Room B-1

Room B-1 is the first course of the Basement in Mario vs. Donkey Kong: Minis March Again!. It is unlocked by earning 40 bronze stars or better from previous levels.

The course features three mini toys.

Overview
The minis begin on different levels starting from the bottom of the course, with the Goal Door further towards the top at the right. The way to the Goal Door is a blue bridge, which is initially retracted, leaving some spikes underneath open. Throughout the course, the minis have to consequently reach and push Color Switches that extend bridges to other color Switches until they can access the Goal Door, with guidance from the player's Pink Blocks.

The first Color Switch to be reached is a Red Color Switch, located near the bottom left. Pushing it will extend a red bridge at the bottom of the level, leading to a Yellow Color Switch. To reach it, the minis must enter the cyan Split Pipe at the bottom right, which will warp them in front of a gap that can be crossed with Pink Blocks; following that, the player has to activate a Pop-up Gate to change the toys' direction and head back into the cyan Split Pipe, which will warp them back to the bottom, leading to the Yellow Color Switch. The Yellow Color Switch in turn extends a yellow bridge to the right, allowing access into a yellow Split Pipe located a level above at the right. The pipe warps the toys to the top of the course, where they have to be guided with Pink Blocks to a Blue Color Switch on a platform lower to the right. The switch extends the blue bridge underneath that leads to the Goal Door.

Mini Mario Card
The Mini Mario Card is in an alcove near the top left, under the yellow Split Pipe. When the minis reach the top of the level, before being led to the Blue Color Switch, they should fall into the gap succeeding the yellow Split Pipe and land on an extended blue bridge. Soon after, the player needs to use Pink Blocks to change the toys' direction to the left, towards the Mini Mario Card.
