The level features three Mini Marios, though not necessarily in the same starting positions.
The Mini Marios all begin between the bottom left and the bottom center, with the exit door near the top right. In order to reach it, they must simply be guided via a series of Long Springs, Green Pipes, and Cannons to it while avoiding Piranha Plants and a Snifit.
The M-Token is located near the middle right, suspended above a Spike Trap and below a Cannon. To collect it, the Mini Marios must bounce off of the next closest Long Spring from the left while headed right.
Mini Mario Card
The Mini Mario Card is located near the middle right, just below the exit door. The Mini Marios must fire diagonally from the Cannon near the M-Token and bounce off the Long Spring to reach it.
