Squid Sisters

Squid Sisters (Sea O' Colors シオカラーズ Shiokarāzu in Japan) are a pair of siblings from the Splatoon universe.

Character description
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.

In Super Smash Bros. Ultimate
The Squid Sisters appear as an Assist Trophy. When summoned, the sisters preform a song, causing the screen to zoom in and focus directly on them. This causes the field of view to become extremely small and make KOs easier to happen.
