Room 4-5 (Mario vs. Donkey Kong: Minis March Again!)
Room 4-5 (titled Room 3-5 in the British English version) is the fifth course of Jungle Rumble in Mario vs. Donkey Kong: Minis March Again!. The course introduces Polterguys, which can be turned into solid harmless blocks and back by pressing a Color Switch of the same color as them.
The course features four mini toys.
One pair of minis starts in the bottom left, while another pair starts in the bottom right. Starting from the left, the toys need to be led with Pink Blocks towards a Ladder, which they will climb and reach a Red Color Switch on a girder at the top. By pressing it, a "staircase" of red Polterguys on the left will turn harmless, enabling the minis to reach the Goal Door at the top left.
Mini Mario Card
The Mini Mario Card is beside three yellow Polterguys on a platform at the top of the course, left from the Ladder in the middle. A Yellow Color Switch at the bottom can be used to turn the Polterguys into blocks if needed, although they are already in this state at the start of the level. From the bottom right, the minis should use Pink Blocks and a Ladder and hop over the yellow Polterguys to reach the card. However, a few red Shy Guys arranged before the Goal Door must be turned into solid blocks beforehand, as the minis will fall onto them immediately after collecting the card. To do this, the player should lead the minis to the Red Color Switch at the top.
