Level 6-8 (Mario vs. Donkey Kong: Tipping Stars)
From the Super Mario Wiki, the Mario encyclopedia
The level is composed of a large number of paths that intersect. It also contains sets of Pink Block slots, Movable Pipe outlines in all four corners and the center, and Red Girder Rivets, as well as a few columns of Rock between platforms.
After the Cursed Mini Mario starts moving, it drops to the bottom of the stage, walks on a spiked surface and some Pink Blocks, then enters a Movable Pipe that leads it back to its initial position. The other Minis are scattered throughout the course and are required to either use the Hammers at the top or the various slides in the level to attack and turn the Cursed Mini Mario back to normal. The Hammers are also necessary to destroy the Rock column that blocks the Goal Door at the left side of the stage.
The M Coin is standing above the Movable Pipe at the bottom right. To collect it, the toys should fall from an upper platform onto the pipe.
