A Piranha Plant, known as Packun Flower (パックン フラワー) in Japan, is an enemy almost always portrayed as a leafy, green stalk topped with a white-spotted red or green globe and sharp teeth.
Piranha Plants are large, carnivorous plants encountered throughout the Mario series; Piranha Plants are seemingly based-off Venus Flytraps, eating anything that approaches them. The head of a Piranha Plant is most commonly either red or green with multiple other colors. Originally, Piranha Plants were found exclusively in pipes, either darting-out and biting anything near or remaining still and spitting fireballs. Currently, Piranha Plants can be found both in and out of pipes and their fire-breathing ability is now rarely used.
