Eternal Star is the final board in Mario Party. It is unlocked by collecting 100 stars and completing Bowser's Magma Mountain. The board is a giant Star that was broken up by Bowser, and he even wrote graffiti over it. Players needed to collect stars to put the giant Star back together. Instead of Toad, players had to get the Stars from Bowser's cohoarts, the Baby Bowsers. To get Stars from them, players paid the 20 coin fee, but then had to to play a game with Dice Blocks, where the person with the highest number wins. If the player won, Baby Bowser gave up the Star, and left. If Baby Bowser won, he took a Star from the player! When all 7 of the Baby Bowsers are dipatced, 7 more will appear. The ? Space made Bowser use his magic to send all the players back to start. The board is made up of a system of Warp Machines that connect as the Warp Patterns made by Bowser. If a player was unlucky enough to get to Bowser, he would steal a star from them, then change the routes of the Warp Machines.
At the end of the game, the winner's stars formed into a large star that blasted Bowser and Baby Bowser into outer space, and the Giant Star was then put back together. It zoomed into an endless warp, taking the winner, the players in 2nd, 3rd, and 4th, Toad, Koopa, Boo, and the Star along for the ride.
