Room 3-4 (Mario vs. Donkey Kong: Minis March Again!)
Room 3-4 (titled Room 2-4 in the British English version) is the fourth course of Magnet Mania in Mario vs. Donkey Kong: Minis March Again!. It contains Pop-up Gates, which can be activated in front of the mini toys to block their path and force them to turn around.
The course features three mini toys.
The course has a tall layout. On the sides, there are several Split Pipes that connect different floors. Two minis start in the bottom left, while the third mini starts across a pit of spikes on the same level. Upon activation, the third mini will enter a yellow Split Pipe and exit out on a higher floor, where the player needs to activate a Pop-up Gate to change the toy's direction before it falls onto some spikes and help it re-enter the yellow Split Pipe to return to the bottom floor. Using Pink Blocks, the toys must be guided to the cyan Split Pipe on the bottom, which transports them to the top of the stage where the Goal Door is located.
Mini Mario Card
The Mini Mario Card is located on a platform just above the lone mini toy. The minis can be guided there with Pink Blocks to obtain it.
