Piranha Flower

Piranha Flowers are enemies in Super Mario 64. They are variants of Piranha Plants that can appear from the ground and shoot fireballs at the player, before later disappearing afterwards. They can be defeated by being jumped on or punched. Notably, in Tiny-Huge Island's large form, defeating a group of large Piranha Flowers rewards the player with a star.

Different Fire
Piranha Flowers usually only spit small red fire that dissipates shortly after it is emitted. However, in some personalized copies, some have reported different types of fire, such as bouncing fire or a line of fire. People have also reported there being no fire at all, and the Piranha Flowers function as Piranha Plants.
