Mega Board Mayhem

Mega Board Mayhem was a board from the extra room hosted by Thwompin Mario Party 4. Thwomp gave no reason why he built it, except that it took him months to make it, and was proud of the results. Here, Thwomps were in charge of the shops, and many Thwomps, Whomps, and a Ztar hopped and danced around the bottom of the board (completely for show).

There are no stars to collect on the board, no special events, and no minigames each round. The goal was simply to get as many coins as possible. To do that, there are many item spaces and shops around, where the players could get Mega Mushrooms, Super Mega Mushrooms or other items to steal coins from other players.
