Room 3-Key+ (titled Room 2-Key+ in the British English version) is the eighth Plus Mode course of Magnet Mania in Mario vs. Donkey Kong: Minis March Again!.

The course features three Mini Mario toys, one of which carries the key needed to unlock the Goal Door.


The Mini Marios start in a triangle formation in the center of the course; two of them on Magnet platforms and the third on some Pink Blocks in an enclosed area. Using Pink Blocks, the minis have to be guided to one of the vertical spin-bar magnets on the sides of the level and then flipped to the other side of them, allowing the toys to climb to the top of the stage. Once there, the minis can be guided with Pink Blocks to the Goal Door in the top left from one of the platforms nearby. The Key Mini Mario should be brought to the door first to unlock it, followed by the other two Mini Marios.

Mini Mario Card[edit]

The Mini Mario Card is on a small girder platform at the top of the stage, near the Goal Door. Once in the top area, the minis can be led to the card with Pink Blocks.


The M-Token is at the top of the rightmost spin-bar magnet, on its left side. The minis can simply be guided with Pink Blocks to the spin-bar magnet which they will start climbing. Immediately after collecting the token, the minis should be flipped to the other side of the spin-bar magnet to avoid walking into a pair of Piranha Plants ahead of them.
