In addition to the ability to create checkpoints, one of the biggest features added in Super Mario Maker’s recent update was the launch of Event Courses. This feature allows Nintendo to promote courses created with different partners, one of which is Yukio Sawada, creator of the Super Mario Kun manga series.
The level, titled “Super Mario Kun 25th Anniversary” was created by Sawada himself as a way to celebrate the anniversary of the manga and give thanks to fans. In addition to the course itself, users will receive another gift upon its completion: the Super Mario Kun costume. Although the manga may not be widely familiar, this Event Course and costume are available globally, and the official video for them can be found below.
