Mega Board Mayhem

Mega Board Mayhem is a board from the extra room hosted by Thwomp in Mario Party 4. Thwomp gives no reason he built it, except that it took him months to make it, and that he is proud of the results. Here, Thwomps are in charge of the shops, and many Thwomps, Whomps, and a Ztar hop and dance 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 is simply to get as many coins as possible. To do that, there are many item spaces and Item Shops around, where the players can get Mega Mushrooms, Super Mega Mushrooms or other items to steal coins from other players.
