Nintendo of Japan has announced that Babymetal are the next unlockable costume coming to Super Mario Maker, which is definitely something we can get behind.
Japanese rock band Babymetal are coming to Super Mario Maker
The members of Babymetal all move and jump as one, and their event course is due to drop today for Japanese Super Mario Maker players. The costume is only unlocked by beating that course, featured above.
It's not entirely clear if this will actually be released outside of Japan, but we sure hope so - Babymetal's recent appearance on The Late Show with Stephen Colbert certainly raised their profile in the west.
Babymetal released an announcement video on Nintendo Japan's official channel. If anyone can translate it, feel free to share in the comments.
If it has been a while since you jumped into Super Mario Maker, it's worth noting that the game has been updated with quite a lot of new content since launch.
