Which idol duo appears in Splatoon?

The idol duo in Splatoon is the Squid Sisters. The pair consists of Callie and Marie, cousins who became famous performers and presenters in Inkopolis.

They first appeared in the original Splatoon for Wii U, where they hosted the in-game news and announced stage rotations, Splatfests, and other events. Their music, including “Calamari Inkantation,” is part of Splatoon’s fictional world and soundtrack.

Players sometimes confuse the Squid Sisters with Off the Hook or Deep Cut. Off the Hook—Pearl and Marina—are the featured duo in Splatoon 2, while Deep Cut—Shiver, Frye, and Big Man—are the idol group introduced in Splatoon 3. Callie and Marie remain important characters across the series, appearing in later campaigns and performances.
