All Mini Marios start in the bottom left part of the course. The Key Mini Mario starts behind one of the other Mini Marios at the bottom, while the third Mini Mario starts on a platform right above them. The course has a tall layout and, aside from Pink Blocks, contains several Yellow Springs and Split Pipes that can be used to reach upper platforms. Using these elements, the minis have to be guided to the Goal Door located on a girder platform just above the toys, also on the left side. The Key Mini Mario should be brought to the door first to unlock it, followed by the other two minis.
Mini Mario Card
The Mini Mario Card is near the top right of the course, on a girder that also contains a Yellow Spring. Guided by Pink Blocks, the minis can use several Yellow Springs and a yellow Split Pipe to reach and collect the card.
The M-Token is at the top of the course, on the edge of a spike trap. Once they reach the top portion of the course, the minis can be guided to the token with Pink Blocks, but there should be a gap in the Pink Block formation right under the token to prevent the toys from walking to the spikes.
