The level features three Mini Marios, though not necessarily in the same starting positions.
One Mini Mario begins at the very center while the other two begin at the bottom center, with the exit door near the top left. In order to reach it, they must simply be guided via a series of Cannons and Red Girders to it.
The M-Token is located near the bottom right, surrounded by Spike Traps. To collect it, a Mini Mario must simply fire left from the top right Cannon to ram into the Red Girder wall, then fire right from the next Cannon.
Mini Mario Card
The Mini Mario Card is located near the very center, just below the M-Token. A Mini Mario must simply fire left from the top right Cannon without hitting the Red Girder wall, then fire left from the next Cannon to reach it.
