Bowser Station

Bowser Station is the sixth board featured in Mario Party 9, and the final stage in Solo mode. The mid-boss is Bowser Jr., and the boss is Bowser himself.

Layout
The board is a linear board like the ones featured in past Mario Party games. There are two methods to earning Mini Stars on this board: by running into them, or by earning them from the Jackpot Machine. The machine's Mini Star total increases whenever the player lands on Jackpot+ Spaces, a space that is exclusive to this board. When landed upon, the Jackpot Machine's total Mini Star count will increase by an amount equal to the number imprinted on the space. Once the number on the machine reaches at least twenty, the players will play a minigame to determine who earns all the stars. Players may also earn them by landing on a Jackpot Space, which automatically gives the captain who lands on the space all the Mini Stars in the Jackpot Machine. By default, the machine will have six Mini Stars, and will suck up one more than that when all the Mini Stars are removed from it.

The mid-boss for this stage is Bowser Jr., who is faced in the minigame Bowser Jr. Breakdown. After this, Bowser will appear on the stage with his Koopa Clown Car and challenge the player himself, creating a Boss Battle Space and Bowser Gate at the beginning of the stage.

There are three Captain Events on Bowser Station: Heart Star Colony, Bingo Colony, and Speed Star Colony. On Heart Star Colony, the three other players roll Dice Blocks with red, green, and blue hearts on them. The captain then rolls the same Dice Block three times, and, if any of his or her results match the other player's, they both receive two Mini Stars. If there's 3 players, a Mechakoopa joins the event. If there's 2 players, 2 Mechakoopas join the event. On Bingo Colony, players roll dice blocks, and the resulting number will be lit up on the bingo board. Once one of the players obtains three lit up spaces in any direction, he or she will receive three Mini Stars times the number of spaces the bingo consists of. On Speed Star Colony, the captain assigns each player a track, and they race to reach the goal first, with one being the shortest and the others being slightly longer than the last; however, there are also Dash Spaces scattered around the area.

Also, on the "Almost There!" event, Bowser will forcefully turn several spaces into Bowser Spaces, instead of asking the captain if he or she "wants a WHOLE TON of presents".

Afterward, the players face Bowser in the game Bowser's Block Battle. Once he is defeated, the players will have earned the Mini Stars back, and they will be set free.

Bowser Jr. Boss Battle
Players fight Bowser Jr. on a space station. Players roll Dice Blocks to try and get the gauge to reach a multiple of three. The player who does so will attack, and the meter will restart.

Bowser Boss Battle
Bowser is fought on a platform out in space. He is giant during this battle, and players try to damage him by tossing the Dice Blocks he throws onto the arena to make them land on their faces.
