Ninji Speedruns

Ninji Speedruns is a special feature that was introduced with Version 2.0 in Super Mario Maker 2. The player must dash through one of three Nintendo-themed courses, with new courses being released every so often. One week after the level’s release, the player can race against a Ninji Ghost. If the player receives enough stamps on their stamp card, they can earn an outfit for their Mii.
