Room 1-1 (Mario vs. Donkey Kong: Minis March Again!)
From the Super Mario Wiki
Room 1-1 (titled Room G-1 in the British English version) is the first course of Mini Mayhem in Mario vs. Donkey Kong: Minis March Again!. It introduces Pink Blocks, which act as solid platforms that can be collected and repositioned in designated spaces.
The course features two mini toys.
The minis start on a straight lane towards the Goal Door, with a pit of spikes in front of them. The player needs to build a bridge of Pink Blocks over the pit of spikes so that the minis can cross it safely and reach the goal. The minis can collect the Coins on an upper platform if the player puts the Pink Blocks in a staircase formation towards the platform.
Mini Mario Card
The Mini Mario Card is located past the pit of spikes. The minis will reach and collect it shortly after they cross the pit.
