Pier Pressure

Pier Pressure is a Free-for-All minigame featured in Mario Party 9. The name is a pun on the phrase peer pressure, where one conforms to how his/her friends think or behave. The minigame is similar to Cheep Cheep Chance from Mario Party DS, Bowser's Bigger Blast from Mario Party 4, and Cut from the Team from Mario Party 8.

Introduction
An underwater shot shows Cheep Cheeps and Urchins swimming around. The camera then goes above water and shows the pier and the players.

Gameplay
Before the game starts, a "spinning" arrow chooses who goes first. The selected player takes a turn, and the players to their right follow in order.

Players try to pick fishing lines that they think have Cheep-Cheeps on them. If any players should pick a fishing rod with an Urchin, they are knocked into the water and eliminated. The game is purely luck-based; there is no way of telling whether a rod has a Cheep-Cheep or an Urchin hooked to it, even if the line moves in a different way from another.
