Jungle Rumble

Jungle Rumble, also called Floor 4 (Floor 3 in the PAL version), is the fourth floor in Mario vs. Donkey Kong: Minis March Again!. The focus of this floor are the Color Blocks, which can be changed from solid to clear and vice-versa by pressing a Color Switch of corresponding color. Color Switches can also be used to turn some enemies, such as Shy Guys and Polterguys, into harmless blocks. Snifits and Polterguys are introduced on this floor while Shy Guys, Capture Kongs and Circus Kongs make a return. Defeating Donkey Kong on this floor grants access to the Jungle Rumble Construction Kit in the Construction Zone, which contains all the elements present on this floor.

The background consists of a dense palm tree jungle over a blue sky painted on a wall. The music is the same as in Jungle Hijinks from Mario vs. Donkey Kong 2: March of the Minis, being a rendition of the "DK Island Swing" track from Donkey Kong Country.

New elements
This floor contains a single tutorial level that showcases Color Blocks. The player can access and play it by tapping on the "?" icon in the bottom right corner of this floor's level select screen.

Plus Mode
In Plus Mode, this floor is subtitled Floor 4+ (Floor 3+ in the PAL version). Conveyor Belts, Rotate Pipes, Pokeys and a Thwomp are present here alongside previously established features of this floor. Beating Jungle Rumble in the Plus version adds all these elements to its corresponding Construction Kit.

The backdrop of this floor is nearly identical to the Normal Mode counterpart, except for the light-purple sky. The soundtracks that play in Rooms 4-1+, 4-2+, 4-4+, 4-5+, 4-7+, 4-Key+ and 4-SP+ are variations of two of Fire Mountain's soundtracks from Mario vs. Donkey Kong, while the track that plays in Rooms 4-3+ and 4-6+ is a variation of one of Twilight City's soundtracks also from Mario vs. Donkey Kong.
