Room 1-2 (titled Room G-2 in the British English version) is the second course of Mini Mayhem in Mario vs. Donkey Kong: Minis March Again!.
The course features two mini toys.
The minis start on a ledge on the left. In order to help the minis reach the Goal Door on the right, the player needs to put several Pink Blocks across a pit of spikes.
The Mini Mario Card is located under the girder that leads to the Goal Door. In order to collect it, the minis must be led there with Pink Blocks.
