Floor 4 Donkey Kong
Floor 4 Donkey Kong (titled Floor 3 Donkey Kong in the British English version) is the Donkey Kong level of Jungle Rumble in Mario vs. Donkey Kong: Minis March Again!. It is the last boss fight in the game's Normal Mode. Like in Floor 2 Donkey Kong, the player faces the boss with a cannon that can be rotated around an axis by spinning a wheel on the touchscreen. The player has a reserve of six Mini Mario toys that can be shot from the cannon.
The level is almost identical to the boss battle of Jungle Hijinks from Mario vs. Donkey Kong 2: March of the Minis. Donkey Kong constantly moves between several ropes on the top screen of the console. Unlike in previous battles, he does not attack the minis, but is also impervious to direct shots and will break any Mini Mario that is launched into him.
There are five red girders above DK, each holding a banana bunch underneath. Shooting a Mini Mario on top of a girder will cause the corresponding banana bunch to fall off, with another banana bunch respawning in its place shortly afterwards. The bananas must be dropped on Donkey Kong to damage him, with the player being careful not to drive any Mini Mario into a falling banana bunch. For a short time after each hit, DK moves more aggressively while glowing red and being invulnerable to any attacks. Blue clocks occasionally appear and move along a rope, then fall off; when collected, they add 30 seconds to the time limit. The level also introduces dark gray clocks, which take away 30 seconds when collected instead.
After Donkey Kong receives the first hit, a Snapjaw will spawn on the rightmost rope and move up and down, breaking any Mini Mario that comes into contact with it. A secondary Snapjaw will appear later on in the battle on the leftmost rope. After DK is hit a second time, a Nitpicker appears just above the player's cannon and flies around in an attempt to obstruct the minis; each time DK is hit, the Nitpicker temporarily moves around more frantically and also drops a few eggs in different places (two after most hits, four after the second-to-last hit). Both the Snapjaw and the Nitpicker can be destroyed by dropping a banana bunch on them, but will respawn a while after this.
The player must drop six banana bunches on Donkey Kong to defeat him.
Mini Mario Card
The Mini Mario Card appears after Donkey Kong is hit a second time, in the place of the banana bunch that hit him. To collect the card, a Mini Mario must simply be shot into it. After collecting it, a banana bunch will appear again in that place. Landing a Mini Mario on the girder above the Mini Mario Card has no effect on the item.
