Nintendo announced that it will debut a new costume set and Event Course for its popular level creator, Super Mario Maker, based on Japanese pop-metal band, Babymetal. The "Mystery Mushroom" costume will feature all three band members mashed together in unison. It's apparently the same basic sprite structure that we saw in December when a Mario & Luigi: Paper Jam mashup came to SMM, though obviously with a different skin and sound effects. Of course, this isn't the trio's first foray into video games. Their first single (and breakout hit), "Gimme Chocolate" made it into the a recent Rock Band 4 DLC.
