Level 1-4 (Mario vs. Donkey Kong: Tipping Stars)
From the Super Mario Wiki
Level 1-4 is the fourth course in Rolling Hills in Mario vs. Donkey Kong: Tipping Stars. It is the first Multi-Door level in the game and, as such, introduces the concept of bringing different Minis to their respective Goal Doors after freeing them from capsules. Pipes can be used here for the first time in the game.
Mini Mario begins beside Mini Peach's door and heads towards a pipe leading downward. To the left, after a slope, lies Mini Peach inside a capsule. Once Mini Mario rescues Mini Peach, they have to be led with Red Girders towards a Split Pipe that warps them at the top of the stage. Continuing their march, they eventually arrive at their respective doors.
The M Coin is seen left from Mini Peach's initial position. The player should simply draw a Red Girder bridge from here to a rivet located next to the coin, allowing the Minis to reach and collect it.
The following data applies in both the Nintendo 3DS and the Wii U versions of the game.
