Shy Guy Says

Shy Guy Says is a 4-player minigame in Mario Party, Mario Party 2 and Mario Party: The Top 100. In Mario Party and Mario Party: The Top 100, a Pirate Guy appears on a ship and the players are in barrels connected by rope to a ship, and in Mario Party 2 a Shy Guy stands on a rainbow with a bow and a quiver, with the players being attached to balloons. In the Mario Party: The Top 100 version of the game, the Pirate Guy has its Mario Party 8 appearance. Its name is a reference to the game "".

Gameplay
Players have to raise the same color flag as the Pirate Guy or Shy Guy. The Pirate Guy or Shy Guy's flags show the button used to raise that flag: for white and  for red. Players can choose between raising a red or white flag. If one of the players raises the wrong color flag or does not raise any flag, the Pirate Guy or Shy Guy eliminates the player from the minigame by using a sword to cut their rope in Mario Party and Mario Party: The Top 100, or by popping their balloon using a bow in Mario Party 2. In Mario Party and Mario Party 2, the Pirate Guy or Shy Guy will sometimes raise two flags at once, then putting one of the flags away early, while in Mario Party: The Top 100, the Pirate Guy will sometimes take out a flag and immediately put it away. When raising two flags at once, the Pirate Guy or Shy Guy can also raise a flag after lowering it and lower the other one. The last player attached to the ship or their balloon wins the game.

In Mario Party 2, a bypassing Lakitu appears, which serves as timestamp for the game. If the player does not raise a flag before the Lakitu has gone offscreen, the Shy Guy will pop their balloon.
