Piranha Plants

Piranha Plants are a carnivorous species of plant from Mario's dimension, mainly residing in pipes and taking a bite at anything that approaches. In particular, the "Jumping" piranha plant is a type that is not rooted to the ground, and so is capable of leaping into the air with its propeller-like leaves to snatch prey; occasionally the plant also spits out two fireballs. In the "Dimension" saga, several piranha plants are somehow brought into Zim's dimension, to hinder the alliance of heroes in their Hunt for the Chaos Emeralds. Specifically, the plants attack Luigi while he is in the depths of the Cess Pool, using their maneuverability and sharp teeth to constantly inflict pain on him; however, as they all converge on his seemingly helpless form, he suddenly uses his cape to spin around and around to shake all of them off in one swift attack, causing the plants to scatter and retreat.
