Sawada created one of these event courses himself, called “Super Mario Kun 25th Anniversary,” in commemoration of the anniversary of the manga, and as a reward to his fans. Super Mario Maker players should definitely give the course a try after installing the update, because you’ll get rewarded with the Super Mario Kun Mystery Mushroom costume.
In addition to adding checkpoints to courses, players can also add stackable power-ups that’ll have different effects on Mario in succession, just like real Mario games. For instance, if you attach a Super Mushroom to a Fire Flower and place it in a block, Mario will get the mushroom when he’s small and the flower when he’s big.
The update is live to install for Super Mario Maker now. Be sure to grab that Super Mario-Kun costume!
