Koopa's Seaside Soiree

Koopa's Seaside Soiree (Koopa's Seaside Soirée in the PAL region) is an island resort board hosted by Koopa in Mario Party 4. He built it because he always wanted to have a place to hang out by the sea, and wanted his friends to have fun in it. Here, Koopas are everywhere, and are in charge of the games and shops (the one hosting wore stripe pants and a bow tie).

The main attractions here are the dolphins and the Koopa Kabana. Players that land on a Happening Space next to a dock (with a picture of a fruit on it) summon a Dolphin that takes them to another dock with the corresponding picture. One of the Koopas constantly tries to get coins from the players so that he can build the resort hotel, the Koopa Kabana. Every time players pass the Koopa space, they pay an upwards of five coins. The more coins invested, the better the Kabana looks. If players land on one of the ? Spaces in front of it, the Koopa asks that they pay the fine for staying at the Kabana, which is the amount of coins that is currently invested. When the fee is paid, a tidal wave comes in and destroys the Kabana, so the investments start all over again to build another one.

The Item Mini-Game of the board involves hitting one of three melons that have an item in each. Players are spun around before they choose, making it harder to make a choice. The Coin Mini-Game involves fishing. Players are given the choice of one of the fishing rods. The chosen rod is used to reel in the fish that gets caught on it. The bigger the fish, the more coins players win.

In Story Mode, if the player beats their opponents on the board, Koopa challenges them to a Mini-Game called Kareening Koopas in order to win his present.

Trivia
