Jumping Piranha Plant

The Jumping Piranha Plant (alternatively Jumpin' Piranha Plant, misspelled in the Super Mario World ending sequence as Jumping Pirhana Plant) is a version of Piranha Plant that is not rooted to the ground.

Super Mario World
Jumping Piranha Plants made their debut in Super Mario World as the most frequent Piranha Plant enemies in the game. Most of them live in Warp Pipes, but some can be found hiding in bushes. Their propeller-like stems enable them to fly up quickly out of their spot and descend slowly back in, damaging Mario or Luigi at direct contact. However, the playable characters can Spin Jump on them without getting harmed, although this will not inflict damage on the enemy either. A Jumping Piranha Plant can be defeated by shooting a fireball at it as Fire Mario or Fire Luigi, or by touching it while invincible.

After the Special World is completed, Jumping Piranha Plants turn into Jumping Pumpkin Plants, which look like jack-o'-lanterns. However, they function exactly the same.

Super Mario Advance 4: Super Mario Bros. 3
Jumping Piranha Plants return in Super Mario Advance 4: Super Mario Bros. 3. They only appear in World-e's e-Reader accessible level, Ground Work. The Jumping Piranha Plants behave exactly similar to that of Super Mario World, though their appearance is pretty much identical to Super Mario Bros. 3 's original Piranha Plant species, save for their propeller-like leaf.

Super Mario Maker / Super Mario Maker for Nintendo 3DS
Jumping Piranha Plants reappear in Super Mario Maker and Super Mario Maker for Nintendo 3DS, only appearing in Super Mario World style replacing Piranha Plants. When shaken, however, they turn into Fire Piranha Plants instead of Fire Jumping Piranhas.

Trivia

 * In the English instruction booklet of Super Mario World, the Jumping Piranha Plant is described as a tropical version of the "Volcano Plant" (likely referring to Volcano Lotus); however, the Japanese instruction booklet correctly refers to it as a Pakkun Flower (Piranha Plant).
