Level B-22 is the sixth course in the Bonus 3 set and the twenty-second Bonus Level overall in Mario vs. Donkey Kong: Tipping Stars. It is set in Clattering Cabin and is unlocked by earning 85 trophies.
The course is a collection of Magnets with large clutters of Pink Block spaces surrounding them. The spaces can be turned into actual Pink Blocks to aid the Minis in various ways, such as helping them commute from one Magnet to another or change direction on one. Several Fire Piranha Plants also appear, shooting fireballs in spaces between Magnets.
The Mini DK starts on the top layer with its back turned to the Goal Door, which is guarded by a Fire Piranha Plant. The Mini Luigi starts right under the Mini DK, while the Mini Toad starts further to the right on top of a small Magnet. Many bonuses are scattered throughout the entirety of the course, requiring the toys to tread along the Magnets and avoid Fire Piranha Plants to collect them. Additionally, the bottom of the stage is almost entirely covered in spikes. In order to reach the exit, the Minis must use Pink Blocks to climb up to the Magnet on the ceiling, picking up a pair of Hammers on their way to destroy the Fire Piranha Plant lying at the left end of the Magnet. Having defeated it, the risk of fireball damage is eliminated, allowing the Minis to simply use the door and clear the level.
The M Coin is found towards the bottom, at the mouth of a Fire Piranha Plant under a "U"-shaped Magnet. As they descend on the rightmost Magnet, the toys pick up a pair of Hammers which is acquired temporarily. The toy that carries them must be forced to fall on the ground underneath and brought onto the small Magnet on the left, where its direction should be changed with Pink Blocks. Going around the Magnet, the Mini encounters and destroys the Fire Piranha Plant, safely collecting the coin afterwards.
