Level 6-6 (Mario vs. Donkey Kong: Tipping Stars)
From the Super Mario Wiki
The level is broad, encompassing Cannons and series of Pink Block spaces that form links between platforms. There are two pairs of Split Pipes in the right half area that lead from the bottom of the stage to the upper platforms. A Mini Mario and three Mini Toads start in an open space at the top left, while the other two Minis start on the lower grounds. Although the Goal Door is located closely at the bottom left, it is separated from the Minis by a high wall with an opening. To access the door, the Minis should be shot in that opening from the rightmost Cannon, located next to a cluster of Pink Block spaces.
The M Coin is located left from a wall of four Pink Block spaces near the bottom of the stage. To reach the coin, the Minis have to be shot diagonally from the Cannon near the Goal Door, using Pink Blocks to orient the toys correctly to the coin.
The following data applies in both the Nintendo 3DS and the Wii U versions of the game.
