Pearl's History
Pearl was born into an exceedingly rich family, something that came across in a lot of stories about her childhood, such as being able to easily afford top of the range musical equipment and receiving a ship identical to the Manta Maria for her sixth birthday. She also met the 'Lord of The Lake' who owns Piranha Pit. Pearl was interested in music from an early age, taking part in an Inkopolis Youth Folk-Singing Contest and causing some destruction with the power of her voice. Pearl later attempted to start a musical career of her own, and despite having little to no idea how to write music, she insisted her heart was in the right place. She eventually became known as a death metal singer, demonstrating a notably more vulgar side with her song #$@%* Dudes Be #$@%* Sleepin, which garnered some fans but never went beyond that.
While practicing her potentially dangerous voice on Mt. Nantai less than two years before the events of Splatoon 2, Pearl met Marina Ida, a newly defected Octoling, and the two quickly bonded. Pearl never learnt of Marina's past, believing her to be a "country bumpkin", and taught Marina the ways of Inkling society. After meeting each other again, the two eventually became friends, with Marina demonstrating her musical abilities with a demo of Ebb & Flow. After hearing this, Pearl agreed to form a band with her, which led to her fully establishing herself in the public consciousness upon the formation of Off the Hook. They released Ebb & Flow as their first single, and it was a hit. By the time of their fourth single, around nine months after the events of Splatoon, they had become popular enough to take over hosting Inkopolis News from the Squid Sisters.
Splatoon 2
By the time of Splatoon 2, Off the Hook had become famous in Inkopolis Square for their music and for presenting Inkopolis News, in which Pearl had a similar relationship with Marina as Callie had with Marie. Their work included hosting Splatfest events, announcing the themes and singing and dancing to Color Pulse for the event's duration. Although Pearl and Marina did not make appearances during Octo Canyon, they were the first to break the news of Callie and the Great Zapfish's disappearances. They also announced their rescue on Inkopolis News, fulfilling a request to play Fresh Start over the credits.
Octo Expansion
When the game starts up the first time in the 3.1.0. update, Pearl will put an Inkopolis Fashion Focus about a trend of "squidkids with weird hairstyles" which are actually Octolings. As the broadcast ends, Pearl says that that was the only best thing so she'll probably never do it again.
Off the Hook makes an appearance helping Agent 8 and Cap'n Cuttlefish by giving advice and commentary on Agent 8's tests. They meet the duo after Agent 8 passes Fake Plastic Station through Cap'n Cuttlefish's walkie-talkie as they were on Mount Nantai where the signal was the strongest, and Pearl and Marina call themselves MC. Princess and DJ_Hyperfresh respectively. If Agent 8 loses all of their lives in a test at least twice, Marina will offer to use Agent 8's test data and hack the Kamabo Corporation's data base to trick the test into thinking Agent 8 passed. If Agent 8 has less than 100 CQ Points, then Pearl will take money from her dad's wallet and Marina will transfer them into CQ Points.
After Agent 8 collects all the Thangs, Marina discovers it makes a blender and the Telephone that had them find the Thangs is intent on actually blending Agent 8 and Cap'n Cuttlefish into raw material. Before it can do so, however, Marina activates Agent 8's CQ-80's distress signal, summoning Agent 3 and breaking the blender and phone in the nick of time. Marina then sees an unconscious Agent 3's employee model of the CQ-80 and tells Agent 8 that they can escape through the hole Agent 3 made. As Agent 8 escapes the facility, Off the Hook shows up with a fleet of helicopters to pick them up along with Cap'n Cuttlefish and Agent 3.
As Pearl raps with Cap'n Cuttlefish again, the platform Agent 8 was on rises up and turns out to be a statue with the phone now known as Commander Tartar intending on destroying all Inklings and Octolings with his blast of primordial ooze. Marina analyzes the statue and discovers that the statue is charging up via sunlight. If they can cover it with ink with the help of her prototype Hyperbombs that Agent 8 has to manually detonate, then the statue will stop charging, and Pearl will then finish it off with a "Hypersonic Scream" to destroy the statue, but they have to do so within three minutes, or Tartar will destroy Inkopolis.
After Agent 8 detonates them all, the statue is going to fire anyway, prompting Pearl to drop onto the platform below the helicopter and activate her Special, a giant Killer Wail stylized with her crown. As the statue fires, Pearl lets out a giant "Booyah" and battles with the statue's blast before pushing it back and destroying the whole statue with pink ink, along with Tartar, who's last words are telling the professor who created it that their reunion beckons before perishing. As the statue now collapses into the sea, Pearl and Marina celebrate with Cuttlefish, Agent 8, and a recovered Agent 3, and then watch the credits.
Splatoon 3
Pearl, alongside Marina returns in Splatoon 3, after scouting for new members while on a tour, they reformed as a new band named Damp Socks feat. Off the Hook.
