Tidal Fools

Tidal Fools is a 4-player and duel minigame from Mario Party DS. This is a bonus coin minigame where the characters scatter around the edge of the coast, and collect coins dumped by the backwash of the sea.

Gameplay
The goal of the game is to collect as much coins as possible - the total collected would be transferred to your player once the game returns to the board. That said, before the coins arrive the sea will toss high tides over the coast which has to be avoided - use the control pad to move around and stay way form it.

The backwash of the wave deposits a bunch of coins upon the coast, including red ones which are worth 5x the value of standard coins. Failure to avoid the incoming swash beforehand though will result in your character being washed away and suffer dizziness, consequently missing the chance to collect the coins as a result.

The process repeats for another three times, until the 30-second limit expires.

Trivia

 * The minigame's title is derived from tidal pools, which are small shallow bodies of water found along the coast during low tides.
 * This is the fifth minigame out of the game's list that features bonus coins, and only the second one in the 4-player selection; the other is Shortcut Circuit.
