Super Mario Series Piranha Plant Earrings

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.
The first appearance of Piranha Plants was first seen in World 1-2 of Super Mario Bros. as semi-common enemies. They are one of Bowser's soldiers of the Koopa Troop that conquers the Mushroom Kingdom since he attacked it. The Piranha Plants inhabit Warp Pipes and attack by biting Mario or Luigi if they were close enough to them or jump on these carnivorous plants. Oddly, Piranha Plants won't emerge from their pipe if Mario or Luigi are touching or standing directly on top of it.
