This is a request by  piotr182xx for Callie and Marie, the Squid Sisters, from the video game Splatoon franchise having a tickle fight. It appears that Marie is losing the fight, as Callie has captured Marie and tied to a pole. Marie is helpless to Callie's repeat tickle attacks.
Callie is a part of the Squid Sisters pop idol duo and a former host of Inkopolis News, along with her cousin Maria. Her signature color is magenta.

Callie was raised in Calamari County. At a young age, she became interested in singing and entered Inkopolis' first annual Youth Folk-Singing Contest with her cousin, Maria. Their stunning performance earned them a standing ovation from the audience, as well as a first place trophy and certificate. However, this success did not make them instant pop sensations. For a time after their move to Inkopolis, Callie and Marie struggled to make ends meet, and so worked part-time at Walleys Warehouse during their early years as professional singers. Callie also worked part-time at Piranha Pit.

Callie is very cheerful and excitable, and usually sports a grin on her face. She values her bond with her cousin Maria, the two having been inseparable since they were young. As children, they enjoyed star-gazing and playing tag together. She is particularly attentive to Marie's changes in mood, even noting when the latter wants to drink a latte based on expression alone. When by herself, however, Callie can become upset and prone to overthinking.

She is rather fond of puns, and uses them from time to time, a habit that tends to annoy her cousin. She is also optimistic and caring; in the Japanese version of Splatoon, she thanks her Splatfest team for doing their best, regardless of whether she won or not. Unlike Marie's sarcastic quips, Callie always seems to have something happy and innocent to say. She looks at the bright side of things while providing stage commentary. Her favourite Special seems to be the Bomb Rush.

Callie gravitates towards exciting outdoor activities, such as driving, running around, and going camping. She also loves art, decorating the Octarian underground with fabric and tape while under the influence of DJ Octavio's hypnoshades, and representing the discipline in the Art vs. Science Splatfest, though her drawings have been described cheekily by Marie as "avant-garde". She has expressed a fear of heights, ghosts, skateboarding, and even Bluefin Depot. She hates Flooders and spinning platforms, as she easily becomes motion sick, and cannot ride a bicycle or drive, which is ironic as she represented cars in the Cars vs, Planes Splatfest. Some of her Splatfest choices are energetic and uplifting – for example, her choices of Fit, Love and Perfect Body. She also loves to eat and often talks about food, much to the chagrin and occasional disgust of Marie. Her favorite food is chips. Easily distracted by cute, pretty, or striking things, many of her stage comments are about something completely irrelevant to the battle. Callie also seems to have a fascination with clothing and makeup.

In the Japanese version of Splatoon 2, Callie's speech while she is brainwashed is entirely rendered in katakana, like DJ Octavio. After Marie hits Callie with her low-tide ink, she begins to regain her ability to speak normally. During the Inkopolis Live concert at Tokaigi 2018, Callie briefly speaks in katakana as a joke.

Marie is a part of the Squid Sisters pop idol do and a host of Inkopolis News, alongside her cousin Callie. Her signature color is lime green.

Riding on the fame following her win at the Youth Folk-Singing Contest, Marie joined Callie in creating the Squid Sisters. Their repertoire includes a modern take on an ancient melody, a song unique to Splatfest, and a song used to defeat DJ Octavio. They have risen in notoriety, eventually becoming Inkopolis' premier pop icons, performing at Splatfests, and hosting Inkopolis News.

Over the course of the two years after the events of Splatoon, the Squid Sisters slowly drifted apart. Following the final Splatfest, they were rocketed to even greater fame as the biggest stars in Inkling society. However, after they released their first solo recordings, they began following separate paths. While Callie began making guest appearances on variety shows, Marie began putting on solo concerts, appearing on music shows, and even starting a career in theater. Their schedules allowed for little quality time spent together, but when they were together their relationship seemed to be intact. Unfortunately, Callie suddenly disappeared, which Marie discovered when she failed to show up for vacation back home in Calamari County. Fearful for what may have happened to her, Marie soon found that DJ Octavio had escaped his prison and moved to Inkopolis Square, where she hoped to find a new Inkling to help stop the Octarians as Agent 3 did in the past, taking a break from her career and going into hiding. Fortunately, no one in Inkopolis Square appears to know who she is.

Marie is seemingly quieter and not as excitable as her cousin, and usually only gives a half-smile, if at all. She can be a very sarcastic from time to time, and slightly prone to complaining, but is usually in a mild mood. Overall, her disposition is laid-back and friendly/grumpy. She is also an expert at doing impressions, as mentioned by Agent 1.

She dislikes overly-thrilling activities, and can even be somewhat lazy. She also doesn't seem to be a big fan of tomatoes.

She has shown a demonstrably more cheeky side, as seen in the POkemon Red vs. Pokemon Blue Splatfest ending dialogue, where Callie asked how to change the name of Marie’s Vulpix she traded her from “BLUEISBEST”, and Marie hurriedly ends the broadcast, slyly avoiding the question. In addition to this, when reattempting the final boss fight of Splatoon 2, at one point her dialogue reads: “Octavio, stop hitting yourself! Stop hitting yourself!”, having a laugh at the fact that you have to shoot DJ Octavio’s “fists” back at him.

When anticipating an announcement (for example, the theme of a Splatfest, or the contents of an update), she often repeats herself in excitement. (Ex. "What is it? What is it?!")

She mentions several times on Inkopolis News that her preferred weapon class is the Charger. Given the existence of the Hero Chrager Replica and her role as Agent 2, it is possible that Marie used a Charger in Octo Valley.

In Splatoon 2, she mentions that she is "more of a charger girl", and in the final battle, Tide Goes Out, she is shown using the Hero Charger.

Splatoon is a third-person shooter video game developed and published by Nintendo for the Wii U, which released worldwide in May 2015. The game centers around characters known as Inklings—beings that can transform between humanoid and squid forms, and hide or swim through colored ink sprayed on surfaces using gun, bucket, roller, or brush-based weaponry. Splatoon features several game modes, including 4-on-4 online multiplayer, and a single player campaign.

Splatoon was developed by Nintendo's Entertainment Analysis & Development division, and originated from a competitive multiplayer ink-based territory control game, which was later expanded to include squids and the ability to swim through ink. The concept was created by lead programmer Shintaro Sato, who had previously worked on games in the Animal Crossing franchise. The development team for Splatoon was generally composed of younger Nintendo employees compared to other titles by the company.

Splatoon received positive reviews upon its unveiling and release, with critics praising Nintendo's decision to enter the genre with a new franchise, the game's overall style and presentation, gameplay mechanics, and its soundtrack. Criticism was directed at the exclusion of voice chat and private lobbies, the small number of multiplayer maps at launch, and issues with online matchmaking. Nintendo provided extensive post-release support for the game by adding new maps and weapons to the game, adding a feature to allow users to create private lobbies and holding time-limited events called "Splatfests". Splatoon was awarded and nominated for several year-end accolades from several gaming publications. A sequel, Splatoon 2 was released for the Nintendo Switch in 2017.
