'''Room 4-Key+''' (titled '''Room 3-Key+''' in the British English version) is the eighth Plus Mode course of [[Jungle Rumble]] in ''[[Mario vs. Donkey Kong: Minis March Again!]]''.

The course features five [[Mini Mario (toy)|Mini Mario]] toys, one of which carries a [[key]] needed to unlock the [[Goal Door (Mario vs. Donkey Kong series)|Goal Door]].
==Overview==
The four keyless Mini Marios start in the top left, in the same area as the locked Goal Door. The Key Mini Mario starts lower to the right inside a passage. The Key Mini Mario must be brought to a blue [[Box Spring]] on the right side of the course, in such a way that the toy walks onto it from the right. The Box Spring should be used to bounce the Key Mini Mario to the upper platform on the left. To lead the Key Mini Mario to the door from here, the player can use either Pink Blocks or a yellow Box Spring. After the Key Mini Mario unlocks the door, all the other minis have to quickly follow and enter the door to clear the level.

There is a [[Capture Kong]] on the left side of the level. If any Mini Mario ends up captured by it, the Capture Kong can be brought past a bed of [[Spike Trap|spike]]s to a platform on the right and stunned by a Mini Mario with the Hammers located in the bottom right area.
===Mini Mario Card===
The [[Mini Mario Card]] is located atop a long [[girder]] platform in the top right. Three [[Shy Guy]]s patrol it. One of the minis has to be led to the pair of [[Hammer]]s located above a grid of Pink Blocks in the top middle. With the Hammers picked up, the mini should then be led to the platform with the Shy Guys and destroy them to collect the Mini Mario Card.

===M-Token===
The [[M-Token]] is located right behind the Key Mini Mario's starting position. To obtain it, the player has to direct a mini to it using Pink Blocks.
