Level 4-1 (Mario vs. Donkey Kong: Tipping Stars)
From the Super Mario Wiki
Level 4-1 is the first course of Crumbling Cavern in Mario vs. Donkey Kong: Tipping Stars. It introduces Movable Pipes, a pair of pipes that lead to each other and can be repositioned conveniently in designated outlines. In this regard, the level is analogous to Area 4-1 from Mario vs. Donkey Kong: Mini-Land Mayhem!.
The level features two Mini Marios.
There are four Movable Pipe outlines placed at different corners of the course, leading to various platforms mixed with Red Girder Rivets. The two Minis start on the middle floor, facing different directions. With the help of Red Girders and Movable Pipes, the player needs to lead them to the Goal Door, located at the top left.
The M Coin is above an horizontal Movable Pipe outline in the bottom right, stretching over a pit of spikes. The path that the Minis have to follow to get there consists of a short tunnel on the top right, leading down towards a slope. There is also a trail of gold Coins before the M Coin. The pipe should be turned solid in order to have the Minis walk on it and reach the M Coin, avoiding the spikes underneath.
