With the release of Super Mario Maker 3DS imminent, it seems that Nintendo is going to continue to support the game with new content. Their are currently 150 mystery mushroom costumes available with the latest one featuring Undo Dog. Like usual the new skin for 8-bit Mario can be unlocked by completing the matching event course.
Undo Dog is the cute puppy that, well, undoes your mistakes. He originally appeared in Mario Paint and can be found in Super Mario Maker zooming around on his rocket.
It’s nice to see Nintendo’s flagship game design platform continue to get attention. However, since the 3DS port doesn’t contain the costumes, it’s strange that they’re releasing so close to that handheld launch. Either way, it’s always nice seeing more characters and it makes me hopeful that Super Mario Maker will get more substantial additions further down the line, especially with that rumored Switch port supposedly on the way.
