Shy Guy Says

Shy Guy Says is a 4-Player minigame in Mario Party, Mario Party 2, Mario Party: The Top 100, and Mario Party Superstars. In Mario Party, Mario Party: The Top 100, and Mario Party Superstars, a Shy Guy appears on a boat, and the players are in barrels connected by rope to the boat; in Mario Party 2, a Shy Guy stands on a rainbow with a bow and a quiver, with the players being attached to balloons. The Mario Party: The Top 100 and the Mario Party Superstars versions of the game are based on the Mario Party version, though the Shy Guy wears only a hat instead of a full pirate outfit. The minigame's name is a reference to the game.

Gameplay
Players have to raise the same color flag as the Shy Guy. The Shy Guy's flags show the button used to raise that flag: in Mario Party and Mario Party 2,  in Mario Party: The Top 100, and  in Mario Party Superstars for white, and  in Mario Party and Mario Party 2,  in Mario Party: The Top 100, and  in Mario Party Superstars 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 Shy Guy eliminates the player from the minigame by using a sword to cut their rope in Mario Party, Mario Party: The Top 100, and Mario Party Superstars or by popping their balloon by using a bow in Mario Party 2. In Mario Party and Mario Party 2, the Shy Guy will sometimes raise two flags at once, then put one of the flags away early, while in Mario Party: The Top 100, the Shy Guy will sometimes take out a flag and immediately put it away. When raising two flags at once, the Shy Guy can also raise a flag after lowering it and lower the other one. Both of these techniques reappear in Mario Party Superstars. The last player attached to the boat or their balloon wins the minigame.

In Mario Party 2, a bypassing Lakitu appears, serving as a 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.

The music speeds up as the minigame progresses, which also occurs in Hexagon Heat in Mario Party 2. This does not occur in Mario Party: The Top 100.

Trivia

 * An alternate texture for the Shy Guy pirate is present in the game's files but went unused.
 * In Mario Party 2, Luigi's flags have a rendering issue that causes them to look as if they are not fully attached to the poles, an issue also present in Yoshi's red flag. Luigi's left wrist is also seen constantly twisting.
