Herbicidal Maniac

Herbicidal Maniac is a 2-vs-2 minigame in Mario Party 7. The minigame's name is a portmanteau on "homicidal maniac", which is a term that refers to a person with an insane desire to kill other people, and "herbicide", a chemical used to kill plants.

Introduction
Piranha Plants and bombs emerge from all of the pipes, and then go back in as the players' pipe platforms move up.

Gameplay
Two people on each team have to shoot all of the Piranha Plants that pop out of the holes three times. However, if a bomb is hit, many more Piranha Plants will appear, making it more difficult for the player to win. The easy way to identify the player's target cursor is that the first player has a round one and the second player has a square one.
