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 magnetic surfaces, 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 remixes 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 Room 4-DK. They fall when a Mini walks over them, similarly to their appearance in other Mario games. Newly introduced enemies on this floor are Cool Kongs and Sparkies, while Piranha Plants, Shy Guys, and Thwomps return from previous floors.

The Mini Marios' boss fight against Donkey Kong in Room 4-DK, referred to as Boss Game 4, plays similarly to Boss Game 2 in Room 2-DK, with several key differences. The spiked platform Donkey Kong is on sways left and right in an arc, rather than moving back and forth along a line. When Donkey Kong slams the spiked platform, Spiked Balls drop from its position, which destroy a Mini Mario upon contact. To defeat Donkey Kong, the player must shoot Mini Marios from a cannon, so that they either hit Donkey Kong directly or reach the Donut Blocks on the top of the screen, which can fall and damage Donkey Kong. However, if a Mini Mario reaches the top of the screen, but does not land on a girder or Donut Block, it will fall and break, regardless of whether it touches Donkey Kong. If all of the player's Mini Marios are destroyed, the game is over. After 6 hits, Donkey Kong is defeated and flees to Lava Dome.

Upon completing Room 4-DK, the Magnet Mania construction kit is unlocked for the Construction Zone.
