Waluigi's Island

Waluigi's Island is the unlockable board in Mario Party 3. It is an island based on industry and cleverness. Piranha Plants are even found working in cranes.

The island with all the dynamite is the first place players always go to. The Happening Spaces are dangerous here, because every time someone lands on one, the number in the center of the explosives would count down. It always starts on 5, but when it gets to 0, the dynamite explodes. Anyone caught in the blast loses all their coins (this scheme is similar to the Bowser Beam of Space Land from Mario Party 2).

Action Time is the main part of the board, where players who want to get off the dynamite island activate the gear in the center of the board. The four arrows on it (up, right, down, and left) would flash in clockwise order at a random speed. Players jump to the gear, and stop it when they land. The arrow that is flashing when they land is the path they have to take (if it stops at the down arrow, or if players take too long to act, they stay in the dynamite island).

The island with all the spaces in the middle is a unique part of the board. Every turn, the spaces (on the path, not in the middle) change to another type of space, and is always random to know which one they change to (also, players that land on ? Spaces next to one of the draw bridge cause one of the draw bridges to rise up, and the other to come down. This changes where players could enter or exit the space island).

Players that want to get to Boo have to take one of two paths, where one of them is booby trapped. If they take the path that has the trap, they are sent back to start. Wherever players go on the topsides of the board, they will always go to into red pipes that lead them to the green pipe near the start (similar to Luigi's Engine Room from Mario Party).

In Story Mode, the human player goes up against Waluigi and two other opponents. They battle here to get the Mischief Star Stamp that Waluigi stole. Winning here allows players to play this board in Party Mode.
