Pop-Star Piranhas

Pop-star Piranhas is a 4-player minigame found in Mario Party 5.

Gameplay
The players attempt to watch the Piranha Plants as they dance. Each Piranha Plant corresponds to a button on their pipe. One of the Piranha Plants dances a little differently than the others. When the music stops, players must choose the button that they think corresponds to the Piranha Plant that is dancing differently. The characters face away from the player so that players cannot copy each others' answers. When all players have guessed, or when the five second time limit runs out, all players reveal their guesses and whoever is correct receives a point. The player(s) with the most points after three rounds wins.

Trivia

 * Pop-star Piranhas was also one of the playable minigames in the Mario Party 5 demo on the Mario Kart: Double Dash!! bonus disk. Additionally, the mini-game was originally called Dancin' Piranha Plant before the name was changed in the final version.
 * The music the Piranha Plants dance to is a remix of Super Mario Bros.'s overworld theme. In the game's Sound Test, the songs that are playing in order are "Piranha Swing", "Piranha Ballad", and "Piranha Metal".
