break room cursing and swearing with his 'head' off, which caused the little girl to start crying. Her father then appeared and took her away.
When her colleague in the pig costume remarked that he was surprised that the girl was out of the hospital, she asked him who she was. Her colleague informed her that the girl was the daughter of one of the park's artists and that she had blood cancer and was awaiting a bone marrow transplant.
She is portrayed by actress Jo A-young.

This unnamed mascot was an employee who wore a Jester costume.
As he entered the break room with his Jester har off, he complained about how weak the room's air conditioning was, upset as he had spent a long while out in the hot weather in the costume, wondering when the air conditioning in the room would be fixed. He and his colleagues agreed to go out for drinks after work at a newly-opened established located near the park, as they were not busy after work. He then remarked on how exhausted he was.
However, a little girl then snuck in to the break room. This prompted him to put his Jester hat back on and go back to acting.

Several performers in the Mardis Gras Parade.
The amusement parks had several other mascots, including a tiger mascot, an elf mascot, a mascot wearing a green dress and a mascot wearing a pink dress. They were present in the break room before Na-yeon entered. There was also a cape-wearing mascot who entered the break room along with the pig mascot.
There are also several mascots who are seen in the parade but not in the break room, including several women donned in festive wear at either side of the parade vehicles, several people wearing clown makeup, a woman dressed in a purple outfit walking alongside a vehicle, and a woman and a man wearing striped outfits on the parade vehicle on either side of the elf.
None of them appear to have had lines, at least in the final cut, and all of them, save for two who were portrayed by actors Jang Geon-hee and Ahn Yoon-jung credited as "Puppetry staff", appear to have been played by extras who were not credited.
Potrait painters[]
Park Gyeong-seok[]

Gyeong-seok painting a portrait
Park Gyeong-seok worked as a portrait painter at the park. As a single father, he brought his cancer-stricken daughter, Na-yeon, along with him to work, although he presumably allowed her to wander around the park, on the condition that she not venture into areas that she was not allowed in.
When Na-yeon had snuck into the break room to give the bunny mascot a drawing, he dashed in and retrieved her, chastising her for running off. However, she soon fell unconscious while at the park and he followed her in the ambulance to the hospital, directing the paramedics to a specific hospital that she had previously been taken to.
He presumably quit his job at the park in order to enter the Squid Games, hopefully win and pay for her medication.
Other painters[]

The portrait painters
The park employed at least five other portrait painters, all of whom were seen seated to the right of Gyeong-seok painting portraits of visitors.
None of them had lines and all were portrayed by extras who were not credited.
