Over in Japan, there's a fun Splatoon tournament rolling across the country. Teams have been going at it for a couple of days with the final matches taking place on January 30. The Splatoon Koshien Finals can be viewed live via NicoNico.

During the finals, however, will be a special broadcast concert featuring the Squid Sisters. Callie and Marie will appear on stage as holograms singing some of the game's catchiest tunes. It's cool Nintendo is putting on this show. It's a celebration of Splatoon's achievements in less than a year on the market.

Check out some of the musicians warming up as well as a sneak peak of the girls in the announcement video below:
