Mario Party 4/Koopa's Seaside Soiree

Koopa's Seaside Soiree is the fifth board. It has a difficulty rating of two out of three.

Ukiki's Banana Peel Junction
The banana peel gets the blame, but it may be possible to control your path. If you're at the junction, tilt in the direction you don't want to go. If an opponent is at the junction, tilt in the direction you want them to go.

Koopa Kabana
When you pass either Koopa mark, Koopa will request an investment of 5 coins or whatever lower quantity you have. There is no way to decline. If you land on an adjoining Happening Space, Koopa will sell you one night for the total investment. If you don't have that many coins, he'll bring the price down to whatever you have. Unless it's closed for repairs (the total investment is 0 coins), the Kabana will be destroyed by a big wave after you've paid.

Dolphin Fruit Pads
If you land on a Happening Space next to a Fruit Pad, a dolphin will take you to the corresponding Fruit Pad. The Watermelon Pad has three coins on the route.
