Magnet Mania (Mario vs. Donkey Kong 2: March of the Minis)

Magnet Mania is the fourth floor in Mario vs. Donkey Kong 2: March of the Minis. This floor introduces Magnet Ground, Magnetic Blocks, and Rotating Magnet Sticks, which allow Minis to walk on them in any direction, including on walls and upside down. The floor's background features a system of connected pipes and a sewer grate which lets in light. The level themes on this floor are arrangements of the "Underground Theme" from Super Mario Bros.

Swing Bars are introduced on this floor in Room 4-2, and can be used to help Minis navigate certain areas and to fling them upwards into the air. Donut Blocks are also introduced on this floor, appearing only in Room 4-8 and Boss Game 4. They fall when a Mini walks over them, similarly to their appearance in other Super Mario games. Newly introduced enemies on this floor are Cool Kongs and Sparkies, while Piranha Plants, Shy Guys, and Thwomps return from previous floors.

Upon completing Boss Game 4, the Magnet Mania construction kit is unlocked for the Construction Zone. After being defeated in Boss Game 4, Donkey Kong flees to Lava Dome.
