Mario starts off on some non-moving ground where he must go left onto a Conveyor Belt. A Dōryī can be found on the other side spitting seeds at Mario, which must be dodged to avoid being defeated. Crouching to avoid the seeds will have him being moved back, while jumping will get him over the seeds, but he will have to keep running to not get moved back. Once at the end of the Conveyor Belt, he must avoid getting shot again, then climb up the ropes to the top, where the key can be found on a single platform. Mario must grab the key while watching out for a Dōryī, which is on another platform, where it can shoot Mario when he's on top of the key. He then must take the key over to the door while watching out for the Kurasshā which will crush him. Once past the Kurasshā, Mario must simply take the key to the door to end the level.
