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, only appearing 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.

Magnetic Blocks
Magnetic Blocks are like the Pink Blocks that can be picked up and dropped in certain areas. However, the Mini Marios can stick on these and walk sideways and up-side-down. Only a certain amount of Magnetic Blocks can be placed on the course at one time, so the player might have to erase some to make more somewhere else.

Swing Bar
Mini Marios can jump on Swing Bars (by sliding up on the touch screen). Then the player must spin the wheel on the side. Once the Marios are spinning fast enough, the player can slide up on the screen and make them jump high into the air. Mini Marios can also climb across these to get closer to the goal without falling of the course. To get off a swing bar, the player needs to slide down on the touch screen.

Rotating Magnet Stick
The Mini Marios can walk on the Rotating Magnet Stick sideways or up-side-down since it is metal. When the Marios are on it, the player can spin the wheel at the end and flip the Mini Mario to the other side of the bar. This can be useful to get in closed areas and avoid enemies.

Donut Blocks
When a Mini Mario goes on a Donut Block, the block will glide downwards because of the extra weight. If the Mini Mario doesn't jump off fast enough, it will fall into spikes and break. Donut Blocks can let the Mini Mario glide down and reach a lower area that couldn't be accessed without the blocks.
