What is the name of Pearl and Marina's pop music duo?

Pearl and Marina’s pop music duo is called Off the Hook.

The duo appears in Splatoon 2 as the resident idol act of Inkopolis Square. Pearl is an Inkling, while Marina is an Octoling, and their contrasting designs and personalities are central to the group’s appeal. They perform songs together and present news about stage rotations, events, and Splatfests, continuing the idol-and-broadcast tradition established by the Squid Sisters.

A frequent mix-up is confusing Off the Hook with the Squid Sisters or Deep Cut. The Squid Sisters—Callie and Marie—headline the first Splatoon, while Deep Cut—Shiver, Frye, and Big Man—hosts Splatoon 3’s Anarchy Splatcast. Off the Hook also returns in Splatoon 3’s Side Order expansion, where Marina’s technology and Pearl’s transformed role become important to the story. Their musical partnership is therefore tied to both Splatoon 2 and later expansion lore.
