DK's Jungle Ruins
DK's Jungle Ruins is the seventh board featured in Mario Party 9, and can be unlocked by purchasing it from the Museum for 500 Party Points. This board is not played in Solo mode, and is considerably different from the other six boards.
Instead of Mini Stars, players compete to acquire the most Bananas, and instead of Mini Ztars, players lost Bananas when the collect sinister Z-Bananas.
Since this board is controlled by Donkey Kong, players play games with the Kongs instead of having boss battles. The players play with Diddy Kong instead of a mid-boss battle and with DK himself instead of a final boss battle.
Layout
This board is a circle with no branching paths, much like Bowser Station. It is different in that the players complete two laps around the board, stopping at the same Boss Space to play games with both Diddy Kong and later Donkey Kong.
To further set it apart from other boards, in DK's Jungle Ruins Bananas, Banana Bunches worth three Bananas, Z-Bananas, and Z-Banana Bunches hover over each space instead of between spaces where Mini Stars and Mini Ztars tend to reside.
This is the only board to feature DK Spaces in Mario Party 9. Here they activate the Bananas Spin Wheel, which causes the Bananas and Z-Bananas around the entire board to spin, and the captain who landed on the space can jump to collect Bananas--and hopefully not Z-Bananas--as they pass.
The Captain Event here is Barrel Choice, which is played twice since the players makes two laps.
Barrel Choice
In this Captain Event the players watch as barrels are filled with varying amounts of Bananas and then shuffled. The captain then chooses which player claims the Bananas in each barrel.
The first time this Captain Event is played Diddy Kong attempts to distract the captain from watching as the barrels are shuffled. The second time both Diddy and Donkey Kong fill this role, and one of the barrels is filled with Z-Bananas
Diddy Kong Minigame
Instead of a fight, Diddy Kong asks the players to play a game with him. This game is Diddy's Banana Blast, in which the players launch themselves out of swaying Barrel Cannons that surround an area filled with Bananas in an attempt to collect the most. Unlike most Mario Party 9 minigames, in which the number of Mini Stars awarded for each place is predetermined, players earn as many Bananas as they collect. If players crash into each other, they fall back into a nearby Barrel Cannon and are momentarily stunned.
Donkey Kong Minigame
Like Diddy, Donkey Kong presents the players with a challenge rather than engage them in battle. This minigame is somewhat similar to Diddy's, although the players must launch themselves from Barrel Cannons on the bottom of the field to collect Bananas in the air. DK throws floating Barrel Cannons into the area that the players can use to launch themselves even higher into in order to reach Bananas hovering there.
