Mario's Rainbow Castle

Mario's Rainbow Castle is Mario's gameboard in Mario Party. The cloudy board looks visually appealing to begin with, but players need to collect stars to restore the great rainbow of the castle. The board is a one-way path to the middle of the board (with 2 junctions). Players who make it to the center ride Fwoosh up to the tower, where either Toad, or Bowser wait. Toad doles out the stars as usual, but if players make it to Bowser, he awards them with a faux black star (Ztar) at the cost of 40 coins (which will not add to their star total by the way). After getting either star, Lakitu takes the player back to start. The Happening Space makes the tower turn around, replacing Toad with Bowser, and vice versa.

At the end of the game, the winner's stars form into a large star that makes a magnificent rainbow across the board. The winner, as well as the players in 2nd and 3rd place go up the rainbow to celebrate the victory along with Toad, Koopa, Boo, Fwoosh, and the Star. The player in 4th place attempts to travel up the rainbow too, but slips, falls, and is carried away by Lakitu.

Trivia

 * This board was most likely inspired by the course in Super Mario 64 named "Tower of the Wing Cap". Mario is also seen wearing a Wing Cap in the map's cast artwork (as seen below).
