Chicken!

Chicken! is a duel minigame found in Mario Party Advance. Its name comes from the insult that is hurled at someone who is too scared to go somewhere or do something.

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 flattened by Thwomp or is the last one to flee. If both players are flattened, then the match is a draw.
