Magnet Mania (Mario vs. Donkey Kong: Minis March Again!)

Magnet Mania (also called Floor 3, listed as Floor 2 in the PAL version) is the third floor in Mario vs. Donkey Kong: Minis March Again!. It is largely based on the floor of the same name from Mario vs. Donkey Kong 2: March of the Minis, as they are both mechanical themed floors containing objects such as Conveyors and Magnet Rods. It features Capture Kongs, Thwomps, Spikes, and Pokeys. The music is a cover of the underground theme from Super Mario Bros., which was also featured in the March of the Minis version of the floor. The Plus version of this floor adds Fire Piranha Plants and red and yellow Color Switches.

The world is set in a storage facility, as pipes, stacks of multi-colored crates and mechanical hands carrying other crates can be seen in the background.

Once the boss level is beaten, the player moves on to Jungle Rumble.
