Level 4-4 (Mario vs. Donkey Kong: Tipping Stars)
From the Super Mario Wiki
The course is a wide arrangement of pathways with Movable Pipes, Red Girders, and High Springs. Mini Mario starts in the left half of the stage, on the bottom floor. On the platforms surrounding a pipe on the ceiling are a Mini Peach and a Mini Toad, trapped in capsules. The Mini Mario should reach and free them from the capsules, then head for their assigned Goal Doors located mostly in the right half of the course. Mini Mario's door is located on the bottom floor, while the other are located higher up on a platform with gray girders.
The M Coin is found between Mini Toad's and Mini Peach's doors, standing closer to the latter. To collect it, the player needs to place a High Spring under the platform with the coin and have the Minis bounce from it in the correct direction.
The following data applies in both the Nintendo 3DS and the Wii U versions of the game.
