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 layout of this level, consisting of numerous floors, is largely occupied by conveyors and rivets for Purple Conveyors. Movement depends on using these mechanisms, as well as Split Pipes placed in different corners of the stage. Shy Guys are also involved in this course, appearing on blocks that can be deactivated by pressing Color Switches. This action causes the Shy Guys to drop on conveyors, which can then be oriented with conveyor switches to herd them in a certain spot where they can be easily defeated with Hammers.
The two Mini Peaches start at the bottom of the stage, near the Goal Door which is initially inaccessible due to several walls of color blocks placed before of it. The toys face a red Split Pipe that warps them to the top left. Below this area stands Mini Luigi, facing a Shy Guy which it cannot surpass unless the other Minis press a Blue Color Switch right above the Mini Luigi. This causes the blocks under the Shy Guy to disappear, dropping the enemy onto a conveyor which should be used to bring it onto some red blocks with another Shy Guy. Pressing this switch also disables a column of blue blocks in front of the door.
The toys must also travel on conveyors to arrive at the Red Color Switch towards the right side, which likewise disables several blocks both under Shy Guys and in front of the door. It also disables some blocks that obstruct the Yellow Color Switch on the top left, where the Minis should head next by warping with the red Split Pipes and going up a Purple Conveyor. Pressing it disables the last column of blocks before the door and also sets free two Shy Guys near the switch.
As the Minis head to the base of the level where the Goal Door is located, they must pick up a pair of Hammers to destroy the crowd of Shy Guys formed before the door, as a result of them being brought there by conveyors. The Minis eventually enter the door and the level is cleared.
The M Coin is located right in front of the Mini Luigi, past the 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.
