Bowser's Magma Mountain

"Bowser has failed to bring your adventures to an end. He is entrenched in his volcano and is forcing you to fight! Bowser awaits you at the volcano's summit. Whoever can defeat that Bowser is a true Super Star."

- Koopa Troopa

Bowser's Magma Mountain is Bowser's unlockable board in Mario Party. It is purchasable from the Mushroom Shop for 980 coins. Players need to collect stars to "defeat" Bowser. The board is set on a huge volcano with a one-way path to the top of the board, but with many junctions. Every junction had a green volcano-head statue with a Star sign, and Bowser's face. Bowser's voice was heard, asking players if they wanted to take a shortcut up the mountain for 10 coins. If the player accepts, then they would pay the fee, and a roulette block will appear showing a star and Bowser's face. If the player got the Star, they would be allowed to take the shortcut. However, if they got Bowser's face, they would have to continue on their present route with no refund. A purple volcano-head statue was on the top of the mountain, and was the most important one. When a player got here, they would be forced to hit another roulette block (this one free of charge). Getting the Star picture took them to Boo, and Bowser's face took them to Bowser, where he stole either coins, or a Star (depending on yet another roulette block). If a player steps on a Happening Space, the volcano erupts, sending flaming rocks on the board and turning all the Blue Spaces into Red Spaces for two turns.

At the end of the game, the winner's stars form into a large star that charges up, and destroys the volcano part of the mountain that Bowser is in, sending him flying upward and falling back down on his side. As Bowser wallowed in pain, the winner would jump on him, then in front of him, as the players in 2nd, 3rd, and 4th watched. Toad, Koopa, Boo, and the Star soon joined them.
