The Squid Sisters (Sea O' Colors シオカラーズ Shiokarāzu in Japan) are an idol duo from the Splatoon universe.
The Squid Sisters are a fashionable Inkling idol group in Inkopolis, consisting of Callie and Marie. They were the former hosts for the Inkopolis News program, which announces events, new DLC and other battle-related news. They used to host and manage Splatfests. Despite their stage name, the duo are actually cousins.
The Squid Sisters appear as an Assist Trophy. When summoned, the sisters preform a song, causing the camera to zoom in and focus directly on them. This causes the field of view to become extremely small, shortening the range of the blast lines, making it easier to be KOd.
