Level B-19 is the third course in the Bonus 3 set and the nineteenth Bonus Level overall in Mario vs. Donkey Kong: Tipping Stars. It is set in Swirling Courtyard and is unlocked by earning 76 trophies.
The level contains many conveyors and rivets for Purple Conveyors while also featuring Split Pipes placed in different corners of the stage. The object of this level is to disable a few rows of color blocks that prevent access to the Goal Door at the bottom left. As the Minis walk around the level seeking Color Switches to disable these blocks, the player has to use conveyors to herd multiple Shy Guys in an indentation at the bottom of the stage, keeping them away from the Minis' path.
The two Mini Peaches start at the bottom of the stage. Soon after initiation, they enter a red Split Pipe which warps to the top left corner of the level, where the player needs to use Purple Conveyors to lead them onto a Blue Color Switch right below. Pressing it disables some blue blocks under a Shy Guy that prevents the Mini Luigi from moving forward, and drops the enemy onto a conveyor which should be oriented to bring it onto some red blocks with another Shy Guy. The switch also disables a column of blue blocks in front of the Goal Door. The Mini Luigi can now be initiated.
The toys must then travel on conveyors to arrive at a Red Color Switch. The switch disables several blocks in front of the door while also opening access to a Yellow Color Switch at the top left, with the Shy Guys currently located on red blocks dropping to the bottom of the stage. The Minis should use red Split Pipes to warp to the top left again and then go up a diagonal Purple Conveyor to get to the Yellow Color Switch. This switch disables the last column of blocks before the door and also sets free two Shy Guys nearby, which must be brought on conveyors to the bottom of the stage where the other Shy Guys currently are.
As the Minis head to the base of the level where the Goal Door is located, they must use conveyors and pick up a pair of Hammers at the right to destroy the Shy Guys gathered before the door. The Minis eventually enter the door and the level is cleared.
The M Coin is located right in front of the Mini Luigi, past an indentation with a Shy Guy. It can either be reached with a Purple Conveyor leading to it from the right, or by pressing the Blue Color Switch again after the Shy Guy is dropped on the conveyor below and using the now solid blue blocks to cross the gap from Mini Luigi's starting position.
