Magma Mine

"Magma Mine" is one of the seven boards in Mario Party 9. The players ride in a minecart. The mini-boss is a giant Spike. While the actual boss which is fought through a bowser gate is a Chain Chomp.

Layout
The players start out at the bottom of the mine, in front of a circle of lava. The players ride around the circle to a large ramp leading up. About midway is the boss castle where the Spike is fought. After the battle the players keep following track to eventually reach the top where the bowser gate is located. It should be noted that this board has a few different spaces that no other board has. This particular space rises the lava when landed on. If the player is the captain that made lava rise, he or she will lose half of their Mini Stars. Another note is the strange bone-like creature beside the boss castle, it resembles a Bone Dragon from Yoshi's Story.

Spike Boss Battle
Nothing is known about this battle.

Chain Chomp Boss Battle
The battle takes place at the peak of mine. The players start out behind minecarts with cannons on them. The Chain Chomp appears in front of the minecarts. The players must choose the correct path to reach a minecart. Once they reach the minecart, the cannon shoots hitting the Chain Chomp thus, giving the player points. Possibly, if the player chooses the wrong path, the Chain Chomp hurts the player?
