Mystery Land

Mystery Land is a board set in some ancient ruins in Mario Land in Mario Party 2. It is divided into four areas, to which people warp to each time they land on a Happening Space. They can also pay 10 coins to have a Bob-omb UFO take them to another area. Other interesting features on this board include the Shy Guy's Curse House, where a player can pay 5 coins to curse himself or herself or another player to reduce the number on their dice block to 1-3, rather like the Poison Mushrooms from later Mario Party games. The Item Mini-game is Mallet-Go-Round, and the Duel mini-game is Psychic Safari.

At the end of the game, a red Koopa Troopa comes and alerts the players that the treasure has been found. A cutscene then shows a green Koopa with a golden Bob-omb statue. Then the villain of the board, the Bowser Sphinx, comes to challenge the Koopa to guess a figure shrouded in shadow. The Koopa guesses incorrectly, saying that it's a cow, and Bowser says that's wrong. He puts the Koopa into a rock. Then, the winner of the game comes to confront him. The winner guesses Bowser's shadow riddle correctly, saying that the figure is him. The Bowser Sphinx disappears, a consequence of having his riddle guessed, and the statue breaks to reveal a Bob-omb Buddy that was trapped inside. The other Bob-omb Buddies come to take their rescued comrade away on their spaceship. The winner of the board is then congratulated by the other players, Toad, Koopa, and a Power Star.
