Super Mario Maker Callie and Marie costumes release next week.

Super Mario Maker continues adding content with costumes of the Squid Sisters, Callie and Marie. It's about frickin' time! Data miners found the costumes in an update to the game over a month ago, but Nintendo has chosen to make the announcement official on the heels of the final Splatfest reveal, in which players will choose between Callie and Marie.

It's nice to see the attention put into these costumes, and we're happy to see the squid form put to good use. Check out the trailer below, then tell us how you think the Squid Sisters stack up to the rest of the massive costume library.
