Chicken!

Chicken! is a duel mini-game found in Mario Party Advance.

Gameplay
Both players try to stay under the Thwomp for as long as they can, but must also avoid being squished by it. The players can fake out by walking out and go back in to make the other player nervous. If one player flees, the other has a chance to get out to win. Victory goes to whoever isn't squished by Thwomp or flees later. If both players are squished, then it is a draw.

Trivia

 * The name of the game is a word that someone is called who is too scared to go to a place they don't want to go in.
